For Domestic Use

The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.

Across the world, there continues to be huge volumes of wastewater pumped directly into rivers, streams and the ocean itself. The impact of this is severe – aside from the damage to the marine environment and to fisheries it can cause, it does little to preserve water at a time when many are predicting that a global shortage is just around the corner.

As it stands this method of disposing of wastewater – any form of water that has been contaminated by a commercial or domestic process, including sewage and byproducts of manufacturing and mining – is largely an issue in developing nations, particularly across Asia and India.

• Pre-chlorination for algae control and arresting biological growth
• Aeration along with pre-chlorination for removal of dissolved iron and manganese
• Coagulation for flocculation or slow-sand filtration
• Coagulant aids, also known as polyelectrolytes – to improve coagulation and for thicker floc formation
• Sedimentation for solids separation that is removal of suspended solids trapped in the floc
• Filtration to remove particles from water
• Disinfection for killing bacteria viruses and other pathogens.
