الملخص الإنجليزي

In this study the dried raw waste activated sludge (DRWAS) was used as a biosorbent material to remove Pb(II), Cd(II) and Cr(III) from simulated wastewater with different operating conditions to optimize the heavy metal removal process by statically analyzed tool was used to optimized the removal efficiency according to change operating conditions using response surface methodology (RSM).

The ranges of these parameters were initial metals concentration 10–50 mg/L, pH 2–5, contact time 10–240 min, temperature 25-40 °C, Agitation speed 50-200 rpm, and biomass loading 0.5-6 g/L.

Removal efficiency model was obtaining with high significant and low p-value with predication values of 99%, 85% and 78% for Pb(II), Cr(III) and Cd(II) respectively.

The study clearly showed that DRWAS was promising low cost biosorbent to remove heavy metals.
