The typical way to create a supersaturated condition is by adding ,caustic soda, to increase solution pH. However, because ,wastewater, normally has a considerable buffering capacity because of the presence of organic acids and inorganic carbonates, significant base addition is needed in order to increase the bulk solution pH to a certain level that would induce CaP precipitation.
