In wastewater treatment, all wastestreams consist of solid and liquid components all of them. Chemical methods of wastewater treatment take advantage of two types of properties: (1) the chemical characteristics of the pollutants, regarding their tendency to react with, or interact with, treatment chemicals; and (2) the chemical characteristics of the products of reaction between pollutants and treatment chemicals, regarding their solubilities, volatilities, or other properties that . Other biological methods It has extremely thin separation layer with a pore size of 3 to 100 . treatment methods are also used, it is still difficult to meet the need for further development in the treatment of sewage from the rapid development of cities. Wastewater treatment is a process in which the solids in wastewater are partially removed and partially changed by decomposition from highly complex, putrescible, organic solids to mineral or relatively stable organic solids.
