We help water managers improve water quality worldwide by controlling phosphorus release from the sediments and soluble P within the water column of lakes and reservoirs, using the novel product Phoslock.


Phoslock Europe has applied Phoslock to more than 300 water bodies across Europe, with applications resulting in reduced in-lake phosphorus concentrations and improvements in water quality which, in many examples, has led to a more biodiverse aquatic community.


Applications have been undertaken on drinking water reservoirs, lakes, ponds, urban ponds, impounded rivers, water bodies used for recreational activities (swimming, fishing, water-based sports, golf and leisure), water bodies with environmental designations (e.g. sites of Special Scientific Interest, Special Areas of Conservation, Ramsar sites and water bodies that come under the remit of the European Water Framework Directive).
