EFFECT OF GUSTOR LIQUID IN WATER QUALITY

OBJECTIVE The objective of the study was to evaluate how Gustor Liquid improves the microbial quality of water with different hardnesses infected with E Coli.

MATERIAL AND METHODS Products: GUSTOR Liquid Dosage: 2 kg/1.000 liters Strain: Escherichia Coli ATCC 35218 Initial contamination: 10 5 UFC/g Water Hardness: Soft water (37.5 mg CaCo3/l) Medium water (112.5 mg CaCO3/l) Hard water (225 mg CaCO3/l) Very Hard (337.5 mg CaCO3/l)

RESULTS GUSTOR LIQUID removed 100% E Coli contamination In soft water after 1 hour of application In medium water after 2 hours of application reduced by more than 99% the E Coli contamination In hard water after 90 minutes In very hard water after 4 hours reduced by more than 80% the E. Coli contamination In soft, medium and hard water after 30 min

CONCLUSIONS The bactericide effect of GUSTOR LIQUID is depending of hardness of water and contact time. GUSTOR LIQUID has bactericide effect vs E Coli in less time for soft water than medium water. reduced E Coli contamination in less time for hard water than very hard water.
