Surface Water

NClear engineers have defined an ideal solution for remediation of surface water bodies.

Lakes, ponds, rivers, estuaries, and bays are subject to high levels of phosphorus concentration as a result of land runoff or discharges from other point sources. This can result in eutrophic effects such as toxic algae or hypoxia.

NClear’s treatment technology uses a patented calcium-silicate nanocrystal technology (TPX™) to efficiently and permanently sequester phosphorus both in the water column and in the sediment. Our remediation process addresses the root cause (phosphorus) and not the symptom (toxic algae). 

TPX™ crystals are engineered to optimize dissolved inorganic phosphorus removal. The phosphorus binds to the crystals and is permanently sequestered. The inert crystals with the bound phosphorus settle in the sediment, making the phosphorus permanently unavailable as a nutrient in the water column and will continue binding soluble phosphates that may become released from the sediment. TPX™ nanocrystals are non-toxic and have been verified to meet US EPA acute/chronic toxicity and reproductivity standards (EPA-821-R-02-012). NClear recently contracted with the Florida Department of Environmental Protection (FDEP) to demonstrate our surface water remediation technology to remove phosphorus from Lake Apopka, Florida. The full report on the Lake Apopka demonstration project can be found here.
