Reverse Osmosis (RO) for Industrial Applications

Global water shortages due to droughts, population growth and stringent enviromental discharge regulations have created increasing interest in water reuse and recycling. Pressured membrane processes, in particular, reverse osmosis (RO), are well-established technologies in water treatment. However, the drawbacks of RO membrane filtration include high energy consumption and operational costs.

In addition, the volume of RO concentrate (reject) produced by RO systems is significant and, in most cases, contain high levels of contaminants. Typical TDS concentrations in RO concentrate are often in the range of 30,000 – 50,000 mg/ litre. The salts in the solution can range from highly soluble sodium and potassium salts to less soluble or reverse-soluble calcium and barium salts.

The volume of RO brine (concentrate) produced by the RO systems is significant and, in most cases, contains high levels of contaminants.

Our membrane-based solutions are less energy intensive when compared to other treatment technologies, therefore improving operational expenditures (OPEX).

Berghof Membranes delivers robust chemicalresistant membranes and solutions capable of reducing the RO concentrate volume and, in combination with other technologies, can achieve Minimal Liquid Discharge (MLD) or even Zero Liquid Discharge (ZLD), helping industries make the transition from linear to circular economy.

Polishing and Recovery

Tubular UF membranes are ideal for the separation of effluent streams, further removing any remaining suspended solids. In certain applications, they can also enable the recovery of valuable materials such as metals and proteins, for example.
