- Abstract
Approximately 10,000 m³/day of untreated wastewater is produced during phosphate beneficiation at Eshydia phosphate mine in southern Jordan. The effluent contains 21 wt% phosphates (PO) and 12-14 wt% solids. Dissolved air flotation (DAF) and subsequent nanofiltration (NF) were investigated as potential treatment methods. DAF combined with the use of a commercial flocculant effectively removed the suspended solids and decreased total dissolved solids (TDS) by 50 %; NF effectively treated the DAF effluent and produced water with only 860 ppm TDS. The treated water can be recycled for use by Eshydia phosphate mine or for irrigation.
