TPX™ Nanocrystal Technology

NClear’s TPX™ nutrient removal technology has a base structure of CaxSixO2.83x (OH)0.33x, and is an engineered chemical compound consisting of nanocrystals of calcium silicate hydrates (C-S-Hs) and amorphous soluble chemicals designed to create an optimal environment to promote Hydroxyapatite when applied to an aqueous solution rich in phosphates. The chemical composition of TPX™ is non-toxic and when applied to surface waterbodies, is similar to the chemistry of sand found in the sediment of healthy surface waterbodies. TPX™ has been verified to meet US EPA acute/chronic toxicity and reproductivity standards (EPA-821-R-02-012), and also meets US FDA Generally Regarded as Safe (GRAS) guidelines. TPX™ nanocrystals are engineered for the optimal shape, size, purity, and chemical ionic charges to create a strong attraction to soluble reactive phosphorus (SRP). The nanocrystals convert SRP to a solid crystal structure once bound to the nanocrystals and thereby permanently remove the SRP from aqueous solutions. See TPX FAQ

Product Application

  • The amount of TPX™ needed for dosing is determined based on the waterbody source’s initial P concentration level, as well as the desired P removal level
  • Water chemistry modeling and a laboratory jar-testing analysis is initially conducted to determine the most effective TPX™ dosage amount and application type/location
  • TPX™ can be applied in either a dry (powder) or slurry (liquid) delivery method
  • TPX™ residuals can be removed by clarification, filtering, or skimming (DAF applications)
