Cover Story: Produced strontium (Sr) is a radioactive waste product of nuclear power plants and may cause bone cancer and leukemia. Even though naturally occurring Sr has relatively low toxicity, excessive exposure may lead to bone growth problems in children. This paper addresses natural groundwater with high Sr and natural organic matter (NOM) content from Eslalei, northern Tanzania. Sr removal was investigated using a pilot-scale nanofiltration/reverse osmosis (NF/RO) system with an underlying interest in Sr-NOM interactions. The impact of applied pressure and groundwater pH on the membrane system performance was investigated. Results demonstrate that the NF/RO system has a very high capacity for Sr and NOM removal in real groundwater, and appropriately high applied pressure and acidic pH conditions could enhance performance.
