77-18: Cooling Tower Salinity Optimization via Sidestream DesalinationAt the 97th Winter Annual Meeting of the American Society of Mechanical Engineers in New York City, Dow Chemical presented a paper on alternative designs for zero discharge power plants. The results of that paper showed that side streams softening followed by Electrodialysis (ED) had the lowest capital investment of several different processes for achieving zero discharge conditions.

Samples of the cooling water were collected

The benefits of proper control are measurable and translate to improved system efficiency and reliability

chemicals were metered into the cooling water in proportion to blowdown water flow

we will comment on some promising developments in wood treatment for the future

building plants at low cost has been the priority rather than the performance

Common causes of system failure unrelated to water treatment include: (a) Operational Issues

BPA does not build dams or powerplants

and it will give a procedure to be used to compare the relative performance of the fills

combined with structural analysis

This paper will focus on research efforts

A useful bibliography of valuable references on the subject is also included

This paper covers the CTI Standards and how to utilize them properly in specifications
