Membrane processes

Resource-saving water treatment, recycling and reuse

In the past, use of membrane processes for water treatment was often only economically viable in drinking and process water production, as an alternative to filtration and desalination. However, these processes are now becoming increasingly important in wastewater recycling. Increasing water scarcity, rising water costs and the requirement to reduce water footprints are reinforcing this trend.

We use various Envopur® membrane processes, depending on the task involved, sometimes in combination with other technologies, such as ultrafiltration, reverse osmosis, nanofiltration, electro-deionisation (EDI) and Biomar® membrane bioreactors.

Our experts work with you to determine the appropriate plant technology for your specific requirements in terms of water treatment, water recycling, water reuse and even zero liquid discharge (ZLD).
