Biostructure was prepared by mixing aggregates, sand, granular activated carbon (GAC), blast furnace slag (BFS), zeolite and ordinary Portland cement in specified ratio. Optimisation of its components mix ratio was carried out using statistical approach. The study shows that Biostructure with a porosity of 21% and compressive strength of 8.4MPa under optimised components mix ratio (77.00% aggregates, 10.00% sand, 10.00% cement, 1.00% GAC, 1.00% zeolite and 1.00% BFS) was able to remove the COD of petrochemical wastewater up to 75.00% (13,000mg/L COD) in 16days. The adsorption equilibrium was found to be better fitted to the Langmuir isotherm model compared to the Freundlich model. The study indicates that the Biostructure prepared is a potential adsorbent for the treatment of petrochemical wastewater.
