A platinum mining company in South Africa was using chemicals to treat hard water but found significant scale formation in the heat exchanger of one of its cooling towers after just one year of operation. They engaged UET to install their alternative treatment system in a similar cooling tower, in order to compare the efficiency of UET’s non-chemical treatment technology with chemically-treated water. After one year of operation, inspection of the two heat exchangers showed that UET’s technology kept the heat exchangers in one cooling tower clean and free of scale, and dramatically cleaner than the heat exchangers in the cooling tower treated by chemicals.
As a result of this experiment, the company installed UET systems in further cooling towers. They were able to reduce their consumption of expensive treated water, cut their maintenance and cleaning costs and associated down-time, and eliminate their use of hazardous chemicals and their associated costly logistics.
… in the Presidential Green Chemistry Challenge Award in 2009, your product clearly demonstrates both technical excellence and a commitment to protecting human health and the environment. We applaud your contributions to green chemistry.
In every building project we have undertaken with UET we have received excellent advice and seen significant improvements in the water systems within a short time – sometimes within the first month. We have no doubts that UET’s technology yields excellent results very quickly.
The routine service provided by UET includes site visits, water analysis reports, on-going service to the units, replacing consumable items and fixing any problems. The UET personnel are always professional and pleasant. We highly appreciate and strongly recommend using UET’s technology and equipment.
The UET system performs work well, allowing financial savings and contributing to the environment. We plan to test and gradually introduce your systems in our other divisions. We thank UET for your technical support, expertise and dedication to improving our water systems.
In the 35 years that I have worked in water treatment and irrigation, I have never come across such an efficient system. I recommend the excellent service, the rapid response and the professionalism of UET.
UET was chosen to supply systems to treat and recycle waste water utilising their unique technology and know-how. Laboratory results show that the water recycling results exceed the standard requirements, and we appreciate the highly professional way that UET has initiated, designed and installed its integrated solution.
