The equipment will provide reliability and accident-free operation of purification plants.

In design, we set new design solutions that will contribute to fulfilment of sewage water treatment best practices, accepted in the country, in the next 20 years. Equipment was manufactured from high quality corrosion-resisting materials. The sludge sweeping unit operation procedure is fully automated and can be included in the general dispatching system, that will allow spending less time on maintenance and thereby reducing operating costs.
