Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous germicidal agent including peracetic acid and performic acid capable of easily adjusting its effect and rapidly acting and high in bacteria-eradicating rate. SOLUTION: In the production, 0.1 to 1.0 mole of formic acid or 0.1 to 1.0 mole equivalent of the aqueous salts of formic acid per 1 kg of the germicidal agent is added as the formic acid source, to an aqueous phase including 20 to 60 wt.% of hydrogen peroxide, and balanced peracetic acid solution including 0.5 to 6 wt.% of peracetic acid, less than 10 wt.% of acetic acid and up to 3 wt.% of mineral acid, and this mixture is permitted to stand for at least 5 minutes to 5 hours before use.

Abstract: The invention relates to a method of reducing harmful organisms in currents of water. The aim of the invention is to improve the already known methods of treatment for reducing harmful organisms such as algae, mussels and slime- producing organisms by adding a solution that contains peroxy carboxylic aci d. To this end, the currents of water, especially cooling water currents are treated in an economical manner by adding to the flowing water the treatment agent once every 5 to 100 hours over a period of 3 to 60 minutes in an amoun t that corresponds to at least 1 ppm peroxy carboxylic acid.

Date Mar. 6, 1997Owing to the concomitant storage, transport, material and handling problems and the unsatisfactory retarding of reinfection, the use of commercially available peracetic acid solutions with a high peracetic acid (PES) and acetic acid content for disinfecting large quantities of aqueous solutions, e.g. purification plant outlets, has been closely limited. It is possible to disinfect even large quantities of aqueous solutions economically and at the same time retard reinfection by using a peracetic acid solution containing 1.5 to 2.5 wt. % peracetic acid and 40 to 60 wt. % hydrogen peroxide and under 2 wt. % acetic acid as a disinfectant. The use of a peracetic acid solution with less than 1 wt. % acetic acid is preferred.
