Commercial Property Owners must consider many factors when choosing the right water treatment system. Post and cross contamination of the municipal water supply, ineffective residual protection, challenging groundwater, iron and sulphide, aging and complex water infrastructure, dirty water pipes, health focus and the growing eco-friendly trend away from chlorine drive these decisions.
The SanEcoTec® Water System introduces Huwa-San® Peroxide Technology, the new generation of hydrogen peroxide which overcomes the water quality issues of a large or complex water distribution network.
Proven Performance - A Case Study
The study reports on the use of an alternative drinking water sanitizer, Huwa-San® DW Peroxide
Technology to control Legionellosis in a large hospital campus containing 24 buildings. The hospital was
faced with the problem of having to eradicate legionella bacteria from a complex water distribution
system without decanting patients or subjecting them to undue stress.
After rigorous risk assessment, the hospital installed a continuous dosing system in March 2006 and the conclusion was that continuous dosing of Huwa-San® DW Peroxide Technology is the best alternative to chlorine dioxide dosing or copper silver ionisation treatment.
The results before and after continuous dosing of Huwa-San® DW require little explanation. Huwa-San® DW dosed at a continuous level of 10ppm to the ring main has eradicated the number of Legionella positive results found in samples taken from the hospital water system.
The results prompted the Hospital to reduce the frequency of microbiological testing from monthly to quarterly. This decision has been ratified as there has not been a Legionella positive result or TVC since continuous dosing began in 2006. Data available on request.
