Elimination of micro-organisms and pathogens
The microbial growth in cooling water systems is determined by the amount and type of microorganisms, as well as origin and preparation of water. This can lead to significant changes in the microbiological situation in certain circumstances. In addition to fungi, protozoa and algae, numerous types of bacteria of different genera also those of epidemic hygienic relevance, can be found.
Microbiological contamination of Legionella in cooling water systems have fallen increasingly in focus of the public, in recent years. The hygienic requirements for evaporative cooling systems are currently defined in accordance to the VDI guideline 2047.
In biofilms of cooling water systems, typical water bacteria with pathogenic potential (opportunistic pathogens) may settle, such as Legionella, atypical mycobacteria or Pseudomonas aeruginosa, which are not always killed by conventional cleaning and disinfection processes, since the microorganisms are in a slimy matrix of extracellular polymer substances (EPS) embedded and thus are protected against biocides.
Biofilm and biofouling are a serious danger for open and closed cooling water systems. Biofilms in cooling systems reduce the cooling capacity due to the reduced heat transfer and increase the risk of microbiologically influenced corrosion (MIC). This form of corrosion can very quickly lead to critical damage and decrease the availability of the systems drastically.
The WEICOGARD®-T product line is especially developed for effective treatment of microorganisms such as bacteria, fungi and algae in industrial water systems.
The WEICOGARD®-T Product group includes oxidizing and non-oxidizing biocide agents.
From today's perspective, one should combat biofilms by using combined processes.
Under combined process is understood, the use of one or more biocidal active substances in combination with a so-called Biodispergator or organic dispersant.
A new development of a combined biocidal product (WEICOGARD® T 910), based on a highly efficient activated bromine compound in combination with a Biodispergator can lead to an effective hygienic protection (removing and killing effect) in cooling water systems. The effectiveness compared to conventional oxidizing biocides, with a combination of biocide and Biodispergator, is 30-40% higher.
The spectrum of action is extended to aerobic (Legionella) and anaerobic bacteria, algae and fungi.
Through the dispersing effect of WEICOGARD® T 910, the biocide penetrates even in strongly existing microbiological deposits, kills and removes them.
