Chriwa Wasseraufbereitungstechnik GmbH - Research and Development

To keep the applied technologies up to date Chriwa networks with universities and relevant institutions. This ensures a lively exchange of experiences in both directions.

In this context, Chriwa takes regularly care of degree dissertations, as well as bachelor and master degrees with a practical approach.

Moreover, well-known water treatment processes are enhanced by Chriwa and implemented in new fields of application. We like to emphasize the use of our inert filter material ChriwaFilt - filter materials for enhanced reduction (without chemical dosage) of increased concentrations, such as:

  • Arsenic
  • Barium
  • Fluoride
  • Uranium
  • Radium

 In addition, Chriwa develop their own devices in the electronic / metrological field, such as:

  • Delta-pH meter for evaluation of lime and carbonic acid equilibrium
  • CMT (Chriwa multi measuring transmitter) for simultaneous recording
    and reporting of multiple readings with a single amplifier

 There are other developments in the Chriwa group of companies, such as:

  • Chlorine electrolysis cell for on-site production of high purity chlorine bleach

Finally, we provide our customers with tailor-made

  • Process visualization systems with comprehensive documentation and evaluation functions
