FEASIBILITY STUDY OF USING COMPLEX OF HYDROGEN PEROXIDE AND SILVER FOR DISINFECTING SWIMMING POOL WATER AND ITS ENVIRONMENT

In this research the application of nanosil containing hydrogen peroxide and silver was studied indisinfecting swimming pool water and it’s environment. the effect of the disinfectant on candidaalbicans (atcc no. 10231), aspergillus niger (atcc no. 16404), pseudomonas aeruginosa (atccno. 9027), serratia marcescens (ptcc no. 1111), klebsiella pneumoniae (atcc no. 10031) andstaphylococcus aureus (atcc no. 29737) ) was evaluated. the main objective of this experiment was todetermine the effective dose of nanosil which could be used for disinfecting the environment ofswimming pools and other surface area. then, the effectiveness of nanosil was studied in two private andone public swimming pools. heterotrophic plate count, thermotolerant coliforms, pseudomonasaeruginosa and staphylococcus aureus were monitored as the target microorganisms in disinfectionpractice according to the result of this study, it is recommended to apply the nanosil with theconcentration of >3% (30000 mg/l) for contact time of 30 min or more for practical disinfection inswimming pools environment. the application of nanosil in real conditions of two private and one publicswimming pools indicated that the acceptable microbial quality is also achievable if the disinfectantresidual concentration would be as high as 20 mg/l in swimming pool water.
