Industrial Wastewater Treatment

Industrial wastewater contains various types of inorganic as well as organic dissolved solids. The various methods employed for removing inorganic matter are : evaporation, dialysis, ion exchange, adsorption, reverse osmosis etc. The organic dissolved solids are generally removed by biological methods in which the microbes including bacteria and protozoa, metabolize the biodegradable organics, converting them into CO2, water and energy for their growth and reproduction. There are many types of biological treatments for treating organic matter i.e., activated sludge processes, rotating biological contactor, trickling filter, contact stabilization, lagooning, oxidation pond and anaerobic digestion.
