PO4-P - What is Phosphate?

Phosphate measurement is an important water quality parameter used to indicate water pollution. Phosphate may be determined using on-line instrumentation or by using portable/laboratory water analysis. The continuous testing of water to determine the phosphate comprises a typical final effluent monitoring system. Phosphate measurement may also be performed using on-line instrumentation within drinking water process control applications.

The Chemitec Colortec is an on-line colorimetric analyser using recognised measurement technology, to continually report the (dissolved) ortho-phosphate concentration, with a maximum measurement range of 40mg/L PO4. The sample may be prepared using the PPM membrane filtration system to 0.45 micron) or alternatively the Paper Band filtration system filtering to approximately 20 micron.
