Large or Small Process Cooling Water Applications are Perfect for AMSA BCP® Chemistry
Both open loop and closed loop process industrial cooling systems will have cleaner surfaces, allowing more efficient heat exchange and cooling when AMSA BCP® chemistry is included in the chemical treatment program.
AMSA BCP® 1000, 2000, & 3000 series products have been successfully used to provide penetration and dispersion of organic deposits in order to clean and maintain clean surfaces in large and small process cooling systems. BCP® chemistry in liquid formulations can be slug dosed, pumped semi-continuously, or added to an all-in-one drum formulation. Solid slow release DTEA II® tablets provide continuous treatment to control fouling, corrosion and scale in small and medium sized systems.
The impacts of biofilm on heat exchanger efficiency are dramatic. The following excerpt from the Influence of Fouling biofilim on Heat Transfer clearly explain the negative impact biofouling has on heat exchanger efficiency.
“Bacterial biofilms may also foul heat exchange equipment, especially after a process leak or influx of nutrient. The sudden increase in nutrient in a previously nutrient-limited environment will send bacterial populations into an accelerated, logarithmic growth phase. The biofilms that develop will then interfere with heat transfer efficiency. Table 1 demonstrates the thermal conductivity of a variety of deposit-forming compounds compared to biofilm. A lower number indicates a greater resistance to heat transfer (Characklis, W.J. and Marshall, K. C., Biofilms, John Wiley and Sons, 1990, pp. 316.).”
Cooling Tower Clean-up
An 800 ton CT at a detergent plant was allowed to become severely fouled. The approach temperature was 4 times above normal.
165 ppm of BCP® 2175 was applied in a slug dose into the sump. In 11 minutes a field technician took this video.
By the end of the second day of the clean-up procedure approach temperatures returned to normal at 3.5 degrees Farenheit!
Keeping a Chiller Clean
A Midwest plastic injection molding plant used small mobile chillers to produce low temperature chill water to chill the molding process.
Biofilm formation on the heat exchange surfaces in the chiller caused poor cooling and led to numerous production problems.
BCP® 1015 was dosed at 12 ppm once per week along with a few ppm of biocide. Downtime due to condenser fouling was eliminated!
