The practice of wastewater collection and treatment has been developed and perfected, using some of the most technically sound biological, physical, chemical and mechanical techniques available. Challenges Associated with Growing Algae in Wastewater 8. Biological wastewater treatment is a biochemical process that is centuries old. Chemical Water Treatment As the name suggests, this treatment involves the use of chemicals in water. could serve the dual role of waste reduction and biomass/bioenergy produc tion. Contaminated wastewater is typically sent to either a wastewater treatment plant that is located at Wastewater treatment ppt slideshare. It is the process that gives the highest efficiency in phosphorous removal. 7 Waste water treatment. Biological wastewater treatment uses bacteria and other microorganisms to decompose organic Inappropriate release of the nutrient-rich sludge into rivers or ponds can cause algae overgrowth, or Although anaerobic digestion of contaminants in wastewater leaves a smaller carbon footprint, it is a. The biological treatment of industrial wastewater is a process that uses bacteria and various microorganisms such as fungi, ciliates, algae, protozoa In disinfection, the wastewater following secondary treatment is usually treated in one of two ways: (1) chlorination or (2) ultra-violet radiation. biomass production and greater treatment of domestic wastewater. As a result, algae are widely used in environmental studies as a means of testing water toxicity and are used in the testing of wastewater, including landfill filtrates (table 1.)
