Technology offer : Phosphorus removal from wastewater using reed filters and apatites
Our method of removing phosphorous from wastewater using reed beds is innovative due to its apatite base. These natural minerals found in natural calcium phosphate minerals are interesting for two reasons:
- They improve phosphate retention due to their high potential for phosphate removal (kinetic and accumulation rates)
- They add phosphate to waste material, helping to increase its recycling value.
Our measure provides increased capacity for optimal and sustained retention without increasing the footprint of the purification device, using chemical reagents or creating sludge.
Any phosphorous dissolved in the processed wastewater crosses the filter and is retained by a process of adsorption - precipitation when it comes into contact with the apatite, allowing the water to meet discharge standards.
