What is an Activated Carbon Water Filter? 

An Activated Carbon Filter is a water filter used to remove contaminants from water that cause a negative impact on the taste, colour and odour of incoming water. Activated carbon is a very porous substance and is usually made from coconut husks, coal or bone that have been intensively treated with steam and with the absence of oxygen. one this treatment has taken place, the result is a very porous substance. Activated carbon is capable of absorbing thousands of different chemicals and harmful microorganisms. Just one pound of activated carbon has a surface area of about 125 acres.

How does activated carbon work?

Carbon has been used as a means of filtration for hundreds and even thousands of years. Activated carbon works by adsorption. the carbon attracts the solute contaminants and holds them to their porous surface. Due to their pores and their massive surface area, activated carbon is one of the best natural man made material available for adsorption. One all of the pores within the carbine have been filled, the carbon is then exhausted. there is no way to ‘regenerate’ the carbon rendering it no longer effective and requiring replacement.

the process of removing contaminants from water using activated carbon is not one that can be rushed. their needs a low permeate form for this process to be effective.

The permeate water passes over and through the carbon and negatively charged ions of the contaminants are then drawn to the top of the activated carbon.

How does an Activated carbon Water Filter work?

A carbon filter works in a very similar way to a regular filtration system, The main difference being that the filter media is activated carbon instead of resin. Another obvious differences is that the rinse cycle of an activated carbon filter is a 3 stage process a rather that the 5 stage process of a traditional water filter. There is obviously no brine tank and no requirement for brine draw or regeneration process for the resin. Instead a rinse cycle is used to agitate the carbon and clean away any contaminants it has previously removed from permeate flow and send it to drain. The volume of permeate and the contaminants prevalent within your permeate will determine the regularity of the regeneration cycle.

The three stage rinse cycle of an activated carbon filter comprises of :

  1. Backwash
  2. Slow Rinse
  3. Fast Rinse

What is adsorption and how is it different to absorption?

People are often confused by absorption and adsorption. They are similar actions and work in similar ways, they do however have fundamental differences.

The dictionary term for absorption is – “The process by which one thing absorbs or is absorbed by another”.

If you were to spill a glass of water, you would clear up the spillage using a tissue or kitchen towel. this is because these objects are absorbent. They attract the water in its entirety and suck it up through the kitchen towel until it reached the point of saturation.

The dictionary term for adsorption is – “ (of a solid) hold (molecules of a gas or liquid or solute) as a thin film on the outside surface or on internal surfaces within the material”

If you were to clear us that same spillage of water and you were to use a sheet of writing paper, the paper would become wet on it surface. it would take on some but not all of the water. If the water were to have a colorant added to it such as a dye or cordial, the paper, if left long enough would take on some of the coloured pigment, leaving the water behind.

This phenomenon is known as adsorption and works the same with carbon. if a piece of carbon was placed in a jar with a dyed solution, the carbon would attract the dye pigments sticking them to its surface and leaving the water behind.

Does it matter which type of Activated carbon I choose?

There are several types of carbon available for filtration and they all have different origins. some originate from bone, coconut shell, wood, peat and petroleum based residue. These substances are most commonly used as during the activation process or applied steam, their internal surface area increases dramatically and is accessible to vapour and fluid making it ideal for adsorption to take place.

All different types carbon work using the same basic principle of adsorption. they all contain micropores, mesopores and macro pores but again, this all depends on the originating raw material.

Because of their individualised characteristics, some carbons do work better at adsorbing specific substances so this should be considered when determining what substance you are hoping to remove.

Coconut shell has pores that are predominantly microporus in range (95%). This raw material is particularly useful for the adsorption of objects of a small molecular weight or applications involving a low concentration of contaminants.

In contrast to this, wood and peat based carbons have pores in the meso/macrorore range making it particularly good at adsorbing objects with a larger molecular weight or applications involving a high concentration of contaminants. An ideal function for this type of carbon is for the process of decolorisation.

