Our guidebook on the subject of "wastewater-free production".

"An investment in knowledge pays the best interest." - Benjamin Franklin already knew that 200 years ago. That is why we would like to share our expert knowledge with you: Here in our guidebook! On this page you will find informative explanations and interesting facts about wastewater, such as functional descriptions and comparisons of different technologies and processes. Practical and comprehensible. We hope you enjoy browsing and informing yourself!

Processes accumulating waste water

Industrial waste water is the polluted water generated by industrial processes. Depending on its source, it is contaminated with a wide variety of pollutants and must be treated before being discharged into public supply networks.

Hardening shops can minimise their disposal costs through double recycling.

When replacing quenching baths in the hardening shop, there are two cost-intensive challenges: Wastewater containing salt must be disposed of at high cost, and the salt that is lost due to salt carry-over must be added at high cost. The innovation team of H2O GmbH has therefore developed a new technology for vacuum distillation that enables a double circulation for both water and salt. This considerably reduces disposal and operating costs.

How does industrial waste get into water systems and what are its effects?

How much of the world's water pollution is caused by industry? A very considerable amount. Industry accounts for about 20 per cent of the fresh water withdrawn worldwide. This water is used in production and becomes polluted.

Traditionally, electroplating processes are used to apply functional or decorative metal coatings to steel or iron surfaces. More recent developments are now also leading to an increasing demand for plastic electroplating, which uses plastic as the substrate for the metal coating.

The cleaner the rinse water, the better the pre-treatment. For the high-quality treatment of rinse water from a wide range of industrial productions, vacuum distillation has established itself as one of the most economical and sustainable methods. In case of H2O this also includes solutions for very high quality requirements and strict COD limits.
