78-12: Chromate Handling Systems for Cooling Tower Blowdown Cooling Tower Conversion

78-12: Chromate Handling Systems for Cooling Tower Blowdown Cooling Tower ConversionChromate based inhibitors have been widely used in cooling systems for corrosion control for many years. However, recent environmental legislation has increased restrictions on industrial chromate discharge. Hexavalent chromate can be removed from cooling tower blowdown by either reducing it chemically or electrochemical1y1 2 to the trivalent form or by ion exchange and reuse in the system.

Matrai Power Plant in Hungary decided in 1990 to replace all former "solutions" with one "Quality Set" for the different performances

Based on the test information on the current condition and the original design stresses

This can have high economic consequences due to a loss of thermal exchange

back-to-back configurations create more recirculation than in-line

conducted in several regions

The tower was upgraded in April '88 during the scheduled plant outage of three weeks

cooling ranges and approaches

By using the Cool Puck product as an additive to traditional biocide treatment the mitigation and prevention of biofilms was concluded in an industrial cooling tower system

Increasing the heat transfer coefficient reduces the necessary heat exchanger size

or heat exchanger to a cooling tower