A carbon that would place directly between the above two would be a coal based carbon.

What will activated carbon remove from my water?

 An activated carbon filter is ideal for the removal of chlorine, unwanted taste and odours, organics, unwanted colorants, ozone and metals.

Most UK regions dose their mains water with chlorine to disinfect and eliminate harmful microorganisms. Chlorine dosing also prevents water being contaminated through its journey through miles of underground plumbing systems. Regionally, chlorine levels vary between 0.1 – 0.5 ppm. This variation can create inconsistencies with a production line and in situations when consistency is key, a water filter is highly recommended. Chlorine is also considered as a strong oxidant and is not good for RO membranes and softener resins. because of this, carbon filtration is ideal for use as a pre treatment before RO or water softening.

What Chemicals will activated carbon remove?

activated carbon can remove hundreds of different chemicals from permeate but this is at varying levels –

 

A carbon filter can remove the following chemicals Very Effectively –

2 4-D, Deisopropyltatrazine, Linuron, Alachlor, Desethylatrazine, Malathion, Aldrin, Demeton-O, MCPA, Anthracene, Di-n-butylphthalate, Mecoprop, Atrazine, 1,2-Dichlorobenzene, Metazachlor, Azinphos-ethyl, 1,3-Dichlorobenzene, 2-Methyl benzenamine, Bentazone, 1,4-Dichlorobenzene, Methyl naphthalene, Biphenil, 2,4-Dichlorocresol, 2-Methylbutane, 2,2-Bipyridine, 2,5-Dichlorophenol, Monuron, Bis(2-Ethylhexyl)Phthalate, 3,6-Dichlorophenol, Napthalene, Bromacil, 2,4-Dichlorophenoxy, Nitrobenzene, Bromodichloromethane, Dieldrin, m-Nitrophenol, p-Bromophenol, Diethylphthalate, o-Nitrophenol, Butylbenzene, 2,4-Dinitrocresol, p-Nitrophenol, Calcium Hypochloryte, 2,4-Dinitrotoluene, Ozone, Carbofuran, 2,6-Dinitrotoluene, Parathion, Chlorine, Diuron, Pentachlorophenol, Chlorine dioxide, Endosulfan, Propazine, Chlorobenzene, Endrin, Simazine, 4-Chloro-2-nitrotoluene, Ethylbenzene, Terbutryn, 2-Chlorophenol, Hezachlorobenzene, Tetrachloroethylene, Chlorotoluene, Hezachlorobutadiene, Triclopyr, Chrysene, Hexane, 1,3,5-Trimethylbenzene, m-Cresol, Isodrin, m-Xylene, Cyanazine, Isooctane, o-Xylene, Cyclohexane, Isoproturon, p-Xylene, DDT, Lindane, 2,4-Xylenol

A carbon filter can remove the following chemicals Effectively –

Aniline, Dibromo-3-chloropropane, 1-Pentanol, Benzene, Dibromochloromethane, Phenol, Benzyl alcohol, 1,1-Dichloroethylene, Phenylalanine, Benzoic acid, cis-1,2- Dichloroethylene, o-Phthalic acid, Bis(2-chloroethyl) ether, trans-1,2- Dichloroethylene, Styrene, Bromodichloromethane, 1,2-Dichloropropane, 1,1,2,2-Tetrachloroethane, Bromoform, Ethylene, Toluene, Carbon tetrachloride, Hydroquinone, 1,1,1-Trichloroethane, 1-Chloropropane, Methyl Isobutyl Ketone, Trichloroethylene, Chlorotoluron, 4-Methylbenzenamine, Vinyl acetate

Acetone, Methylene chloride, Acetonitrile, 1-Propanol, Acrylonitrile, Propionitrile. Dimethylformaldehyde, Propylene, 1,4-Dioxane, Tetrahydrofuran, Isopropyl alcohol, Urea, Methyl chloride

All water purification methods have their limitations, the key is to establish what is present in your water supply and what contaminants require removal before deciding upon your purification method. Quite often, multiple systems are required in order for you to achieve the water quality you are looking for. A carbon filter is unable to remove microbial contaminants such as viruses and bacteria, hard water minerals such as calcium and magnesium, and fluoride or nitrate.

