Effective Phosphorus Removal with Unique Porosity
Filtralite Nature is a fine-grained filter material, made of expanded clay, with a unique porous structure that creates optimal conditions for water to flow through the filter bed and maximizes the contact area for phosphorus binding. This design supports effective and long-lasting phosphorus removal. Phosphorus is removed through precipitation at elevated pH and chemical binding. Filtralite Nature also removes suspended solids and heavy metals.
When the filter material reaches its phosphorus saturation point, it can be replaced. The spent material can also be reused as fertilizer or soil conditioner, as long as it complies with local regulations for heavy metals and bacteria
