| Summary: | Heavy metals are widely used in textile industries and significant losses occur
during the manufacturing and processing of textiles, and these lost heavy metals are
eventually discharged in the effluent. Activated carbon (AC) is preferred adsorbent
for removal of pollutants from aqueous and liquid phase. In this study, adsorbent
fiom palm kernel shell (PSAC), an agricultural waste product were used to remove
selected heavy metals which are copper, iron and zinc from textile wastewater. To
investigate the effectiveness of palm shell activated carbon in removing heavy
metals in textile wastewater, three reactors have been used for textile wastewater
treatment. Reactor A treats textile wastewater using commercial activated carbon
(F'AC), Reactor B treats textile wastewater using activated carbon from palm shell
(PSAC), while Reactor C acts as a control. The three reactors were tested against
time with textile wastewater samples taken hm a textile factory, RAMATEX
Industries. The effectiveness of both activated carbon was obtained from the quality
of effluent. The laboratory assay revealed that Reactor B was found to be better than
Reactor A in removing all selected parameters. Reactor B had achieved 17.2%
copper removal, 99% iron removal, and 50% zinc removal thus proving its ability to
adsorb heavy metals more economically. Therefore it is concluded that PSAC have
a potential to be an alternative low cost adsorbent to replace the conventional AC by
optimizing the activation procedures, considering the contaminants to be removed. |
