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).

International project implemented – despite pandemic

In the meat industry, for example, wastewater with a high organic load is produced during the cleaning of production plants.

The hidden potential in dairies

Dairies use water for many different stages in the production process. There are often potential savings to be made here in terms of resources and energy. To achieve this, however, an integral view is required, since the cycles used in dairies, which have often grown over the years, are highly…
