Raw water from all sources can be treated for suspended solids, turbidity & colloidal particles using clarification systems.

TEIL as the leading manufacturer offers the widest range of raw water & treatment systems.

Our designs & offerings are customized to project requirement and can best meet challenges of varying inlet loads, low space & area for installation, low power requirements & minimized sludge generation.

We have designed & installed over 500 plants of varying capacities working effectively for over three decades.

The treatment system comprises of flash mixer & flocculation zones where suitable chemicals are dosed for pH correction & flocculation.



Water Treatment Processes

Clean, safe water is vital for every day life. Water is essential for health, hygiene and the productivity of our community.

The water treatment process may vary slightly at different locations, depending on the technology of the plant and the water it needs to process, but the basic principles are largely the same.

This section describes standard water treatment processes.

Coagulation / Flocculation

During coagulation, liquid aluminium sulfate (alum) and/or polymer is added to untreated (raw) water.

When mixed with the water, this causes the tiny particles of dirt in the water to stick together or coagulate.

Next, groups of dirt particles stick together to form larger, heavier particles called flocs which are easier to remove by settling or filtration.


As the water and the floc particles progress through the treatment process, they move into sedimentation basins where the water moves slowly, causing the heavy floc particles to settle to the bottom.

Floc which collects on the bottom of the basin is called sludge, and is piped to drying lagoons.

In Direct Filtration, the sedimentation step is not included, and the floc is removed by filtration only.


Water flows through a filter designed to remove particles in the water.

The filters are made of layers of sand and gravel, and in some cases, crushed anthracite.

Filtration collects the suspended impurities in water and enhances the effectiveness of disinfection.

The filters are routinely cleaned by backwashing.
