Sterile phosphate as a novel calcic adsorbent for phosphorus removal from wastewater.

Sterile phosphate (SP) was investigated for phosphorus removal from wastewater using batch adsorption experiments. The novel adsorbent is a mining by-product obtained from the phosphate mining plants having a strong affinity with phosphorus ions present in wastewater. The results of the batch adsorption experiments indicated that 30 min of contact time between the adsorbent and wastewater was sufficient for attaining equilibrium.
