Abstract
Agents are used as cleaning agents and also as agents to purify the water in water treatment plants. The agents are a mixture of phosphates and fatty acid salts. Precipitation agents are used such as, polyvalent metals. The pH is adjusted. Flocking agents can be used to increase the rate of separation. The purified water is removed after precipitation.
