Traditional chemical treatment systems have a hard time keeping the water clean, the tower and heat exchanger surfaces free of corrosion, deposits and foam. In addition to destroying beneficial microorganisms, the chemical residues and byproducts in the blow-down are usually toxic and very harmful to the environment.
The new developed Non-Active Biocatalysts as OrTec, substitute all of the chemicals traditionally employed to treat cooling tower water, namely biocides, pH adjusters, algaecides, corrosion inhibitors and anti-scaling products.
By applying them to the makeup water, the existing microorganisms are stimulated and conditioned rather than destroyed, so they work in favor of the natural remediation process rather than against it.
The discharge of the blow down will promote cleansing rather than polluting drainages and treatment systems down the line, since the non-active biocatalysts doesn’t introduce any toxicity into the system.
The non-active biocatalysts will loosen and remove deposits from the cooling system surfaces, and will foster optimum conditions for the biological stabilization of the water, preventing corrosion and the formation of deposits (scale, slime, foam and algae).
More importantly, there are cost benefits too, since it is nearly always cheaper to use a non-active biocatalyst than any alternative combination of chemical products. The expanded life of the tower and heat exchanger, as well as reduced maintenance and repair expenditures, are other important cost advantages. In many cases, it is also possible to reduce blow-down, which can bring additional savings.
Since the Non-Active Biocatalysts are non-hazardous, non-regulated substances that don’t contain micro-organisms or toxic chemicals, they are completely safe and very easy to handle; thus, the tower water (and the blow-down) will remain free of toxic residues and by-products, which is a definite environmental plus, and clearly impacts staff safety and insurance costs.
With the use of non-active biocatalysts the cooling towers need less maintenance, less water use and have a longer life. The use of a safe and cheap non-active biocatalyst makes the blow-down to not pollute. In short a green and economical solution
