In operation throughout the world
In 1997 Wilo provided a Wilo-EMU Uniprop TR 60-2 mixer free of charge for evaluation purposes in a sewage treatment plant. After operating for a whole year, the mixer was removed, dismantled and presented to the plant operators and representatives of the municipal authorities.
Although the mixer had not been serviced during the entire period, it revealed no signs of wear at all. Everyone was suitably impressed. The system from Wilo had provided better performance – with significantly lower power consumption. In consequence, Wilo installed two mixers during the initial expansion phase in 1998/1999.
As a result of the faultless performance of these two systems, the company was also awarded the contract for phase two of the expansion in 1999/2000, which was at the time the most significant use of Wilo mixers in the USA. The old R.M. Clayton sewage treatment plant was eventually entirely replaced with 134 Wilo-EMU Uniprop TR 22.174 and TR 60-2 mixers.
These were installed in lines with mixed media in treatment stages one and two and, for the first time, for nutrients disposal.
Water supply
Fresh and pure water is a dwindling resource. That’s why the extraction and appropriate planning for the provision of this valuable resource present a permanent challenge. Moreover, various new methods of obtaining potable water have been developed – and the number of sources from which potable water is extracted has significantly increased, for example, the use of desalinated seawater or aquifers (geological ground water reservoirs). Against the background of such a wide range of sources, water purification systems must become more flexible to keep up with developments and the widely varying qualities of the waters extracted. This requires pumps and components that are capable of a combination of optimum media extraction,
efficiency and long-term reliability in each respective system.
Sewage disposal
Increasing threats to our environment demand improved and more efficient waste management. The multitude of chemical and biological pollutants contained in household, commercial and industrial sewage presents enormous challenges to the appropriate and safe treatment of these dangerous substances. Disposal over extreme distances – by means of pressurised drainage or largescale pumping stations – ensures safe transportation of sewage from its origins to treatment plants where carried solids and contaminants are removed and biological treatment takes place. The right choice of pumps and systems guarantees continuous and dependable sewage disposal with the highest achievable safety standards and lowest possible costs.
Sewage treatment
In sewage treatment plants, the harmful components of household, commercial and industrial sewage are removed. A long and cost-intensive process is necessary in order to treat sewage in such a way that the resulting water can be fed back to the water supply cycle without any concerns. The authorities responsible for the process constantly face financial pressures, local regulations and laws. Sewage treatment plays an increasingly important role in the conservation of water resources. Continuous challenges, such as increasing solids content in sewage – which negatively influences the operational conditions for plants and installations – demand new and innovative solutions to enable the improvement of processes and of process-relevant products.
