82-01: Biofouling Control in Recycled Cooling Water With Bromo Chloro Mechanical Draft Towers

82-01: Biofouling Control in Recycled Cooling Water With Bromo Chloro Mechanical Draft TowersRecycled cooling water can contain very high levels of organics, creating a potentially significant Biofouling problem on heat transfer surface. A system in which all treated process waters were added to the cooling water system, and the cooling water was recycled through a sidestream softener was studied. A variety of Biofouling monitoring systems were evaluated; as were control chemicals.

and USA test procedures for this type are not considered adequate

Control of soft deposits in cooling systems is an important objective of water treatment programs

using recycled water with high ammonia contents for cooling water make-up adopted a new economical stabilized halogen technology to solve bio-treatment problems

The recommendations are applicable for Natural and Mechanical Draft cooling towers

Historically Bromine based non-oxidizing biocides have been an industry standard with occasional Isothiazolin or Gluteraldhyde dosage

electricity consumption

including the use of an open circuit cooling tower coupled with a plate & frame heat exchanger or the use of a closed-circuit cooling tower

The impact of measuring key actives in cooling water treatment is demonstrated through improved system performance and control

The plume was impacting yard operations at an adjacent Operations Center

Data is presented on a unique
