Numerous sewage treatment technologies have already been produced, largely applying biological treatment processes. Structure engineers and conclusion makers need to have to take into account complex and economical conditions of each and every alternate When selecting an appropriate know-how.[eight]: 215 Frequently, the principle criteria for variety are: ideal effluent excellent, anticipated building more info and running expenses, availability of land, Electrical power necessities and sustainability facets.
