Biological Control
Microbial growth in a water system presents two problems: it reduces water quality and, if left unattended, can “grow” to reduce system performance and life. Biofouling can cause a decrease in water flow rate, a decrease in driving pressure, and can contribute to corrosion of piping and equipment.
Growth of algae, fungi, molds, slime-forming organisms and bacteria that infect open recirculating and once-through systems can reduce system efficiency by as much as 50%. These “unwelcome guests” can be controlled with the proper Mid South product.
Let our experts assist you in effectively controlling microbial to keep your equipment at maximum operating efficiency.
OXIDIZING BIOCIDE TREATMENTS
Oxidizing biocides kill bacteria through the electrochemical process of oxidation. Chlorine is the most widely used oxidizing biocide and is applied in most cooling and process waters that operate below pH 8. Bromine-based biocides are more effective at higher pH levels, making them ideal for use in systems that operate above pH 8, up to pH 9.
NON-OXIDIZING BIOCIDE TREATMENTS
There is a wide variety of products related to non-oxidizing biocides. These products operate via different mechanisms than those of oxidizing biocides and require specific review during product selection. System pH, temperature, discharge limits, toxicity, metallurgy and contaminants like ammonia or sulfide should be considered when selecting the appropriate nonoxidizing biocides.
COMBINING OXIDIZING AND NONOXIDIZING BIOCIDES
The combination of oxidizing biocides with non-oxidizing biocides provides exceptional microbial control to address biofouling in systems that are prone to growth. An all-inclusive approach to microbial control can result in improved biofilm control and an increase in heat exchange efficiency.
