86-13: Diol Technology: A Unique Non-Heavy Metal Treatment Approach FillsThis new treatment approach provides results comparable to traditional chromate programs over a wide variety of water qualities and system conditions. This paper presents the results of this treatment approach applied at Ciba Geigy's St. Gabriel, Louisiana Plant. Corrosion rates at the plant have been less than 0. 4 mpy on carbon steel coupons, while eliminating the fouling previously experienced due to inorganic loading. The program takes advantage

environmentally friendly isothiazolone biocide has been developed

The final affluent is 1

total residual chlorine

a polymer is used along with ferric sulfate in the lime/soda ash softening process in a reactor-type clarifier

Therefore using calcium hypochlorite had a high overall cost

This paper discusses the design and application of composite cooling tower couplings

starters and wiring

and the Plant has been in continuous operation since early in 1952

A year later a sister chemical plant (Building 68) in Cincinnati adopted ozone for its cooling tower

and icing damage

providing iron oxide solubility and dispersion

Data is presented to illustrate the long-term durability and serviceability of this species
