In specified instances, excessive algae in the raw water may end up in algal growth blocking the sand filter even more down the treatment process. In such predicaments, chlorination is used rather than, or Besides, aeration to eliminate the algae, termed pre-chlorination.
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) can be a sort of wastewater treatment which aims to eliminate contaminants from sewage to supply an effluent that is definitely appropriate to discharge on the encompassing atmosphere or an supposed reuse software, therefore preventing water air pollution from Uncooked sewage discharges.[6] Sewage incorporates wastewater from households and businesses And perhaps pre-addressed industrial wastewater.
