This paper discusses the effect of organic and inorganic contents of wastewater on the removal of dissolved organic carbon (DOC) by powder activated carbon (PAC). Each single component of organic compounds in the presence and absence of inorganic compounds was described using the mathematical model through a series of isotherm and batch experiments. Batch experiments on PAC adsorption were conducted with three different types of PAC. The synthetic wastewater used was prepared by a known quantity of organic and/or inorganic compounds. The removal efficiency of DOC in synthetic wastewater was studied to mathematically describe the overall adsorption isotherms. The determination of the kinetic and equilibrium parameters for the target organic compounds in synthetic wastewater and the effect of inorganic compounds on DOC adsorption were studied. The experimental results showed that (i) wood based PAC produced the better effluent quality in terms of DOC; (ii). the DOC adsorption capacity of organic compounds d remove DOC dominantly at the early stage of batch experiments; (iv) the simultaneously biodegradation (of a first order reaction) is essential for the simulation results due to biodegradation was observed along with adsorption after 2 days of batch experiments. |
