Experience in applying reverse osmosis as the fourth stage of treatment
With the support of the Federal Ministry of Education and Research of Germany, a project was created called «MULTI-ReUse» (www.water-multi-reuse.org). The project aims to develop and test modular plants combining various purification technologies, as well as demonstrating the possibility of obtaining from the sewage water of the highest quality. The project participants conducted pilot tests using two different types of membrane plants for further comparison. During the operation of the reverse osmosis unit, the LewaPlus® software developed by LANXESS was used, which was used to assess the effectiveness of the technology. The article presents and illustrates the results of the study.
