Membrane systems are process-efficient separation systems for water, process and waste water treatment that can be configured depending on the use. Depending on the separation or treatment task, different membrane materials are used for the process. HST systems are characterised by system-technology construction in flexible standard versions as well as comprehensive and complete process monitoring. They are produced as microfiltration, ultrafiltration or desalination systems, depending on the treatment goal for mobile or stationary use.
