75-07: Recovery of Chromate from Cooling Tower Blowdown by Ion Exchange Resins Materials Laboratory studies indicate that molybdateDuring the past several decades, chromate based corrosion inhibitors were widely used in open cooling water recirculating systems. In 1971, the Japanese Government, however, adopted a regulation which limited the discharge of toxic matter including hexavalent chrome to public waters. Factories employing cooling systems were forced to reduce chromates to less than 0. 5 ppm as Cr^6+ or replace chromates to other types of corrosion inhibitors; however,
