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

Community Level. A public/private water rehab facility aims to make water safe to consume and pleasant to taste, while being sure that there exists enough water to deliver the demands of the city.

Raw, untreated water arises from an underground aquifer (via wells) or surface streams just like a river or lake. It flows or perhaps is pumped with a rehab facility. As soon as it’s there, water is treated beforehand to take away debris - like leaves and silt. Then it goes thru a series of treatment processes, which include disinfection and filtration using chemicals or physical processes, eliminating microorganisms that can cause diseases. When the treatment methods are completed, water flows out by having a system of pumps and pipes, which is often referred to as distribution system.

There is a slight difference water treatment process at various places, using the technology with the plant and water needed to be processed, however the fundamental principles are mostly the same.

Coagulation / Flocculation. In the coagulation state, liquid aluminium sulfate or alum, and at times polymer, lies in untreated/raw water. This mixture causes tiny dirt particles in water being fastened together or coagulated. Then, collections of dirt particles join together to produce bigger, heavier particles Known as flocs - which are easily removed through filtration/settling.

Sedimentation. When water and floc particles feel the course of treatment, they flow into sedimentation basins where water moves slowly, letting heavy floc particles dip towards the bottom. Floc collected about the lowermost area of the basin is known as sludge. This holds through pipes to achieve the drying lagoons. The sedimentation state is not included in Direct Filtration and thus, the floc is taken off through filtration.

Filtration. Water experiences a filter that will remove water particles. Filters contain layers of gravel and sand, plus other cases, crushed anthracite. Filtration gathers the suspended water impurities and improves the efficacy of disinfection. Filters are cleaned often by means of backwashing.

Disinfection. Before water adopts the distribution system, it can be disinfected to ensure that bacteria that produces diseases, parasites and viruses is eliminated. Chlorine is used because it a great in disinfecting and residual concentration to protect from possible biological contamination seen in it of water distribution.
