H2O. Leaders in Zero Liquid Discharge.


The premiere of our first webinar is behind us. So many interested parties ensured a lively exchange - we are pleased that the first webinar was so well received. So well, in fact, that a repeat was requested - we are of course happy to comply with this request. We have also prepared a further free webinar for you.

Good - better - Purecat! Reduce your COD values by a total of 99 percent! And all that without activated carbon! Sounds promising, doesn't it? It is: our new Purecat technology makes it possible.

We have good news! The VACUDEST ZLD technology is now available and ensures wastewater-free production for you, too!

For more than 14 years, we have been able to set high standards in the efficient treatment of heavily polluted industrial wastewater thanks to our patented Clearcat technology. With the production of the ZLD 300 we exceed this result and take a new important step towards wastewater-free production!

"The Harting Technology Group is a leading international supplier of industrial connection technology for the three lifelines data, signal and power with 13 production facilities and 44 sales companies worldwide" ( As a family-owned company with a long tradition spanning more than seven decades, ecological responsibility is a fundamental component of the Harting Technology Group's actions. Thus, the course towards wastewater-free production with the VACUDEST process was set early on at the main plant in Espelkamp. This fundamental decision in favour of ecologically sensible action in combination with economic considerations was also already supported during the company's development in China.

We take the current situation concerning the outbreak of Covid-19 very seriously. We keep ourselves regularly informed and try to act pre-emptively and react to the new situation in the best possible way.

With our news ticker we inform you about the developments at H2O GmbH on a daily basis.
