Our productions are certified by the European quality standard ISO 9001. In 2006, the whole model line was renewed on the basis of the latest SHD-system. This system allowed us to convert to a purely temporal principle of work phase formation and to refuse from the use of any working level sensors. Levels in plants are maintained by specially developed process elements, which allow to treat domestic sewage of different composition, using different algorithms. Our short-term plans include the development of the safe and affordable system of circulating water supply a basis for environmental safety. After all, soon the time will come, when the availability of pure water will be the priority state program and those, who own pure water, will have great wealth.
