Aquapure HQ is an excellent, all-purpose reducing agent for wastewater treatment. It may be used in the classic sense to reduce hexavalent chrome to trivalent. It may also be used to reduce excess oxidizers such as oxygen, peroxide, persulfate, chlorine or hypochlorite permanganate. As a liquid, it may be metered or pumped. Depending upon the application, the use of ORP to control additions may be desirable.
