Treatment technologies needed to reduce the pollutant load of chemical industry effluent have been found to involve exorbitantly high costs. The present investigation aimed to treat the wastewater from chemical industry by cost effective sequential anaerobic-adsorption treatment. Wastewaters from chemical industry that are rich in biodegradable organics are tested for anaerobic treatability. The efficiency of anaerobic reactor is relatively lower 79.3%, and therefore post treatment of effluent was done by adsorption using Poly vinyl alcohol coated Datura stramonium (PVAC-DS) as an adsorbent. An overall COD removal of 93.8 % was achieved after sequential Anaerobic-Adsorption treatment, which lead to a better final effluent and a more economical treatment system.