Who needs a carbon water filter?

Industries that often use a carbon water filter are :

  • Food and beverage production
  • Aerospace
  • Borehole
  • Pretreatments before Reverse Osmosis
  • Polishing for treated effluent
  • Pretreatment before water softening
  • Ground water purification

Does activate carbon have a shelf life?

No. As long as the activated carbon is kept dry and out of the way of any contaminants which it may adsorb, it can be stored indefinitely. To maintain the shelf life of the carbon, you also need to be sure that the protective packaging is not compromised in any way and to also be mindful of possible rodent attacks.

What is a Filox R filter?

 Filox R is a trademark name for a substance that is used as a filter media. Filox R is made up of 80% manganese dioxide. Its unique formation allows for an enhanced performance, superior oxidation and filtration capacity. The performance of Filox R out performed Greensand and Brim.

What is Filox R used to remove?

Primarily, Filox R is used to remove Ion, hydrogen sulfide and manganese. Filox R is particularly effective at removing manganese due to its high levels of manganese dioxide (75-85%) significantly out performing other manganese removal systems that contain significantly less – Greensand -3% and Birm 1%.

What should i consider before installing a Filox R filter

The first thing to be aware of is that a little bit goes a long way. it is also important to know that contaminants and minerals present within your permeate water has a substantial effect on how the Filox R performs. it is essential that you test your permeate prior to ordering and designing your water treatment system. Filox R is capable of removing the following contaminants without any other chemical interventions.

Manganese – 3.0ppm

Ion – 15.0ppm

Hydrogen Sulfide – 7.0ppm

If higher levels of removal are required, Filox R can be paired with additional treatments such an oxidising agent, chemical regeneration or tannin removal.

How long will a Filox R Water Filter last?

As with any filter, it is essential that it is properly maintained and serviced regularly to ensure all filtration media and the filters moving parts remain is a good working condition. IWE offers great servicing packages or serving on an ad hoc basis. more information regarding servicing can be found here IWE Servicing. With this in mind, a properly maintained water filter can last indefinitely and Filox R, which correct maintenance will last between 5-10 years.

How do i correctly maintain Filox R?

it is essential for the successful removal of contaminants that Filox R is maintained correctly and the main contributing factor to this is ensuring regular backwashes. Backwashing Filox R will agitate the bed releasing the contaminants and allowing them to be washed away to drain. Filox R is quite a heavy media so therefore requires a good flow to successfully break through and wash the bed. if the bed is not successfully backwashed, it will quickly become fouled and the system will no longer be effective.

How often should i back wash my system?

The answer to this question depend on your incoming flow rate and the chemical characteristics of you water. Because Filox R is particularly effective, it loads up significantly more that other forms of media. because of this, daily backwashing is recommended to ensure optimal performance

What if i require a more robust removal of Manganese, Ion and hydrogen sulphide?

Additional treatments are available to enhance the performance of Filox R. These treatments include using oxidisers and chemical regeneration. By introducing oxidising agents such as oxygen, chlorine, ozone, hydrogen peroxide and potassium permanganate, the Filox R will become super oxidised allowing it to perform better. Adding such agents will not have any kind of negative impact on the performance quality or the lifespan of Filox R, if anything, it will improve the performance significantly and also the lifespan.

Will i require any other finishing treatments after using Filox R

This all depends on the chemical make up of the permeate flow before using Filox R. To discuss this further, its best to talk to one of our water treatment technicians in order to establish what system will meet your exact requirements. The types of media that are commonly used in conjunction with Filox R are Tannin removal media, mixed bed resin, or a carbon filter.

