Abstract P-control technologies from municipal wastewater are based on ‘‘destructive’’ methods leading to formation of solidphases (sludge) that are disposed-off in controlled landfills. Non-destructive methods, based on selective liquid–solid separations allow for removal of pollutants and their recovery to the same and/or related productive lines. REM NUT, an ion exchange based process, removes selectively nutrients (HPO2 4 , NHþ4 , Kþ) present in biologically oxidised municipal effluents and recovery in the form of struvites (MgNH4PO4; MgKPO4), premium quality slow release fertilisers. The main limitation, for the extensive application of the process, is the availability of specific anion exchangers for selective removal of phosphates. The paper illustrates laboratory and field experience carried-out at Massafra (S.E.

Abstract
P-control technologies from municipal wastewater are based on “destructive” methods leading to formation of solid-phases (sludge) that are disposed-off in controlled landfills. Non-destructive methods, based on selective liquid–solid separations allow for removal of pollutants and their recovery to the same and/or related productive lines. REM NUT®, an ion exchange based process, removes selectively nutrients (HPO42−, NH4+, K+) present in biologically oxidised municipal effluents and recovery in the form of struvites (MgNH4PO4; MgKPO4), premium quality slow release fertilisers. The main limitation, for the extensive application of the process, is the availability of specific anion exchangers for selective removal of phosphates. The paper illustrates laboratory and field experience carried-out at Massafra (S.E. Italy) Wastewater Treatment Plant (MWTP) with a revisited “P-driven” version of the REM NUT® scheme and the use of a new phosphate-selective sorbent developed at Lehigh University, PA, USA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
