Wastewater Treatment

Wastewater treatment chemicals produced by Chemetall provide a variety of solutions to combat any wastewater situation. With Chemetall you will enjoy minimized sludge production, reduced man-hour requirements, improved effluent quality, greater consistency, enhanced water-recycling capabilities, and reduced cost — all while meeting your discharge limitations.

Chromate Reduction

Dispoz Aid 1 is a dry, powdered material developed for treating spent chromate solutions prior to disposal. It converts the hexavalent chromium into the easily precipitated trivalent form. Required by Federal, State and Local regulations, the trivalent chrome is precipitated out of solution with Dispoz Aid 2.

Heavy Metals Removal

Dispoz Aid 2 is a dry, powdered product intended for use in removing heavy metals from spent or reduced acid solutions, including trivalent chromium, copper and iron; it also removes phosphates and fluorides.
Liquid Dispoz Aid HM precipitates and removes many heavy metals such as zinc, iron, nickel, copper, cadmium, lead and aluminum from spent solutions that require disposal.

Spent Emulsions Treatment

Mildly alkaline Dispoz Aid EB effectively splits spent oil or solvent emulsions in one easy step.

Cationic Coagulants

Our products neutralize ionic charge differentials to form a "microfloc" of neutralized solids that display enhanced coagulation, floc structure, size and density. Treated wastewater displays enhanced metal removal and reduced turbidity. Chemetall's cationic coagulants are more effective in reducing sludge volume than traditional inorganic coagulants such as calcium chloride and ferrous sulfate.

Enprox 8533 is a proprietary blend of two cationic coagulant substrates that have been polymerized with a medium weight cationic polymer. It is specially formulated to absorb oil and grease and turn them into a dense, dewatered floc matrix.
A combination of an iron-based coagulant and a high molecular weight cationic polymer, Enprox 8423 is highly reactive and very aggressive in the neutralization and coagulation of suspended wastewater particles.
Enprox 8407 is a concentrated cationic coagulant solution whose neutral composition provides solution charge neutralization and coagulation in final neutralization tanks as well as in acid and alkaline solution tanks.
Enprox 8412 is a proprietary aluminum/calcium solution with an all-inorganic composition that makes this product compatible with membrane-based filtration systems.
Enprox 8340 is a concentrated, low molecular weight, cationic, liquid metal precipitant agent employed for the reduction of metal ions from industrial wastewater and process water applications. ENPROX 8340 can be employed as a metal reduction agent for both batch and continuous water treatment systems. It also functions as a final polishing agent in any type of treatment system.

Anionic

Chemetall's anionic polyelectrolytes rapidly produce a dense floc, of large size and agglomeration, that provide for immediate settling in clarifiers and holding basins.

Enprox 8110 is an anionic polyelectrolyte in emulsion form. Enprox 8110 will react quickly at a pH between 7 and 11 to flocculate metal hydroxides. A rapidly formed dense floc, of large size and agglomeration, provides for immediate settling in clarifiers and holding basins. Enprox 8110 is very effective as a sludge-conditioning agent.
Enprox 8439 is an anionic polyelectrolyte. Enprox 8439 will react quickly at a pH level of 7 to 10 to flocculate metal hydroxides. A rapidly formed dense floc, of large size and agglomeration, provides for immediate settling in clarifiers and holding basins.
Enprox 8440 is an anionic polyelectrolyte in hydrated form. Enprox 8440 will react quickly at a pH level of 7 to 11 to flocculate metal hydroxides. A rapidly formed dense floc, of large size and agglomeration, provides for immediate settling in clarifier and holding basins.

Defoamants

Concentrated Enprox 8784 is a siloxane-based formulation and is non-ionic in charge composition.
Non-ionic Enprox 8617 is a silicone-based concentrated defoaming agent which is non-ionic in charge composition. Enprox 8617 will not alter wastewater treatment characteristics due to its neutral composition. Enprox 8617 has been successfully implemented for foam.
Enprox 8477 is a concentrated defoaming agent, consisting of a blend of surfactants. Enprox 8477 will not alter wastewater treatment characteristics due to its neutral composition. When applied in cooling water treatment programs, Enprox 8477 will not alter treatment additives of anionic or cationic nature.

pH Adjustment

For neutralizing wastewater before discharge, rely on Chemetall's pH adjustment products. They make no biochemical oxygen demands on water and are phosphate free.

Enprox 702 is a liquid, inorganic acid that neutralizes alkaline waste prior to discharge. Other uses are: for lowering pH of recirculated industrial cooling water to control alkalinity and scale; for regulating pH of solution being treated with Oakite Dispoz Aid 1. Enprox 702 makes no biochemical oxygen demands on water and is phosphate-free.
Enprox 714 is a liquid alkaline product designed for neutralizing acidic solutions prior to disposal. It may also be used to regulate the pH of water in air conditioning units, water cooling towers, waste effluent systems, evaporative condensers and other similar water systems. Enprox 714 may be used to control the pH level of solutions being treated with Dispoz Aid 2. It makes no biochemical oxygen demands on water and is phosphate-free.

Dispersants

Enprox 8030 is an integrated, acrylate-based water dispersant that contains aggressive copolymers with excellent hardness and iron suspension properties.

Water Care

Enprox 8124 will react quickly at a pH level of 7 to 11 to flocculate metal hydroxides. A rapidly formed dense floc, of large size and agglomeration, provides for immediate settling in clarifiers and holding basins. Enprox 8124 is a very effective as a sludge conditioning agent. Flocculation is rapid, of large size, and agglomeration, for immediate settling. Enprox 8124 has a wide pH operating range to ensure flocculation is complete and of high density. Metal hydroxide is tightly bound to the polymer lattice structure resulting in a high tolerance for mixing and shear resistance.
