77-18: Cooling Tower Salinity Optimization via Sidestream Desalination Cooling Tower Conversion

77-18: Cooling Tower Salinity Optimization via Sidestream Desalination Cooling Tower ConversionAt 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.

and gives a procedure to determine maximum recirculation to be expected for any given operating condition

On many field erected cooling tower projects

which of course is the primary material in many condenser tubes

Argon National Laboratories under CRADA demonstrated the use of ED/RWEDI while Nalco developed scale inhibitors for the integrated solution

Biofouling control has always been a difficult task for cooling tower treatment programs

discharge criteria

and modern high heat transfer procedures illustrated with actual hands-on field examples

drift requirements as low as

but theses recommendations can also be modified for seasonal storage

field-erected towers can only be tested on-site once built

Special considerations must be addressed in regard to thermal expansion and contract when fiberglass pipe is anchored

which have led to a novel new product
