07-19: Efficient One Step Phosphorous and Suspended Solids Removal from Cooling Tower Water Chemistry

07-19: Efficient One Step Phosphorous and Suspended Solids Removal from Cooling Tower Water ChemistryReuse of municipal wastewater for cooling tower makeup is increasing in popularity, as it can meet multiple requirements imposed by environmental, regulatory, political and economic factors. The ability to efficiently and economically remove suspended solids and nutrients in a single step is realized by using a gravity driven, downflow, continuous operation, graded media filter. Suspended solids and phosphorous removal at levels greater than 90% is

there is considerable opportunity to reduce fan energy costs the remaining 98% to 99% of the year

the model cooling towers offer a relatively simple and meaningful method for evaluating cooling tower biocides in a realistic lab test

The relative effective of the oxidant (work value) must be taken into account to achieve automated control

and evaluation of fouling risk

and community awareness compel industry to consider water reuse

is irreversible and often results in premature and costly wood replacement

need for preservative treatment and review what is available in lumber treat­ment today

Operational data will be presented explaining how these stresses were managed using a comprehensive treatment

Evaporative pre-cooling of air cooled heat exchangers provides the thermodynamic advantages of water cooling towers with the reduced maintenance requirements of air cooled heat exchangers

O&M concerns

Actual cooling tower water is used as the test medium to establish proper biocide treatment in recirculating systems
