Excess nutrient input into waterways poses a major ecological threat and leads to a range of negative environmental impacts. Controlling nutrient levels, most importantly phosphorus, in stormwater and surface water runoff is a key issue for sustainable development and environmental management.

Phosphorus Retentive Filter Media is designed for use in new and existing detention basins and bio-filters to remove phosphorus, improving water quality and reducing nutrient inputs into waterways and groundwater.

Phosphorus Retentive Filter Media is free draining and is designed to hold its nutrient stripping properties for a minimum of 50 years.
