In natural waters phosphorus occurs as orthophosphate (PO43-), polyphosphate (P2O74-; P3O105-; P3O93-; P4O124-) anions and in trace amounts as organically bound phosphorus. A large proportion of the phosphorus in surface water orginates from municipal waste effluents, largely from detergents. Orthophosphates applied to agricultural land as fertilisers are carried into surface waters with run off. Organic phosphates are formed primarily by biological processes. Phosphorus is essential to the growth of organisms and can be the nutrient that limits the primary productivity of a body in water. The phosphorus promotes the growth of algae in nuissance quantities for the water system. Phosphates also occur in bottom sediments and in biological sludges, both as precipatated inorganic forms and incorporated into organic compounds.

Using the TOPHO Analyser, the efficiency of a waste water treatment plant can be controlled and allows adjustments to the process in function of the P-signal.
