PRO POLY-4

Poly-4 sequesters iron and manganese to reduce or eliminate iron staining in potable water, irrigation systems and other areas where unsightly iron staining is to be prevented. Poly-4 also helps prevent or retard corrosion through the water system, and can be used in the treatment of potable water. This formulation holds the dissolved iron in solution, keeping the water clear, and thus preventing iron staining.

Applications
Pro-Poly is applied through a chemical feed pump. The pump and solution tank are installed downline from the well pump. Pro-Poly is normally fed at a rate of 1 pound (1.5 cups) per 40,000 gallons of water. Feed rate should be increased to 1 pound per 20,000 gallons of water in above-normal iron and corrosion water supplies. Follow the procedure for injecting Pro-Poly solution into the water system as specified by the chemical feed pump manufacturer or supplier. The product is compatible with the majority of chemical feed pumps.

Features and Benefits
Pro-Poly is a unique blend of polyphosphates containing special inorganic inhibitors designed to react quickly with iron molecules found in difficult, high-iron water. This highly resistant film containing synergistic zinc and phosphate provides the protective mechanism to control scale and corrosion. Lime scale is a mineral deposit that forms when hard, bicarbonate waters are heated. Pro-Poly prevents lime scale by keeping the hardness particles separated so they do not precipitate and form deposits when the water is heated. Pro-Poly effectively controls corrosion by forming a thin protective film on all the metal surfaces of the water system. It will not break down in hot water systems (up to 212 F).
