78-01: On Stream Evaluation of General and Pitting Corrosion Rates in Cooling Materials

78-01: On Stream Evaluation of General and Pitting Corrosion Rates in Cooling MaterialsA program was initiated to investigate the general and pitting corrosion rates in cooling water systems a. t the plant sit. e, using potentiodynamic tech niques. Metal electrodes are exposed to various corrosion inhibitors and examined by electrochemical techniques and by microscopic examination.

According to the new formula

Marley cooling tower in 1998

These facilities are being installed on ever decreasing smaller plots that causes equipment installation close to property lines

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

The evolution

The department tested alternative biocides and is now using an effective low cost biocide

15-ton pultruded structural fiberglass modules

A multi-functional cooling water treatment chemical is applied to a cooling tower system using a diffusion-based technology utilizing patented coated tablets

plus that on the waterside

sacrificial corrosion methods

Very little full-scale information is available to indicate the magnitude of the effect of tip clearance on cooling tower performance

and other good practice limitations
