Schmitz+Krieger GmbH in Cologne produce new replacement components from old vehicle engines and gearboxes. However, recycling is not the only commitment that the company has to saving resources: the environmentally-certified company also operates a modern plant for the recycling of washing water.
Waste water treatment - the saving of expensive fresh water and the avoidance of expensive and harmful waste water
The recycling plant treats the waste water produced by washing the old parts. The process was developed in conjunction with Ecotec Verfahrenstechnik GmbH and Schmitz+Krieger GmbH and includes an ozone generator and various metering pumps supplied by ProMinent. These are essential for the high quality of the water and are responsible for the reliable disinfection of the waste water. In the last six months alone, over 2,000 m3/a of waste water has been treated using this system technology - and the same volume of fresh water has been saved.
"The waste water that is highly contaminated and environmentally harmful from washing the old components would take a sewage treatment plant right to its limit," explains Achim Birr, Managing Partners at Schmitz+Krieger. The company then returns the treated waste water as industrial process water to the washing machines and high-pressure cleaners.
"In 2004 we learned that there were significant potential savings to be made within our company with process water and waste water - not just in terms of environmental pollution, but also in terms of the overall profitability of the processes," Mr. Birr goes on to say. In the same year the company installed the new waste water treatment plant with financial support from the state of Northrhine Westphalia. "The plant is designed in such a way that our operational personnel can manage and maintain it," comments Mr. Birr. "It has now been running for over five years almost without a hitch. Calculating its full cost, the plant will have completely paid for itself within the next twelve months - and all this just by conserving the environment. Sustainability can be worthwhile after all!"
