These products prevent the formation of solids (such as iron oxy-hydroxides, hardness scales, or biomass) and are added continuously, at ppm levels to recovered groundwater prior to other treatment operations. A variety of formulations are designed for specific types of common fouling. These blends may include sequestrants, dispersants, crystal modifiers and reducing agents. Redux formulations are designed to be highly effective, yet can be discharged to the environment with treated groundwater.
