Industrial wastewater treatment
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product After treatment the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment Most industries produce some wastewater Recent trends have been to minimize such production or

What are the Three Stages of Wastewater Treatment?
There are three main stages of the wastewater treatment process aptly known as primary secondary and tertiary water treatment In some applications more advanced treatment is required known as quaternary water treatment This stage deals with part per million to part per billion levels of contamination and often involves oxidation or fine filtration processes

Wastewater treatment
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 acceptable impact on the environment or reused for various purposes (called water reclamation) The treatment process takes place in a wastewater treatment plant (WWTP) also referred to as a Water Resource Recovery

POLICY GUIDANCE MANUAL ON WASTEWATER
Poor sanitation and wastewater management in developing countries leads to the contamination of fresh water sources and is a major cause of disease and death and affects also the health of eco-systems 80-90 percent of all wastewater generated in developing countries is discharged directly into surface water bodies without any treatment
Activated Sludge Process Explained
Activated Sludge Process The Activated Sludge Process (ASP) is a sewage treatment process in which air or oxygen is blown into raw unsettled sewage to smash the solids and develop a biological 'soup' which digests the organic content and pollutants in the sewage These plants do not have a primary settlement chamber which is the chamber that needs emptying by tanker on a regular basis