Is Filox R tolerant to chlorine?

Yes. unlike many other filter medias, Filox R copes perfectly with chlorine. In fact, it actually helps the performance significantly helping to keep it clean and helps with the oxidation of sulphide and iron.

Are there any downsides to Filox R?

Despite Filox R far exceeding the performance of comparable medias, There are several downsides to using the product that buyers may need to be aware of.

Firstly, Filox R is very dense and therefore very heavy. this is quite problematic when it comes to shipping as the cost can soon mount up.

Filox R is rather a lot more expensive than comparable filter medias. Almost three times the price of Birm

The filter housing may also have to be made more robust to accommodate the powerful backwash required. this may also prove to be more costly that other comparable medias.

What is pH and what pH should my water be?

 pH – or Potential of Hydrogen is a term used to determine the acidity or alkalinity of a liquid substance.

The Ph scale ranges between 0 – 14. 0 = Acid and 14 = Alkaline. A natural pH is 7. Pure water has a pH of 7.

Water Filters pH Scale Diagram

From 0 – 14, each stage goes down in acidity and up in alkalinity considerably. A pH of 7 is 10x more acidic than a pH of 6 and a pH of 5 is 100x more acidic than a pH of 7. Because of this, when determining and/ or correcting the pH of your water, the slightest increment or decline by even 0.1 can greatly effect the quality of your water and depending on your application, could cost you dearly. A pH correction filter will help you to regulate your water and will protect you from corrosion of pipework, staining of appliances and undesired taste of the water.

Why might i need a pH filter?

pH water filters are commonly used in industry. Particularly where there is a lot of water treatment equipment or water appliances such as boiler houses. A pH correction system would be required when water is supplied from a borehole or natural spring at the pH of the water is usually lower than 7. A pH filter would be used to protect the pipework, equipment and tanks from premature corrosion. Acidic water eats away at metals and will eventually cause holes to form. If you have copper pipes, copper within the water will be elevated and this can cause adverse effects on your health.

How will the pH filter work?

The unit will be fitted as close to the source of the water supply as possible to ensure that the untreated water has as little opportunity as possible to be exposed to your water pipes or equipment. Permeate water will pass through the unit and through the pH correction media. Once the water has passed through the media, it will then pass back through the main water line.

The desired flow rate is approximately 5 gallons per minute. This flow rate allows for the permeate to be in contact with the filter media long enough to ensure the water is effectively neutralised.

The pH correction media comprises of crushed and processed limestone. The compound used and recommended by IWE is Magnadol (otherwise known as Magnesium Carbonate) – this can be found by clicking here – IWE Magnadol. The Magnadol dissolves into the water before passing through a filter, the natural alkalinity of the Magnadol will re mineralise the water and raise the pH to a safe and desired pH of 7. Because there is a high calcium level prevalent within Magnadol, there will be an increased water hardness by approximately 50ppm

Periodically, the pH neutralising filter will backwash, which alters the way in which water circulates through the water filter. The water within the backwash cycle flows in from the inlet straight down the centre riser tube, up through the Magnadol bed and away from the control valve to drain. The next phase in a pH neutralising filter regeneration cycle is rinse. The water in a rinse cycle of the pH neutralising filtration system passes just as it does in service, down through the composite pressure vessel and Magnadol filter media and up via the centre riser tube through the neutralising filter control valve and finally, to drain. The pH neutralising filter then returns to its normal service position.

In a domestic setting, A pH filter will reduce the green staining that can occur around taps and your bath and basin.

Do pH correction systems require cleaning?

There are two types of heads available for pH correction units. The first and most simple unit is a non-backwash head. This head allows the water to come in, pass through the media and then to flow out as remineralised water. This system is effective and is the cheeper of the two options. the downside to a non backwash head is that the Magnadol ( magnesium carbonate) can become compacted and clogged and form itself into a solid block. This is because a constant water flow will find its natural channels through the magnadol and because there is no reverse agitation the media will be like able to remain loose and absorbent.

