Water treatment plants produce a wide variety of waste products as well as safe drinking water. These residuals may be organic and inorganic compounds of liquid, solid, and gaseous form depending on the source of raw water and the type of treatment processes, commonly, coagulation/filtration, precipitate softening plant, membrane separation, ion exchange, and granular activated carbon.
