TPX™ is ideally suited for use in Industrial Wastewater applications

TPX™ is a patented (US 9,434,624 & US 9,440,868), non-toxic nanocrystal chemical compound (base structure of CaxSixO2.83x(OH)0.33x) consisting of calcium silicate hydrates (C-S-H) and amorphous soluble chemicals designed to create an optimal environment to promote Hydroxyapatite when applied to an aqueous solution rich in phosphates. 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. TPX™ is the only economical treatment solution that does not pose any toxicity or safety concerns.

Value Proposition

Wastewater plants are increasingly subject to stricter discharge limits for P. This is particularly true for industrial wastewater plants, especially animal processing plants. TPX™ nanocrystals are the ideal treatment solution for these applications.
  • TPX™ has been verified to meet US EPA acute/chronic toxicity and reproductivity standards (EPA-821-R-02-012), as it contains no hazardous, toxic, or harmful elements.
  • Due to its unique chemistry, TPX™ is the most efficient medium on the market for phosphate removal. Phosphates are adsorbed onto the TPX crystals, thereby converting the P from a soluble form to a solid state, where it can effectively be removed through common filtration, clarification, and precipitation methods, including the primary practice in animal processing: dissolved air floatation (DAF).
  • TPX™ acts as a very hydrophobic coagulant, which helps to produce a thicker and drier sludge. Because TPX™ complies with US FDA Generally Regarded as Safe (GRAS) guidelines, the fats, oils and grease (FOG) skimmed off the DAF does not need to be sent to a landfill, as it can be utilized as a protein source. Competing coagulant products containing aluminum and ferric are toxic and therefore DAF skimmings that contain these metal salts are not able to be rendered for edible protein.
  • TPX™ has the inherent ability to boost alkalinity and pH levels in treated wastewater, thereby reducing or eliminating the need for additional caustic chemicals.
TPX™ Imaging (20kX Magnification)
The strength of the bond between a sorbent (e.g., clay mineral) and a sorbate (e.g., phosphate) depends on a variety of factors. These factors include the structural configuration or geometric shape, including surface area of the solid phase and the zero point of charge of the solid phase involved (which is pH dependent). In general, the larger the surface area, coupled with the strength of the electrical charge, the more it will attract and cause an ionic bond to an oppositely charged and suspended molecule. The stronger the opposite electrostatic charges are, the stronger the ionic bond. In the case of weak (or partial) ionic bonds, the more easily they can be broken apart by competing dissolved ions or a change in the aqueous phase pH. Sorption characterized by a strong ionic bond typically requires extreme chemical changes in the water, such as a very significant pH level change, which rarely occurs naturally. TPX™ was developed with these considerations in mind to optimize its sorption characteristics with the phosphate anion.

TPX™ has the strongest binding characteristics at ambient pH levels of any sorbent we have tested – including aluminum and ferric salts.

Nclear conducted a series of side stream pilot evaluations in conjunction with Fieldale Farms to demonstrate their TPX™ technology at their Cornelia Ga facility. The full report on the Fieldale Farms project can be found here.
