Water Filters – Fleck Simplex


Water Filters – Fleck Simplex

Our Fleck Simplex range is available in a various different flow rates between 0.6 -7.8 M3. Fleck systems are renowned for being simple and easy to use as well as being quick and easy to assemble and install.

One positive aspect about these systems is that they function using a single moving part (a piston) making the likelihood of failure very low but easy to diagnose and resolve.

The systems are also recognised as being very affordable with with a large product range to suit all requirements and budgets.

Parts for fleck systems are simple to find, we stock them all here at Industrial Water Equipment.


Fleck Simplex Water Filter Information

There are various different types of media available for Water Filters. Some forms of media are more effective at removing specific contaminants therefore choosing the correct Water Filter media for filtration is very important.

Activated Carbon

Is ideal Water Filter for the removal of colour taste and odour. This black powdery substance is also ideal for the removal of Chlorine, Ozone, Organics and metals. Activated carbon is also highly effective at removing a vast range of chemicals. These types of filters are commonly used before Reverse Osmosis systems due to the fact that mains water is dosed with chlorine which is particularly destructive to RO membranes.

These filters are also commonly used within food production for the removal of colour taste and odour as well as any chemicals or contaminants within the water that could have an effect on the food.

Activated carbon comes from a number of different origins. These are bone, coconut shell, wood, peat and petroleum based residue. These substances are put through an activation process which involves applying steam. This process leaves the carbon with a much higher internal surface area accessible to vapour and liquid making it ideal for Adsorption to take place.

Multimedia Filtration

Multimedia or (MMF) Water Filters consist of a collection of four different filtration methods combined into one single unit. This single filter is commonly placed before a Reverse Osmosis system to ensure the removal of any contaminants that are likely to scale, foul or chemically attack the membranes.

The main reason for using a MMF is to reduce turbidity. A MMF can remove particulates of between 10-20 microns. If further filtration is required, the effectiveness of a MMF can be increased to between 5-10 microns by using a coagulant.

The four medial layers of a MMF are as follows :

Media 1

Consists of gravel and is placed at the bottom as it is the heaviest and largest particle this layer is also used as a support layer.

Media 2

Consists of a 2mm filter sand/ garnet and is placed directly underneath the finer layer of sand.

Media 3

Consists of a fine filter sand/ garnet and is placed directly underneath the anthracite.

Media 4

Consists of Anthracite (coal) and although it is the largest particle, it is also the lightest and it therefore placed on top.

The media within the water filter is arranged in this way to ensure larger particles are removed at the beginning allowing for finer particles to pass through and be removed by the following layers of media.

Filox R

Filox R water filters are made up from Manganese Dioxide and are most effective at removing Iron, Hydrogen Sulphide and manganese. Filox R filters are reported to vastly outperform other manganese removal medias due to the fact that it is made up from 80% manganese dioxide making it the more favourable option.

Filox R is capable of removing the following contaminants without any further chemical interventions

Manganese – 3.0ppm

Iron – 15.0ppm

Hydrogen Sulphide – 7.0ppm

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

pH Correction Media

pH Correction Water Filters are commonly used for various different applications within industrial settings but can also be found in residential settings. pH correction is most commonly required when the water supply comes from a borehole or natural spring. Borehole water usually has a pH lower than the desired pH of 7 and can be as low as 6 pH. If left uncorrected, this can cause a multitude of problems with pipework, tanks, boilers and other water treatment equipment not to mention the effect it can have on your industrial production. Even a 0.1 increase or decrease in pH can greatly effect the quality of your water and depending on your application, could cost you dearly.


Birm Water Filters are ideal for the removal of Iron and Manganese but also have the capability of filtering many other contaminants and chemicals such as Arsenic, Radium and Hydrogen Sulphide. Birm is particularly long-lasting. The process of filtration doesn’t erode or affect the performance on the Birm meaning there is no need for regular top-ups. The media within a Birm Filter is likely to last up to 5 years before it becomes exhausted. Birm is a non-chemical substance which is a great advantages as many companies do not like to have chemicals on site where possible.

Birm is commonly used as a pre-treatment filter for applications such as pulp mills, paper mills, tanneries, textile plants, dye houses and launders.

Nitrate removal

Nitrate removal works in a very similar way to water softening using Ion Exchange resin. With nitrate removal however, a different polymer Ion Exchange resin is used that is specifically targeted to attract nitrates and sulphates, replacing them with Chloride ions. Once the bed is exhausted, the system kicks in to regeneration much like water softening. A Nitrate removal filter is required if nitrates in your water supply exceeds 10ppm. This often occurs when when water is sourced from a borehole or in farming communities where farmers use fertilisers. If nitrates in the water supply exceed the recommended maximum, the water can be harmful to consume, particularly for babies, young children, the elderly of for those who’s immune system has been compromised.
