Water Filters – Clack Simplex

 

Clack Carbon Water Filters

Granular Activated Carbon (GAC) filters are an excellent choice for removal of chlorine, taste, odour or organics (bone charcoal will also reduce some heavy metals). Coconut, coal, bone or wood based are available. Flow is based on dechlorination, reduce to 20% for colour. Click here to view range.


Clack Turbidex Water Filter

Clack Turbidex Water Filters. Turbidex is a unique natural clinoptilolite ore that has many outstanding advantages over common filter sands used for sediment reduction. Turbidex is very angular, rough surfaced and has microporous void spaces as small as 3 microns. This creates a surface area over 100 times greater than sand and can reduce suspended solids down to 5 microns or less (sand filters down to about 40 microns). Turbidex prevents the rapid build up of head loss and binding associated with sand filters and allows longer periods between back washes. Because of its high porosity and hydrophilic nature, Turbidex can operate at much higher flow rates than conventional sediment filters. Click here to view range.


Sand Filters

Clack Sand Water Filters are needed when the water supply is cloudy or turbid. The easiest way to remove the particles is by passing the water though a media where the particles get stuck allowing clear water to flow through. The particles can be periodically backwashed away to drain. Sand is the ideal media for this. Only the highest quality, triple washed 0.4 to 0.8mm size water treatment grade sand is used in these systems (typically reducing particles to about 40um). A sand filter Ag mix gives filtration down to about 20um and Turbidex can reduce particles down to 5um. Click here to view range.


Clack Multimedia Water Filters

AquaMulti and AquaMulti BIO are multifunctional water filtration medias that consist of five high quality ingredients (ion exchangers and adsorbents). It is an effective one step eliminator of the 5 main problems (hardness, iron, manganese, organic and ammonia) in domestic and industrial applications. AquaMulti decreases the level of organic matter up to 50% (AquaMulti Bio up to 80%). The media works with many water supplies (mains, borehole and well), regardless or iron form (colloidal, ferric or organic), pH level, hardness, hydrogen sulphide, organic content. However it can foul and high bicarbonate causes concreation. Click here to view range.


Clack Birm Water Filter

Birm is a relatively inexpensive material which can be used for iron and manganese removal by oxidation. It requires a pH of 7 or more for iron removal and 8 for manganese removal (it uses dissolved oxygen in the water to oxidise the metal). As it acts a catalyst it is not consumed so Birm doesn’t require regenerating or topping up. Birm also has the advantage of acting as a filter, removing turbidity. If the pH of the water is too low than correction may be required. Media life expectancy is 2 to 3 years. Click here to view range.


Clack Filox R Water Filter

Clack Filox R Water Filters can be used for Iron and Manganese reduction by oxidisation. Like Birm the pH needs to be controlled and there needs to be oxygen present. Filox can tolerate chlorine and has a higher flow rate than Birm and Manganese Dioxide. Click here to view range.


Clack Crystal Right Filters

Crystal Right works by an iron exchange process which reduces iron, manganese, ammonia and hardness and can increase low pH all in a single process. The minimum pH requirement is 6. The regeneration process is exactly the same as that used in a water softener and requires regeneration with salt. There are 2 types of Crystal Right. CR100 is used where the pH is over 6 and when the pH is low often increases the pH. CR200 is used where the pH is 7 or above (has a higher capacity). Click here to view range.


Clack Nitrate Removal Water Filter

Clack Nitrate reduction water filters. The legal limit for Nitrates is 50mg/l. A Nitrate reduction system is made up of a vessel filled with Nitrate selective resin with a multi-port valve on the top. As the water passes through the resin the Nitrate is trapped. Periodically this Nitrate needs to be removed by regenerating with salt. As the Nitrate levels vary from month to month a time based regeneration system is recommended. Smaller systems can be cabinet based, larger ones come with a separate brine tank to hold the salt. Click here to view range.


Clack pH Correction Water Filter

Water with a pH below 7 is acidic and corrosive. Raising the pH will neutralise the water, removing the metallic taste and pipe corrosion, and can also reduce any iron or manganese contamination. The backwashing head has the advantage of remixing the media and removing any debris or iron / manganese. By backwashing, the unit stops the media compressing and stops it going hard.

Clack Colour Reduction Water Filters

Tannins & organic compounds in upland water give water a yellow tint. In highland areas where water runs off peat the water can be virtually brown. Organic scavenging systems use resin to hold these organics which are periodically backwashed away with brine. Click here to view range.


Clack Hydrogen Sulphide Water Filter

Hydrogen Sulphide (H2S) is a gas which if dissolved in water smells like rotten eggs. The easiest way to remove the smell of small amounts is to aerate the water or pass it through carbon. In conventional carbon filters the carbon gets saturated and regularly needs replacing. In this system the H2S is sprayed through a layer of air held in the top of the vessel oxidising the gas vastly improving the capacity of the carbon reducing the need and cost of carbon replacement.

Clack Arsenic Removal Water Filter

Arsenic is found naturally in many parts of the UK and Ireland and with the lowering of the European drinking water standards for arsenic it’s removal is vital. The contaminated water passes through robust granular Bayoxide media developed for Seven Trent Water. As the water travels through the media the arsenic is absorbed and removed to a level below the drinking water standard. This treatment is a very cost effective way of removing arsenic.
