Selective ion exchange plants

Plants for treatment of certain types of metalliferous wastewater. This type of plant is used in industries where the residue of heavy metals is too large to fulfil the authorities’ requirements for wastewater disposal. Selective ion exchange is a supplement to a conventional treatment plant.


It is possible to obtain discharge values of less than 0.1 mg/l per metal for divalent metals.

Plant description

Flow rates for standard modules: 0.5-10 m³/h. Selective ion exchange plant, type SEL-FNS, is produced in five standard modules - all with automatic regeneration.

The installation consists of selective ion exchange plant, multimedia filter, and carbon filter. Application: Removal of heavy metals by production of printed circuit boards.
