Large Scale Sewage Treatment

	Large Scale Sewage Treatment Municipal Bodies - Municipal plants are equipped for a mechanized sewage treatment that handles massive amounts of waste and garbage generated daily. A simplified view of such a waste treatment facility. The overall process can be divided into three steps: the primary, secondary and tertiary treatments. These different treatments to sewage depend on the quality of the effluent deemed necessary to be achieved to permit the maintenance of acceptable water quality.
Primary treatments rely on physical separation procedures to lower the BOD; secondary treatments rely on microbial biodegradation to further reduce the concentration of organic compounds in the effluent; and the tertiary treatments use chemical methods to remove inorganic compounds and pathogenic microorganisms. Municipal treatment plants are not capable of dealing with industrial wastes containing toxicants, such as heavy metals.
