Water Technology
At Cirkel, sustainability and responsibility for our environment are taken literally.
Sustainability and environmental responsibility are integral components of CIRKEL's corporate philosophy. This is evident in the conscious selection and conservation of natural raw materials – lime, sand, and water – as well as in close collaboration with experienced partners in the environmental and water technology sectors. Modern process management, the original – i.e., primary – production for the application area, and continuous quality control ensure the consistently high properties of CIRCOSIL® for our customers. The calcium silicate hydrate (CSH) CIRCOSIL® is already successfully used as a multifunctional mineral in numerous water technology applications.
CIRCOSIL® is used:
as a crystallization seed in phosphate removal
in wastewater treatment plants for recovering dissolved phosphates
for reducing magnesium ammonium phosphate (MAP) deposits
in industrial wastewater treatment
for reducing eutrophication in lakes and ponds
in the P-RoC process
in the SIMPhos process
in phosphate absorption plants
as an aid for heavy metal precipitation