The second head available for a pH correction unit is a backwashing head. This system is slightly more sophisticated and the more expensive of the two but the back washing feature will ensure the magnadol is regularly cleaned and agitated, prolonging the life of the magnadol and ensuring the system is working as effectively and efficiently as possible.

Will the pH correction system require any maintenance?

As with any water treatment equipment, it is essential that it is serviced by a water treatment engineer at least one a year to ensure the system remains fully functional and the components remain in good working order. Industrial Water Equipment offer a competitive service package and also offer one off servicing where required. More information can be found here – Equipment Servicing

How often does the Magnadol (magnesium carbonate) require replacement?  

This does really depend on your rate of permeate flow and your usage and the acidity of the water. Accurate details regarding sizing of required equipment can be established by calling Industrial Water Equipment and speaking to a water treatment technician on – 01629 55839.

Our Fleck Nitrate Removal filters utilise a Nitrate selective resin to remove unwanted Nitrates in water supplies.

A 7 day 24 hour timer attached to the water control valve controls a time-controlled water softener. The time controlled water softener regenerates to what you have programmed the regeneration times to. This can me a minimum of once per week and a maximum of once per day. The usual time for regenerating a time controlled water softener/filter is 3pm when the water usage is at it’s lowest. The time of regeneration on a duplex time controlled softener is not as important as on a simplex model as the water to service is not interrupted.
The voltage of the timer is usually 12v and new timer-controlled softeners are supplied with a 240v to 24v transformer. /particulate removal capacity, between regenerations, will vary with units. Softeners/filters with small capacities must regenerate more often. Your daily softening/filtering need depends on the amount of water used daily in your household and the hardness/fouling levels of your water. To determine your daily hardness removal need, multiply daily household water use (measured in gallons) by the hardness of the water (measured in grains per gallon).

Example: 400 gallons used per day X 15 grains per gallon hardness = 6,000 grains of hardness must be removed daily.

Meter controlled softeners and water filters work by having a water meter or turbine on the outlet side of the softener or filter control valve. The meter or turbine sends a pulse to the counter within the control valve and when a preset value is reached the softener or filter will go into a regeneration cycle.
Most duplex water softeners and filters will be meter controlled as they gain the maximum capacity from the resin or filter media and makes the system more efficient. Unlike the time controlled units the resin or filter mediawill only regenerate once they are exhausted. You cannot preset a time for regeneration as you can for time controlled systems so meter controlled systems are rarely used in domestic situations.

A simplex water softener/filter consists of one vessel containing ion exchange resin or filtration media retrospectively,once the ion exchange resins/media are exhausted. the water softener/filter will go into the regeneration sequence. During the regeneration sequence which takes around 2 hours there will be no water passed through the softener or filter to service.

If the water softener/water filter is time controlled it is possible to set the regeneration time to 3am when there is usually no requirement for water but if the water softener/filter is a water meter controlled unit it is more difficult to gauge at what time the softener/filter will regenerating.

If a continuous supply of softened or filtered water is required it is usual to install a duplex water softener/water filter.

A Duplex water softener/filter consists of two vessels containing ion exchange resin, Once the first column of resin has exhausted and goes into regeneration the second column goes into service.

This maintains soft/filtered water to service at all times. Duplex water softeners and water filters are usually water meter controlled but in some cases can be time clock controlled.

Siata control range or Fleck control range?

How to choose which valve suits your application.

In our opinion both valves perform very reliably and set the industry standard for water treatment control valves.

The biggest factor in choosing between each of them is personal preference. However there are small differences in the construction materials and slight differences in flow characteristics.

Below we have the main elements of valve selection and once you have specified which valve you prefer you can check the characteristics of the unselected option at the end of the selection guide.
