Dirty muddy water is caused by dirt and mud in suspension in the water. To remove these suspended solids in water like dirt, fine sand, etc; we use sediment filters. Most of the domestic water filters to remove cloudiness from water are made of plastic and inside these plastic filter housing is the actual filter element, called a filter cartridge which removes the turbidity or cloudiness from water. Cartridges over the period gets clogged when it captures the dirt from the water and so water filter cartridges must be replaced at regular intervals, otherwise the flow through the water filter gets blocked.

In Pre Filter most common cartridge size is 2.5 inches in diameter and 10 inches in length with 5 microns porosity. PP (Spun Polypropylene) cartridges are the preferred cartridges since they last longer and also because they are more reliable in filtering to the desired sizes. Other cartridge filters like the Yarn cartridges cannot guarantee filtration to a particular particle size but it's service life is more. Within the Purifier Cabinet, Inline Sediment Filter used consists of 1.75 inches Diameter & 8 inches length.

Passing water through an activated carbon water filter purifier improves the taste of drinking water and also makes water safe to drink by removing Odour, Colour, Chlorine, Organic Impurities & Few Pesticides. So activated carbon is a very efficient purifier of water and is widely used in water filter purifiers.

Activated carbon is an extremely porous material that attracts and holds on its surface harmful chemicals by a process known as adsorption.

Activated carbon in water filter purifiers has a limited ability to adsorb contaminants from water, and so the activated carbon in water filters should be changed when it has been depleted and cannot purify water anymore. The pore structure of the activated carbon gets filled or saturated with the adsorbed pollutants and it cannot adsorb any more. At this stage the activated carbon will start rejecting some of the previously adsorbed pollutants back into the water flowing over it. This is called 'breakthrough'. When this happens, the concentration of pollutants in the treated water will be higher than in the raw water being treated. The activated carbon filter cartridge must be replaced well before this happens.

Activated Carbon water filter purifier does not remove microbes and dissolved inorganic chemicals like Nitrates, Fluorides and hardness in water. One of the big disadvantage of activated carbon water filter is that it can be a breeding ground for micro-organisms on the surface of the activated carbon filter media, especially when there is no running water over the activated carbon in the water filter, like when it is not being used for a long time, some of the organic chemicals adsorbed by the activated carbon becomes the meal for these bacteria.

The surface area within the pores of Activated carbon is huge, one gram of activated carbon can have surface areas of 500 to 1500 meter square depending on the Classification of the Activated Carbon. The quality of Carbon is decided by its Iodine Value. We use 1000 to 1100 IV Silver Activated Carbon in our Purifiers.

We counter the bacterial growth on the surface of activated carbon by impregnating the activated carbon with nano-silver particles. Silver ion is a bactericide and will be helpful in preventing these bacterial growth. Ultra Violet (UV) after activated carbon filter is another way of preventing the germs growing on the activated carbon to pass through your drinking water.
