"LIPETSK AERATION STATION MUE (LISA MUE) notes that, during the cooperation with our enterprise, the Research and Production Company EKOTON, has acquired a reputation as the organization of highly professional specialists, which knows subtleties of the operation of wastewater treatment facilities and develops technologies of the highest world level.We, as an operating organization, are glad of the ratio of the price-quality parameters in respect with products, manufactured at this enterprise. In July 2011, 3 IRPO sludge scrapers with the diameter of 40 m were delivered, installed and put into operation. In June 2012, the sludge sucker with the diameter of 24 m for the sludge compactor was put into operation, while, in the summer of 2013, two 40- meter sludge suckers were put into operation. All installed equipment has been operating stably and smoothly from 2011. One of the main advantages of this type of equipment was the serviceability and reliability. Sludge suckers and sludge scrapers are structurally designed for a long-term trouble-free operation. No wear of moving parts is observed. In particular, the extremely simple, but effective system of the sludge intake system, consisting of one sludge sucking pipe in the contrast of a four-arm sludge intake, proved to be very effective. According to the reports of employees of our enterprise, this design proved to be stable, rigid and reliable in operation. The suction units are designed so that no sludge is deposited on the bottom of the clarifier, because they are equipped with original elastic rubber sheets following the relief of the bottom. Besides, the single-arm design allowed collecting the sludge with lower moisture content. The cleaners of walls and edges of both sludge suckers and sludge scrapers are well designed, convenient in adjustment and don’t cause dissatisfaction. The driving trolleys run smoothly and stably, while the electric part of the drive runs smoothly in various temperature conditions. LIPETSK AERATION STATION MUE thanks the team of RPC EKOTON CJSC for the high quality equipment and careful attention to the needs and requirements of our enterprise during the production, delivery and adjustment of sludge suckers and sludge scrapers."
