We are water treatment plant manufacturers in Mumbai. Water Filtration is done in order to remove colloidal and suspended matter remaining after sedimentation and to remove the bacterial load.
The process of filtration usually consists of allowing the water to pass through the thick layer of sand or porous material which retains coarse impurities on its surface and in pores.
The apparatus used for filtration is called a filter and the porous material that fills the filter is known as the filtering medium.

Types of Water Treatment Filter:
- Single flow closed pressure filter
- Horizontal flow pressure filter
- Dual media filter
- Inflow Sand Filter
- Mechanical Filter- Radical Filter- Multiple Chamber Filter
The water compounds are classified into three categories: suspended solids, colloidal particles (less than 1 micron), and dissolved substances (less than several nanometers).
The coagulation-flocculation processes facilitate the removal of SS and colloidal particles.
It’s used in the final stage of solids-liquids separation: settling, flotation, or filtration.
Coagulation is the destabilization of colloidal particles brought about by the addition of a chemical reagent called a coagulant.
Activated Sludge Process- This is the most versatile biological oxidation process employed for the treatment of wastewater containing dissolved solid, collides, coarse solids, and organic matter.- Sewage from the sedimentation tank enters into the aeration tank.
Activated Sludge Process- This is the most versatile biological oxidation process employed for the treatment of wastewater containing dissolved solid, collides, coarse solids, and organic matter.- Sewage from the sedimentation tank enters into the aeration tank.
Here 20 – 30% of active sludge is mixed. The mixture is aerated and mixed in the tank for about 4 to 8 hours.
An efficient aeration for 3 – 6 hours is occupied for sludge while for industrial waste 6 – 24 hours of aeration is required.
The microorganism oxidizes organic matter, in the presence of an abundant quantity of oxygen in the aeration tank.
Sewage is allowed to settle in a secondary sedimentation tank. This settled sewage has undergone aeration and has active microorganisms.
So some portion of activated sludge is recalculated into the aeration tank.
