92-04: Update of Cooling Tower Ozonation at an Organic Chemical Manufacturing Analysis Method

92-04: Update of Cooling Tower Ozonation at an Organic Chemical Manufacturing Analysis MethodBeginning in September 1975, ozone replaced chlorine in a crossfire induced draft cooling tower at a Henkel Corporation, Emery Group organic chemical manufacturing facility (Building 60) in Cincinnati. A year later a sister chemical plant (Building 68) in Cincinnati adopted ozone for its cooling tower. The results from these two applications were first reported in an address delivered to the International Ozone Association in June of 1981. This paper

Results indicate that elemental content in drift water (mineral residue) may not be equivalent to the content in the recirculating cooling water of the tower

was the Water Quality Act of 1965

The drift rate and spectrum of droplets have been measured with all existing techniques

This preparation is based on the knowledge of what the system contains

The paper will discuss several modifications that can be made to existing crossflow and counterflow towers to enhance overall energy savings

and service standards based on key performance indicators

and tentative standards for fire protection

Chemical additives to the cooling water (osmotic agent) are retained within the process

“Marketing” of some treatment chemicals emphasizes their “biodegradability”
