ABSTRACT:
A water treatment arrangement is provided in which water is given a reduced pH by a first catalyst and then is caused to flow over a second catalyst that changes nitrates, nitrites, phosphates, salts and other contaminants from reactive to nonreactive form. The first catalyst may be palladium and the second catalyst an alloy containing copper, tin, nickel and zinc. The first catalyst prevents precipitants from coating the second catalyst and also increases the supply of oxygen in the water. Preferably, a third catalyst, also palladium, is included downstream of the second catalyst. The first and third catalysts include longitudinal vanes having louvers to present a large surface area and create turbulence. The second catalyst is a tubular assembly with ribs and grooves also to create turbulence and removal of the stagnant boundary layer from the catalyst's surface. The catalysts are in an end-to-end abutting relationship within a housing of corrosion-resistant material.
