At SITRA we have effective tools to determine the most effective treatment at a lower cost.
Specifically, we have developed Bioefficacy Studies that allow us to isolate the specific microorganisms colonizing a facility, reproduce them in the laboratory, and then expose these specific strains to a range of biocides to determine their effectiveness. This system allows us to optimize the treatment used in each case, both effectively and economically.
Biocides are used to control the presence of microorganisms in water in industrial processes, including cooling circuits, water treatment, and industrial processing water circuits, among others.
To ensure their effectiveness in each facility, biocide application programs must be based on specific crop and sensitivity tests against effective agents for each of the specific species that need to be controlled. Furthermore, when studying each specific system, the potential side effects that the addition of a particular product may have on the production process must be taken into account.
Microorganisms in general are capable of developing resistant forms in a given environment, so it is necessary to periodically review the control program used. And, to make the program cost-effective, treatments often combine a highly effective but expensive biocide with a broader-spectrum, more economical one, thus making the total cost of the treatment reasonable.
However, in the Bioefficacy Studies that we have developed, the laboratory plates are seeded with isolated aerobes and exposed to various biocides, which allows the formation of an inhibition halo proportional to the inhibitory effect that each biocide studied has on the microbial load used.
Among other advantages, this system allows us to comparatively quantify the effectiveness of the various biocides studied and determine the cost of treatment based on the optimal doses found.
The use of this analysis and control tool on a regular basis also allows us to maintain the microbiological quality of industrial waters and control them at the best cost without the treatments losing their effectiveness due to the possible appearance of resistance to the previous treatments used.
