我们针对 "无废水生产 "主题的指导手册。

工业废水含有各种各样的污染物。例如，这些可能是来自金属加工厂的重金属，来自零件清洗的脂肪和油，或来自制药业的药物残留物 - 废水与工艺本身一样不同。市场上有许多不同的工业废水处理工艺--都有各自的优势和劣势。以下是对市场上最常见的方法的概述。

工业废水是指工业生产过程中产生的废水。根据其来源，它被不同的污染物所污染，必须在排入公共管路之前进行处理。

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.

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.
