Lake and Pond Restoration - Chemical Free Phosphorus Filtration System

Our PhosFilter Nutrient filtration system assists in pond and stream protection, lake, stream and watershed restoration projects. The system captures phosphorus with a design based on an innovative "side-stream" filtration system that utilizes a proprietary phosphorus removal filtration media.

The PhosFilter system utilizes a chemical free phosphorus removal design. The PhosFilter system is both cost-effective and compact, capturing phosphorus and other pollutants as well.

Florida Everglades Restoration R&D Project  — Our team was involved in a multi-year water pollution filtration project funded by a Grant from the US Army Corp of Engineers and the South Florida Water Management District (SFWMD). The environmental restoration R&D project’s purpose was to identify a cost-effective stormwater treatment technological system capable of reducing nutrient loadings in stormwater canals spread across a cattle ranch that flows into Lake Okeechobee, ultimately flowing into the Florida Everglades. Nutrients, specifically phosphorus, have been responsible for declining water quality in the Everglades and have been targeted to be monitored and controlled by both Federal and State pollution control regulations. Our team designed and installed a large filtration system comprised of a single large rainwater reservoir/pond to store and contain stormwater high in phosphorus prior to entering two filtration ponds containing proprietary filtration media know today as UltraPhosFilterTM. This technology was proven effective where approximately 90% of TP was removed, from up to 5.0 mg/l to 0.5 mg/l or less.
