3 Potential Causes of Microbiological Fouling

Posted by David Burroughs on May 31, 2016 10:24:05 AM

 

In our next post in this series, we want to discuss causes of microbiological fouling. This type of fouling occurs when planktonic, or free floating bacteria, attach to surfaces throughout the cooling system. As they attach, the bacteria will form a slime barrier that is used to protect the bacteria and to enhance the ability to stay attached to the surface. This environment they produce also helps with growth of the bacteria as it is a stable surrounding that can provide the food and protection needed for the bacteria to flourish.

Use Cooling Tower Scale Inhibitors & Water Chemistry to Limit Fouling

Posted by David Burroughs on Apr 7, 2016 2:16:58 PM

Scaling is one of the most common types of foulants to occur on heat exchanger surfaces. When we refer to scale, we most often mean mineral scale that develops most commonly as calcium or hardness based salts such as calcium carbonate. These salts are unique in that they exhibit reverse solubility e.g. they become less soluble in water as the temperature rises. While the relationship between temperature and the level of salts in the water will determine if scale will form on the heat exchanger, there are relatively easy ways to control this type of scale in most situations.

4 Common Types of Cooling Tower Fouling

Posted by David Burroughs on Feb 24, 2016 5:22:56 PM

Cooling tower system operation requires that a close eye be kept on performance in order to maintain cost and efficiency across the life cycle of the equipment. Heat exchanger fouling is a serious problem and can have a major impact on the performance of the systems if left unchecked.

Curse of the Aluminum Heat Exchanger

Posted by David Burroughs on Sep 2, 2015 10:00:00 AM

Aluminum has always been used in various cooling systems, such as injection molding. Over the past several years however, the water treatment industry has seen even more use of the metal in heat exchangers and hot water boilers. The reason for this industry shift is the light weight, easy fabrication properties and excellent heat transfer characteristics of aluminum. The problem this presents is that aluminum doesn’t play very well with the traditional treatment chemistry used in closed systems. This week’s blog will review some of the basics with aluminum metallurgy and discuss some of the keys for treatment.

Legionella Update – How Would You Handle an Outbreak?

Posted by David Burroughs on Aug 19, 2015 2:20:00 PM


Back in June, QualiChem had a blog post on the approval of AHSRAE 188 which covered Legionella Risk Management Standards for the industry. With the recent legionella outbreaks in New York City and the fact that there generally are an increase in positive Legionella tests during the summer, we wanted to use this blog article to briefly discuss potential measures to take in response to a positive test in your cooling systems as well as share what the City of New York is doing in response to these outbreaks.
