Plants for Biological Phosphorus Removal
Phosphorus stimulates plant growth (eutrophication) in streams, lakes, rivers, and in the ocean. A large part of the phosphorus which is discharged into the receiving waters derives from wastewater. Due to increasing eutrophication problems all over the world, the demand for phosphorus removal from wastewater is increasing. Biological phosphorus removal is a process which can be fully or partly used for the solution of the problem. It will sometimes be necessary to combine the process with chemical precipitation of some of the phosphorus. Sludge from treatment plants with biological phosphorus removal will be well-suited as fertilizer if it is not overloaded with metals or organic toxins which are poisonous to the environment.
