What is Wastewater Treatment and Process of Wastewater ...

“Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can be used for other purposes. The treatment process takes place in a wastewater treatment plant

STAGE ONE: SCREENING Screening is the first stage of the wastewater treatment process. Screening removes large objects like diapers, nappies, sanitary items, cotton buds, face wipes, and even broken bottles, bottle tops, plastics, and rags that may block or damage equipment. Special equipment is used to remove grit that gets washed into the sewer.

Wastewater treatment plants are designed to process the raw sewage prior to its discharge to reduce its organic content, oxygen demand, and pathogenic content. This is accomplished by utilizing treatment processes that remove the waterborne pollutants directly (primary treatment) or that convert them into bacterial cells (secondary treatment). With biological treatment processes, the same . 32 ...

11.09.2019  Membranes used in wastewater treatment and reuse, too, are vulnerable to biofilm fouling. Formation of biofilm on filtration membranes and resultant clogging of pores (biofouling) is one of the most stubborn problems faced by such operations. In some applications, 85ºC sanitization of membranes is used for chemical-free maintenance. In a membrane aerated biofilm reactor (MABR), however ...
