4. Stage: Membrane processes / Nanofiltration During the fourth and final cleansing stage, membrane and filter processes are utilised. In part, this purification phase is combined with the chemical processes of precipitation and flocculation.
Supplementary treatment could possibly be desired for the advantage of the inhabitants. One these kinds of instance is definitely the fluoridation of water, the place fluoride is additional to water.

Nitrogen compounds remove the important oxygen in the water and can even lead to fish to die when discharged into water bodies.
From the U.S., chlorination is the most common indicate of disinfection. Chlorination might be followed by dechlorination to avoid deteriorating ecological health of your obtaining stream along with the production of carcinogenic by-goods.eleven
In acquiring countries and in rural regions with small inhabitants densities, sewage is frequently read more dealt with by many on-website sanitation systems and never conveyed in sewers. These systems contain septic tanks connected to drain fields, on-web site sewage systems (OSS), vermifilter systems and plenty of more. Alternatively, Highly developed and comparatively expensive sewage treatment plants might incorporate tertiary treatment with disinfection And perhaps even a fourth treatment stage to remove micropollutants.[7]
