Production of pure and laboratory water with guarantee and tradition

DEMI - for technological demiwater preparation

DEMI is a device for technological demiwater preparation. Performance and quality parameters are according to customer requirements.

Demi-stations of type series DEMI are designed for demineralized water production. No chemicals are used, therefore problems with waste water neutralization are eliminated.

Demineralization of inlet raw water proceeds on reverse osmosis principle. Mechanical impurities in raw water are entrapped with a filter which is part of basic equipment. Water pretreatment for RO is solved individually and completed with particular equipments according to specific composition of raw water.

Inlet medium is drinking water acc. to Council directive 80/778/ECC, or possibly water specified by client.

Demi-stations are supplied in two versions:

  1. Basic model:
    • Device without controlling measuring microprocessor control unit
    • Floor type only without outer steel-sheet covering
  2. Fully automatic operation with microprocessing control system

Utility areas:

  • Chemical industry
  • Galvanizing plants
  • Neutralizing stations
  • Food industry
  • Boiler houses
