Sand filter

Sand fltration is a process in which the treatment of the water is realized by the 'porous' nature of a sand layer which traps particles present in water. Sand flters are widely used in water purifcation and remove suspended matter by a completely different mechanism. A sand flter, makes use of sand to filter water. The water to be purifed slowly sinks through the sand of the sand filter, leaving the dirt particles from the water behind in the fine pores of the sand. The unfiltered water is distributed in the top of the sand flter and will slowly sink through the filter bed. This flter bed consists of sand, gravel or another filter medium. The small pores ensure that the dirt particles are not able to pass through and retain the dirt particles.

Activated Carbon Filter

The Activated carbon Filters are designed to remove free chlorine, organic matter, odor and Color present in the raw water and waste water. Due to its high degree of micro porosity, activated carbons provide a huge surface area. Activated carbon filter operates through adsorption. Adsorption is directly related to the surface area of the media. This great surface area furnishes a huge adsorption area for organic as well as chlorine molecules to attach themselves. Various grades of carbon are available for specialized treatments.

Iron Removal Filter

The Iron Removal Filters are designed to remove the Excess Iron content present in the Water. Iron can often be detected visibly in water or by staining on plumbing fixtures. Iron filtration systems operate on the principal of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or undissolved state. Once the iron is converted to ferric state, it is precipitated on a filter bed.

Water Softening Filter

The presence of excess minerals such as calcium and magnesium make water hard. Hard water leads to a variety of problems such as foul plumbing, Scaling, galvanic corrosion, dry skin, and brittle hair. Hard water is converted into soft water by exchanging hard salts of calcium and magnesium with sodium using an ion-exchange process. This is done with the help of resin beads charged with sodium salts, which attract hard salts and convert them into soft salts.

Ultra Filtration (UF)

Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.

Multigrade Filter

Multigrade filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles.
