75-07: Recovery of Chromate from Cooling Tower Blowdown by Ion Exchange Resins Materials Laboratory studies indicate that molybdate

Laboratory studies indicate that molybdate may be effective when used in conjunction with cathodic and other anodic inhibitors

A formalized and verifiable quality system can translate into an improved product for the Cooling Tower customers regardless of the product purchased

This paper will present current laboratory and field fouling evaluation methods

to be used directly in the manipulated osmosis step

The paper has been presented before and reviewed by the Cooling Tower Institute and approved as a valuable contribution to cooling tower literature

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,
