SCHAEFER PRECAphos® has been developed specifically to make phosphate precipitation more efficient and environmentally friendly.

Rather than using harmful acids or alkalis, as found in conventional liquid precipitants, we use high-purity calcium compounds in combination with special iron salts.

As a result, SCHAEFER PRECAphos® is a completely new phosphate precipitant that also optimizes biological wastewater treatment.

Being a powder and a non-hazardous material, it is easy to transport. It can be dosed as bagged goods directly on site at small wastewater treatment plants. In case larger quantities are required, we provide suitable rental silo facilities and delivery of SCHAEFER PRECAphos® in bulk in silo trucks.
