ABSTRACT:
This invention combines the functions of filtering and softening water in a unitary system utilizing a single apparatus. The combined system first oxidizes and filters sulphur, manganese and iron and then softens by an ion exchange process using sodium chloride as the exchange chemical. The filtering process removes precipitated concentrations of iron, manganese and hydrogen sulphide gas through the use of a manganese treated zeolite material known as "Manzite". This system, provides a combined operation utilizing one water treating tank containing a filter substance such as the manganese treated zeolite, which draws from an associated chemical holding tank and a brine tank in performing the described functions in a single apparatus.
