SmartTrim

October 16, 2011

One of the most successful in the framework of cooperation is the project of improving wastewater treatment technology at the Central wwtp (their capacity is 1500 thousand m3 / d, making this facility one of the largest in Europe). It was realized thanks to the support The John Nurminen (Finland) and the program "Clean Sea". It must be noted that, apart from the obvious benefit to the environmental situation in the north of Europe, the city has received and the obvious savings: up reconstruction treatment plant was propeller is equipped with 12 pumps of 125 kW each. They replaced the same number of pumps grundfos S series with a twofold lower power consumption. In addition, significantly reduced maintenance costs, largely through the use of patented node SmartTrim, which allows you to adjust the clearance of the impeller without disassembling the pump. Downtime, thus, was drastically reduced.

Equally indicative of the situation on the smaller networks – in the city of Kursk. Due to the topographic features – hills – the local sewerage system is one of the most complex in the Central Federal District of Russia and includes more than 30 cnd. cnd 32 'Burnt Wood', was built more than a quarter century ago, is part of the mup "Kurskvodokanal and pumps the sewage from a large area – Railroad District (with a population of about 80 thousand inhabitants) – the main pumping station (STS). kns serves not only the municipal sector, but also large industry, and handles sewage volume of about 1800 m3/hr. Initially, the anc had established Soviet-made pumps, each with a flow rate of 2,700 m3 / h flow pressure at 25 meters.

Capacity of each high-voltage unit was 400 kW. Over the years, this equipment is obsolete and no longer meet the needs of the city. Therefore, the cbm has decided on a phased replacement of pumps, and the selection criterion is the reliability and energy efficiency. As a result, after a joint inspection and measurement parameters of the cnd, were mounted in 2 modern low-voltage sewage pump grundfos S-Series to 160 kW (one pump in operation, one in reserve), the pressure of 23 meter and flow 1800 m3/hr (project developed by the Institute ''). In addition, the knu has been fully automated. Optimization of modes of cnd, the proposed engineers grundfos, allowed more than 4 times to reduce the consumption electricity and substantially reduce maintenance costs cnd. An additional argument in favor of the choice of modern pumps has a choice of vertical or horizontal arrangement of units. As a result, were applied vertical pumps, so it does not have to spend a large amount of construction works and change the construction of the station – equipment perfectly fit into the existing cnd. Also worth note that the high professionalism of all the water utility services, enabled the replacement of equipment without stopping the anc. Today, the use of advanced energy saving technologies can not only improve the quality return on utility performance and make them cost effective. Modernization provides an opportunity to accelerate development and their clients – municipal agencies and commercial organizations – all those who are interested in receiving quality public services at reasonable prices. So, ultimately, the entire population. Press office of the company "Grundfos"
