TAILIEUCHUNG - WASTE WATER TREATMENT AND REUTILIZATION

The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues | WASTE WATER -TREATMENT AND REUTILIZATION Edited by Fernando S.
