Water Treatment Concepts

Helping the quality water involves disinfection plus purification of untreated surface and ground water.

Community Level. A public/private water treatment facility aims to produce water safe to consume and pleasant to taste, while also making sure that there exists enough water to produce the requirements of the community.

Raw, untreated water emanates from an underground aquifer (via wells) or surface ponds being a river or lake. It flows or perhaps pumped into a treatment facility. The moment it really is there, the water is treated beforehand to take away debris - like leaves and silt. It experiences some treatment processes, including disinfection and filtration using chemicals or physical processes, eliminating microorganisms that can cause diseases. After the therapy is completed, water flows out by having a system of pumps and pipes, which are often called the distribution system.



There is a slight difference water treatment process at various places, based on the technology with the plant and water should be processed, but the fundamental principles are typically precisely the same.

Coagulation / Flocculation. With the coagulation state, liquid aluminium sulfate or alum, and also at times polymer, is placed in untreated/raw water. This mixture causes tiny dirt particles in water to get fastened together or coagulated. Then, collections of dirt particles join together to create bigger, heavier particles Known as flocs - that happen to be easily removed through filtration/settling.

Sedimentation. When water and floc particles glance at the course of treatment, they flow into sedimentation basins where water moves slowly, letting heavy floc particles dip for the bottom. Floc collected on the lowermost the main basin is recognized as sludge. Which i mentioned above through pipes to succeed in the drying lagoons. The sedimentation state is not incorporated into Direct Filtration and thus, the floc is removed through filtration.

Filtration. Water goes through a filter intended to remove water particles. Filters contain layers of gravel and sand, plus other cases, crushed anthracite. Filtration gathers the suspended water impurities and enhances the efficacy of disinfection. The filters are cleaned often by way of backwashing.

Disinfection. Before water goes into the distribution system, it’s disinfected to ensure that bacteria that creates diseases, parasites and viruses is eliminated. Chlorine can be used because it an effective in disinfecting and residual concentration to protect from possible biological contamination seen in it water distribution.
