Removal of Lead Contaminated Synthetic Wastewater by Ceramic Sludge Treated with Black Rice Husk
Abstract
Abstract The purpose of this research was to study of the efficiency of Lead heavy metal in Synthetic Wastewater by an adsorbent made from black rice husk (BRH) mixed sludge waste (S) from water treatment process in the ceramic plant of BRH-S(0:100), BRH-S (10:90), BRH-S (30:70), BRH-S (50:50), BRH-S (70:30), BRH-S (90:10) and BRH-S (100:0) wt%. The results showed the adsorbents of BRH-S (0:100), BRH-S (10:90) and BRH-S (30:70) could made as pellet. The equilibrium adsorption times were equal time of 20 hours in both of BRH-S (30:70) and BRH-S (10:90), while the BRH (0:100) was 24 hours. Results of the heavy metal removal percentages, from high to low efficiency, are as follow: RA-S (30:70), RA-S (10:90) and RA-S (0:100) are equal to 73.24%, 62.18% and 51.71%, respectively. Results of the pH values showed that there was a good adsorption at pH 5. From the study of Pb(II) removal efficiency at 25, 50, 75 and 100 ppm, it was found that the adsorption ratios of RA-S (30:70) performed the best adsorption. The result of this research was served a background data and an option for development of ceramic sludge treated with black rice husk for removal of Lead contaminated wastewater containing lead.
