dc.description.abstractThe feasibility of continuous phosphate recovery, by adsorption on powdered Ca-activated zeolite (PAZ), was assessed in a hybrid sorption membrane ultrafiltration (UF) system. The objective was to explore the influence of process parameters such as initial P(V) concentration, pH, and PAZ dose on P(V) recovery from a tertiary treatment effluent. The hydrodynamic parameters of the UF operation were also evaluated as a function of the PAZ dose. The P(V) recovery profiles as a function of the initial P(V) concentrations, at pH 8 and 2.5 gpAz/L, indicated that the sorbent was not saturated, and recoveries reported were 1.8 +/- 0.2, 5.7 +/- 0.3, and 47.2 +/- 2 mg P(V)/gpAz for 10 +/- 1, 25 2, and 100 +/- 6 mg P(V)/L, respectively. The increase of the pH of the feed solution from 8 to 9 increased the P(V) recovery up to 70 4%. A P(V) fractionation protocol of the loaded samples confirmed that the phosphate -sorption process involves the formation of calcium phosphate mineral forms
