Phosphorus removal via reed-planted filters

All plants assimilate phosphates for their growth and reproduction. Thus, among wastewater treatment processes, one of the favored solutions is the implementation of physico-chemical dephosphatation within a series of reed-planted filters. Indeed, its release levels are excellent concerning carbonated pollution and nitrification. However, despite a promising start, plants cannot provide cheap solutions in terms of surface and furthermore, the performances in terms of phosphorus retention are minimal on the long term and even insufficient. Other processes aimed at increasing the retention of phosphorus are available including the use of minerals such as the apatite.
