precipitation (chemical)
The process of producing a separable solid phase within a liquid medium; represents the formation of a new condensed phase, such as a vapour or gas condensing to liquid droplets; a new solid phase gradually precipitates within a solid alloy as a result of slow, inner chemical reaction; in analytical chemistry, precipitation is used to separate a solid phase in an aqueous solution.

freshwater degradation
Pollution immediately or eventually involves the hydrological cycle of the earth, because even pollutants emitted into the air and those present in the soil are washed out by precipitation. Water is considered polluted when it is altered in composition or condition so that it becomes less suitable for any or all of the functions and purposes for which it would be suitable in its natural state. This definition includes changes in the physical, chemical and biological properties of water, or such discharges of liquid, gaseous or solid substances into water as will or are likely to create nuisances or render such water harmful to public health, safety or welfare, or to domestic, commercial, industrial, agricultural, fish or other aquatic life. It also includes changes in temperatures, due to the discharge of hot water. (Source: WPR)

physicochemical purification
Used to concentrate waste brines and to remove solid organics and ammonia from aqueous solutions. Physical treatment consists of reverse osmosis, dialysis, electrodialysis, evaporation, carbon, adsorption, ammonia stripping, filtration, sedimentation, and flocculation. Chemical treatment consists of ion exchange, neutralization, oxidation, reduction, precipitation, and calcination.
