Precipitant station

Phosphate binding (also called phosphate precipitation) is a natural process. In areas with very iron-rich groundwater, a reddish-brown discoloration of the water can be observed. This is due to the iron-II ions dissolved in the water. The addition of oxygen causes the iron-II ions to oxidize. They become water-insoluble iron-III ions. These iron-III ions are positively charged and, if present, form a bond with negatively charged phosphates. Nutrient flakes are formed, which sink to the bottom and sediment.

This process can be controlled using precipitants. In addition, the iron salts used have a stronger binding force and thus allow the phosphates to be removed more sustainably. Coagulants are used globally in water treatment.

Since the use of a precipitant station is very individual, these components are only sold after prior detailed consultation and planning.
