Maintaining Microbiological Control in Cooling Towers

Go Beyond the Clean-up Power of AMSA BCP™ Chemistry - Witnessing the clean-up of a heavily fouled cooling tower or cooling water system can be a dramatic experience. Many customers are sold on the strengths of AMSA BCP™ products to penetrate/disperse/clean biofilm in cooling water systems after seeing clean-up applications similar to the one pictured here. In fact, many customers have won accounts by performing chemical cleanings in cooling towers, chillers, and closed loop systems with AMSA chemistry.  However, a good cooling tower maintenance program prevents the need for cleaning a ...

Biofouling Control in Small Cooling Towers

Why is biofouling control overlooked in small cooling towers? Biofouling control in small to medium cooling towers is overlooked. AMSA, Inc. has developed a simple technology that is easier to dose than more common liquid chemical equivalents.  DTEA II™ Slow Release tablets give personnel at schools, hospitals, and office buildings a safer treatment option that can last up to 30 days.  Most importantly, when used in conjunction with a solid form of DBNPA, such as, AQUCAR™ SUMP BUDDY™ DB 40 TL Water Treatment Microbiocide you have an effective Biofilm Control Program™. This short video shows ... Read more >

New Patent: Use of BCP™ 5000 for Sulfur Deposit Control in Geothermal Power Plant Cooling Water.

AMSA, Inc. is pleased to announce the issuance of US patent 9,365,444, “Formulations for use in sulfur scale control in industrial water systems.” In particular, it claims a method for removal and inhibition of elemental sulfur deposits in geothermal utility cooling water systems. Foreign patents covering other countries with important geothermal resources have also previously issued or are pending. The sulfur fouling problem Geothermal energy production is an important and growing segment of the worldwide energy picture. In geothermal power plant cooling water systems where hydrogen sul ...

Why is There Foam in My Cooling Tower?

Foam in Cooling Towers Treated with BCP™ 1000 and BCP™ 2000 Series Cleaner/Dispersant Products - Foam happens - Foam generation is a common natural aquatic phenomenon, occurring in lakes, rivers and throughout the world’s oceans. Natural foams formed at a waterfall (left), and at the seashore. Foam formation requires the presence of a surface active agent (surfactant) to reduce surface tension at the air-water interface.  It also requires the input of mechanical energy to mix air into the water.  In natural environments this mechanical mixing energy might result from wave action, wind ac ...

Learning to Live With Biofilm: The Challenge of an Effective Biofilm Control Program

The organism always wins. This is the challenge of biofilm control. Microbial biofouling and its root cause, biofilm, cannot be totally prevented, at least for a practical length of time in industrial settings. We have many approaches to keep it at bay but it will always be with us. Biofilm Mission Control In industrial water treatment, our goal is to keep biofouling under control. We should target treatments that keep the effects of biofilm below a detectable “threshold of interference” (i.e., the point at which an industrial process is impacted negatively). When biofilm growth rea ... Read more >

Does your cooling tower have a biofouling problem?

What's growing in your tower? It’s important to be able to identify microbial biofouling in the industrial cooling systems that you treat. We know that biofouling is a bad thing … reducing the heat transfer performance of a cooling system, as well as causing microbially induced corrosion, harboring pathogens, and accumulating scale deposits. All these problems can lead to increased costs … and headaches for the water treater. But microbial biofouling, and its root cause, biofilm, may be hard to observe within the mostly hidden surfaces of a cooling system. A biofilm layer that is not even perce ... Read more >

The Importance of a Dispersant in a Legionella Control Program

Outbreaks in Legionnaires’ Disease such as the one in the South Bronx of New York in August 2015 highlights the importance of having effective biofilm control as part of your overall industrial water treatment program. Legionella bacteria grow in biofilms in building water systems, where they are protected from the disinfecting action of oxidizing and non-oxidizing biocides. The importance of biofilm control is highlighted in the following excerpt from "Biofilms: The Stronghold of Legionella Pneumophila". “While L. pneumophila replicates within environmental protozoa, colonization and pe ...

Is there an advantage to Private Labeling?

Private labeling is one way to stay ahead of the competition. As the chemical manufacturer of BCP™ 1015 (DTEA II™), AMSA, Inc. has spent considerable time, effort, and money creating a brand awareness to our chemistry.  We are proud to have established such a strong, positive image as a manufacturer of this very powerful chemistry. BCP™ 1015 (DTEA II™) is held in high regard as an organic deposit penetrant, dispersant, and cleaner throughout the industrial cooling water community.  This is a reputation we have worked hard to achieve and will work hard to protect. Over the years we have re ... Read more >


What do you get when you cross a group of scientists fascinated by the function of molecules and biofilm with a group of industrious sales/support professionals dedicated to providing the highest level of service to their customers?  AMSA, Inc.! AMSA, Inc. was founded in 1996, when Dr. Attila G. Relenyi, left his career with Dow Chemical to pursue his vision of bringing the knowledge of biofilms and how to best control them along with the innovative technology of DTEA II™ chemistry to the industrial water treatment market.  With many charts, plots, and explanations of how AMSA’s class of che ...
