Solutions for Water & Wastewater

Smart water treatment technologies.

Water treatment applications

Alkaline Wastewater Neutralisation

pH reduction with CO2

Biological Process Intensification

Increase the activity of the biomass. Temporary or permanent increase in performance.

Reduction of filamentous biomass

Increase the health of the mud.

Foam and odor reduction

Maintain DO levels with little stirring.

Reduction of micro pollutants

By oxidation with O3 in combination with filtration or adsorption.

Sludge Production Minimisation

Disintegration by ozone

Sludge treatment in the wastewater sector

Disintegration with O3

N2 Inerting

Applications in drinking water treatment

Remineralization with CO2

Remineralization/ Hardening/ Softening of the lime-carbonic acid balance with CO₂

Deferrisation/ demanganisation with O2

Oxidation/ disinfection with O3 (ozone)

Gases we use for water treatment

Industrial gases for water and wastewater treatment are oxygen for aeration, carbon dioxide for pH control, ozone for intensive chemical oxidation, and nitrogen for inerting.
