BCP Product Maintenance Programs

Maintain Clean Industrial Cooling Water Systems with AMSA BCP™ Chemistry!

Industrial cooling water systems that are not kept free of biofouling do not run at maximum efficiency and can experience a variety of issues.

The chart below summarizes operational issues that can be caused by not keeping an industrial cooling water system clean of organic deposits.


When used in a maintenance program, AMSA BCP™ chemistry can make your standard cooling water treatment program better at controlling organic deposits and avoiding the operational issues listed above.

Examples from the Field – Keeping it Clean!

Keeping a Challenging Cooling Water System Clean with BCP™ 1015

An air scrubber system and cooling tower in a plant with high ammonia and alcohol solvent vapors had a long history of rapid, extensive biofilm growth which was difficult to control with biocide alone. An aggressive one-week cleaning program based on twice daily BCP™ 1015 treatments, applied in the air scrubber, removed biofouling deposits from the system.

A less aggressive cleaning program based on daily BCP™ 1015 treatments, applied in the cooling tower over a period of several weeks, successfully removed biofouling deposits from the tower fill and throughout the system.

A maintenance program based on twice daily BCP™ 1015 and stabilized chlorine dioxide treatments was implemented to control biofouling in this difficult system. Read the full case study for more information.

A Tape Manufacturing Plant – Cooling system prone to fouling cleaned up and kept clean with BCP™ 1015

A tape manufacturing plant located in the Midwest was prone to microbiological fouling. The solvent toluene is used in the manufacturing process. Trace levels of the toluene were introduced into the make-up water for the cooling tower at the plant. Toluene is a food source for bacteria which caused the rapid formation of biofilm on the surfaces of this cooling water system. The fouling was so prolific it caused the collapse of the cooling tower fill!

Clean up Program

A clean-up program consisted of dosing with 2 alternating biocides:

1) Oxidizing Bromine based microbiocide

2) Non-oxidizing Biocide: 20% DBNPA

BCP™ 1015 was dosed as a cleaner/dispersant in this program at 200 ppm 3 days per week for 3 weeks (9 doses).

Maintenance Dosing

BCP™ 1015 was dosed at 100 ppm 3 times per week.

A biocide was dosed as needed.


Within 60 days, the cooling water system was visibly cleaner and


AMSA BCP™ Chemistry Maintenance Program – Slug Dose

  • Dose at 25 – 65 ppm of BCP™ 1015 or BCP 2175.
  • Dose 1-3 times per week.

(Note: the frequency and quantity of dosing are depend on the system’s re-fouling rate. That rate may vary with the season. )

  • Best practice is to feed BCP™ chemistry first so organic deposits are released from surfaces and then dose with a biocide to kill bacteria in the bulk water.

Note: With a slug dose program the system is allowed to foul to an acceptable level before the next ‘slug dose’ removes the deposits that formed in the system.

See the BCP 1015 or BCP 2175 application guide for complete dosing guidelines.

AMSA BCP™ Chemistry Maintenance Program – Continuous Feed

  • Dose BCP 6010 at 50-150 ppm of product based on blowdown.
  • Chemistry is best fed into the basin or with make-up water.

Note: BCP 6010 is designed to be used with a continuous oxidizing biocide program, but can be used with slug fed oxidizing and non-oxidizing biocides.

See the BCP 6010 application guide for complete dosing guidelines.
