The efficiency of P extraction by the ,alkaline wastewater, (0.5〜1.0 mol L-1 ) was similar to that of extraction with a pure NaOH (also 0.5〜1.0 mol L-1) at 70℃. The P component in the residue after treating with an ,alkaline wastewater, was extracted with Fe ion containing ,acidic wastewater, at pH=0.1~2.0 at a room temperature.

Many industries, such as textile, paper and pulp, ,dyeing, and ,printing, industries, are causing water pollution by discharging their effluent into water bodies (Christensen et al. 2009). The textile industry is one of the major industrial sectors which consumes high volumes of water for its various processes and consequently discharges large amounts of highly polluted water ( Patel & Shah 2013 ).
