Curieau®
Membrane filtration systems extract small suspended solids and part of the dissolved matter in water.
By using this technique, wastewater can be upgraded to drinking water.
For the extraction of suspended solids, high capacity course-media-filters are used.
The high capacity course-media-filters from AQUA Industrial Watertreatment can be executed with:
- Single-, double- or multilayer (for instance sand and sand-anthracite)
- Atmospheric or high pressure
The Curieau® system consists basically of the following process steps:
- Sand filtration: the first treatment step is needed for removal of remaining solids in the effluent of the existing biological waste water treatment plant.
- Oxidation tank: the second step makes sure any polymer residues are oxidized by means of a chlorination, so these will not be harmful to the rest of the process.
- Activated carbon filter: to remove any free chlorine residues after the chlorination tank, water is lead through activated carbon.
- Reverse osmosis installation: water is pressed through special membranes. Only water can pass these membranes: ions and bacteria stay behind.
- Marble filter: the marble filter adds hardness to the water, to make it potable again.
- UV disinfection: the last step in the treatment process is UV disinfection to removed any remaining bacteria to prevent biological activity.
