BCP™ 6000 Series Products: Continuous Feed Maintenance Cleaning Chemistry for Industrial Cooling Water Systems
AMSA BCP 6010 is a unique ‘Ready to Use’ industrial water chemical specifically designed to work with a biocide program to maintain clean cooling water systems.
Biocide + BCP 6010 = Consistent, ongoing control of biofouling processes & continuously cleaned surfaces
BCP 6010
A maintenance cleaning chemistry that penetrates, disperses and cleans organic deposits in process cooling water and commercial and residential building comfort cooling systems.
It is designed to be fed in a continuous dosing program. This approach brings numerous benefits such as:
- Easy to dose – Requires standard dosing pumps and can be coordinated with your inhibitor chemical dosing system
- Less variability in dosing – The question of ‘how frequent to dose in order to maintain a clean system’ is taken out of the equation.
- Easy to optimize – Dial up or dial down the continuous rate depending on system refouling rate.
- High degree of yellow metal corrosion inhibition – The inherent yellow metal corrosion inhibition properties of BCP 6010 are fully operational as the chemistry is circulating in a system that has ‘continuously cleaned’ surfaces.
- Legionella and other pathogens are less likely to be detected – Systems kept at a high level of cleanliness are less likely to produce a ”Legionella hit’ during a routine monitoring programs.
- Cost savings from efficient chemical use – Biocides and inhibitor chemicals can be used effectively at their lower label limits when dosed in a clean system.
- Peak system performance – Continuously cleaned systems allow for maximum heat exchange and cooling efficiency.
Costs of an Ineffective Biofouling Control Program (BCP)
Cleaning a cooling system only at the start of the cooling season and prior to winter lay-up runs the risk of operating the system with high levels of biofouling during peak demand months.
This approach is costly in terms of:
- Running the system in the problem zone for much of the cooling season (as illustrated in the chart below)
- Limiting cooling performance
- Promoting corrosion and scale
- Encouraging colonization by Legionella and other pathogens.
Controlling Biofouling with biocide only – Cleaning the system 2 times per year
This chart illustrates a potential scenario for biofouling in a cooling water system that is dosed with cleaning chemistry only twice annually.
Slug Dose BCP Maintenance Program – A cleaning program with BCP 1015 or BCP 2175
A Biofouling Control Maintenance Program based on biocide plus frequent low to moderate concentration slug doses with AMSA’s BCP industrial cooling water chemical, cleaner/dispersant will keep a cooling water system clean to a ‘target level of cleanliness’ if optimized correctly.
Slug Dose Maintenance Programs.
Treatment programs based on slug dosing require the water treater to specify slug concentration and slug frequency. The quantity of chemical applied in each slug is a calculated based on system volume. The water treater must respond to changes in biofouling rates through the year by adjusting slug dose concentration and/or frequency. A BCP Maintenance program based on slug dosing, as illustrated in the graph below, would typically apply cleaner/dispersant (e.g., BCP 1015) once to three times per week at 25 to 65 ppm.
For more information on the benefits and how to use BCP 1015 or BCP 2175 in a slug dose maintenance program check out the following:
Benefits of a Slug Dose Biofouling Control Maintenance Program:
- Accumulation of biofouling deposits is effectively controlled.
- Cooling efficiency is maintained
- Biocides and inhibitor and scale chemicals are more effective due to clean system surfaces hence less of both are needed to maintain an efficient cooling water system.
- Chemical costs are minimized- depending on the frequency required of dosing
- Pathogen presence is minimized
- System appearance suggests safe, efficient operation
- Life of system is extended
This chart illustrates a potential scenario for biofouling in a cooling water system that uses a slug dose cleaning maintenance program dosed 3 times per week.

Continuous Dose BCP Maintenance Program – A cleaning program with BCP 6010
Continuous Dosing Treatment Programs.
BCP 6010 is designed to be fed via a controller in a continuous feed manner. A continuous treatment program using BCP 6010 would typically be set to apply the product at 50 to 150 ppm based on the blowdown rate. It some cases it may be possible to set dose rate proportional to inhibitor treatments controlled by a tracer.
Having a low level of BCP 6010 in the system continually allows surfaces to be kept clean which eliminates the ‘biofilm growth/clean/regrowth/clean’ cycle of a slug dose cleaning program. The system is constantly running in the optimal control zone.
BCP 6010 is specifically designed to be used with a continuous oxidizing biocide program, such as bleach, but can be used with all oxidizing and non-oxidizing biocide programs.
Benefits of a continuous Biofouling Control Program based on BCP 6010:
- Easy to set up – the chemistry requires standard dosing pumps and can be coordinated with your inhibitor chemical dosing system.
- Less variability in dosing- the question of ‘how frequent to dose to maintain a clean system’ is taken out of the calculation.
- The system is easy to optimize, the concentration of the dose may be varied depending on system fouling rates.
- With system surfaces being constantly cleaned, biocides and inhibitor chemicals can be used at their lower label limits, bringing cost savings while keeping the system running at peak performance.
- The inherent yellow metal corrosion of BCP 6010 will enhance the systems’ corrosion inhibition as the chemistry is circulating in a ‘clean system’.
- Legionella and other pathogens are less likely to be detected in clean systems running in the ‘optimum performance zone’.
This chart illustrates a potential scenario for biofouling in a cooling water system that uses a continuous dose cleaning maintenance program in which system surfaces are continuously cleaned.
