Water treatment - Wikipedia

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.Water treatment removes contaminants and undesirable components, or reduces their concentration so that

Ultrafiltration - an overview | ScienceDirect Topics

One strategy to combat this problem is using the MF hybrid system. The performance of hybrid MF membranes has been investigated by numerous researchers. An aluminum-based coagulant was employed as the pretreatment process, and the results showed that the permeate flux and water quality were enhanced in comparison with MF filtration alone [161].

Water Treatment Plant - an overview | ScienceDirect Topics

Treated raw water is mixed with potable water and pumped to the boiler feedwater treatment system. The system is designed to remove 99% of the dissolved minerals and provide high-purity water to the boiler. The mixed water flows through a reverse osmosis plant operating at a recovery of 80% and an average salt rejection of 95%.

Lime-Soda Water Softening Process and its Advantages Notes

A combination of lime and soda ash, along with coagulant and flocculant chemicals, is added to raw water to promote a precipitation reaction. This allows softening to take place. To prepare feed to a demineralization system. The lower levels of calcium, magnesium, and especially silica reduce the ionic loading on the demineralizer when warm
