Hans Schmidt GmbH
When large volumes of industrial wastewater containing cooling lubricants and emulsions need to be treated, a solution is required that both ensures effective treatment and reduces the need for disposal. For Hans Schmidt GmbH , this challenge became an opportunity to optimize the treatment of their industrial wastewater through a modern and effective solution from ENVOTHERM.
About Hans Schmidt
Hans Schmidt Altöl- und Abfallverwertung GmbH, located in Fürth, Germany, is a medium-sized, family-owned collection facility with 200 employees. The company specializes in the collection and treatment of environmentally hazardous industrial wastewater from throughout Germany using 75 tanker trucks.
Hans Schmidt's Challenge
Hans Schmidt receives 12,500 m³ of used cooling lubricants,emulsions, and other industrial wastewater annually, which until now has been disposed of through external service providers. This process resulted in annual costs of EUR 625,000 until 2008.
The Solution
ENVOTHERM leverede et ET2500 spildevandsanlæg, som opkoncentrerer emulsionerne og adskiller vandet fra koncentratet. Resultatet er, at 90-93 % af destilleret vand kan ledes til offentlig recipient, mens de resterende 7-10 % koncentrat indeholder 40-60 % olie og kan genbruges af cementfabrikker. Destillatet har et olieindhold på <10 ppm, hvilket er under halvdelen af de gældende udledningskrav.
ENVOTHERM's patented absorber reduces the COD value of the distillate, which means that no additional discharge fees are imposed by the authorities.
This solution enabled Hans Schmidt GmbH to recycle significant amounts of waste and significantly reduce its emissions, while achieving a return on investment in just 6 months.
