Controlling and preventing the growth of microorganisms in a cooling tower is extremely important and required to keep the system running at optimal levels. The presence of microorganisms will cause the system to breakdown and decreases the efficiency of the heat transfer. Typically oxidizing biocides such as chlorine and bromine have been used to treat cooling water. Unfortunately these chemicals are highly reactive with other chemicals and microbiological species found in the water. Chlorine dioxide however is very non-reactive to other compounds found in the water and retains biocidal efficacy. Likewise it is also a superior chemical for removing the biofilm, which leads to the most predominant problems that all cooling towers face.

Monitoring Biomass in (Cooling Tower) Waters through ATP monitoring
The TOXcontrol can be used for ATP monitoring. Currently our company is doing research for further developments for this application on the TOXcontrol.
Monitoring the microbial population of cooling towers is necessary in order to maintain the proper operation of the system. Conventional methods for monitoring microbial populations work by culturing microorganisms, a time-consuming procedure that requires days or even weeks of incubation before the results are known. Biofouling can be well-advanced before treatment begins. In addition, it is believed that this technique does not detect the full range of microbial life present in cooling systems.

teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as pre-separators. Bag filter failure is consequently a very common problem for clients in this industry.
Client`s needs include a very robust dedusting system, either serving as end-stage collector avoiding the need to cool down flue gases, or strongly minimizing the loads of aggressive material to bag filters.
