Membrane technology is a physical process for separating mixtures of substances, in which the membranes used function similarly to a filter. With membrane technology, water is cleaned in such a way that it can be reused. The substances filtered out of the water can also be reused in industry. Multiple use of the water significantly reduces the amount of wastewater, which is cost efficient.

Greentech plans and builds membrane systems that are optimally tailored to the respective application. We offer a full portfolio of Membranfiltration solutions from tailor-made and compact units to large systems. Depending on the type and quantity of the substance as well as your requirements for the pure water, we use four membrane technologies that are similar in structure, differ mainly in their filtration sharpness.

Application fields:

  • - Water reuse
  • - Beverages and groceries
  • - Cosmetics and pharmaceutical industries
  • - Seawater desalination
  • - Production of ultrapure water
  • - Soft water: softened water with a low lime content
  • - Boiler feed water
  • - Well water treatment: for an independent water supply.
  • - Process water and service water treatment
  • - Recovery of water in the chemical industry
  • - Post-treatment of wastewater

We support you in filter selection, dimensioning and process optimization. It is always our goal to determine the best possible filtration performance for the respective application.

membran filtering



Microfiltration is a physical separation process that removes contaminants such as suspended solids, fats, and microbes from process fluids.



Our ultrafiltration systems remove the finest particles and turbidity from the water and reduce microbiological pollution such as bacteria, viruses and parasites



Our compact nanofiltration systems can be adapted to the various requirements of the pure water quality and can also be used in two-stage operation.


Reverse osmose

Our reverse osmosis systems can be adapted to the various requirements for pure water quality and can also be used in two-stage operation


Membrane bioreactor

Membrane Bioreactor Technology (MBR) is an efficient and most advanced technology for municipal and industrial wastewater. treatment process which combines high-efficiency membrane separation technology with conventional activated sludge process
