“…The performance of the pilot-scale UV / H 2 O 2 system in the treatment of sulfolane contaminated groundwater in a reservoir with a volume of 5.6 m 3 with an optimal concentration of hydrogen peroxide was 40 mg /l [9]. A pilot-scale study on the application of hydrogen peroxide for disinfecting Johns Hopkins Hospital curtains in the United States indicates that a concentration of 3.1% of hydrogen peroxide can remove C. di cile, MRSA, and VRE bacteria with 100% e ciency [10]. A fog solution containing 5% H 2 O 2 with 0.005% silver has been used as a disinfecting agent in the food industry to remove a mixture of four L. monocytogenes strains in a 36 m 3 chamber [11].…”

Since the operating conditions of the cooling tower units provide such a suitable environment for the growth of bacteria and algae, taking measures for the disinfection process is strongly recommended. The cooling tower unit is proceeded by RO and the disinfection strategy is sodium hypochlorite, combined with this new formulation. The sampling result revealed that bacteria counts from the effluent of the cooling tower are 2600 CFU/ml while the microbial load of the water in the pond is 220 CFU/ml. Herein, two type formulations are introduced for cooling tower output stream while the pond water comes along with a NaOCl injection. The dosage of A: Glucose Oxidase, B: ammonium persulfate, and C: Amoxicillin, and D: the order of use are chosen as the four independent variables whose effects and their binary interactions on microbial load and disinfection efficiency were investigated via Box–Behnken design (BBD) combined with response surface methodology (RSM). The ANOVA results show that the most significant variable is amoxicillin in the presence of bleach. Meanwhile, high values for R2 > 0.99 and the model F-value 45.64 in addition to diagnostic tests confirmed the reliability of the model. Several solutions have been introduced as optimum formulations. The pre-scale up and economic considerations have been included.

“…Some have taken finger imprints from curtains actively hanging in hospital rooms (3,14,16,17,21,22,24). Others have inoculated known concentrations of bacteria onto specified areas of curtain swatches (13,27) or hospital fabric (20). These studies have also differed in duration from as short as seven days (17) to as long as six months (3,14,25).…”

The Persistence of Staphylococcus aureus on Hospital Privacy Curtains

While healthcare professionals are working in hospitals, they will often manipulate the privacy curtains during the care of their patients. Studies have shown that the transfer of bacteria from hands to the curtains and vice versa is possible. Despite the possibility of hospital curtains being a mode of infection transmission, studies have shown that 53% of hospitals surveyed did not have a policy for cleaning or changing their curtains. The question that this study focused on was whether curtain material affects the persistence of Staphylococcus aureus. In this study, five different curtain types were inoculated with overnight, diluted, and finger imprint cultures of S. aureus. They were incubated at room temperature and were sampled for growth regularly onto Mannitol Salt Agar plates. The colonies were counted, and one-way ANOVA statistical analysis was completed on the data. The statistical analysis showed that the length of persistence of liquid cultures of S. aureus on the curtains was not dependent upon initial concentration. Finger imprint inoculations of four curtain varieties had statistically significant longer persistence times than the liquid cultures. Only the curtain type composed of 100% antimicrobial polyester with water repellant had significantly lower persistence times for the finger imprint culture than the other four curtains. The results suggest that the 100% inherently flame resistant antimicrobial polyester curtain material reduces S. aureus persistence times and that it may benefit hospitals to use this type of curtain.
