TL;DR: In this paper, a central composite design (CCD) was used to optimize the operating parameters of the Fenton process in removing recalcitrant organics from POME by using a response surface methodology (RSM) module in the Design-Expert ® software.
Abstract: Post treatment palm oil mill effluent (POME) is typically non-biodegradable and contains high organic and inorganic matter. This study aims to optimize the operating parameters of the Fenton process in removing recalcitrant organics from POME by using a central composite design (CCD), which is a response surface methodology (RSM) module in the Design-Expert ® software. Important parameters such as reaction time, H 2 O 2 and Fe 2+ ion concentrations, and pH were empirically determined and successfully optimized via RSM. Significant statistical quadratic polynomial for color and COD removal efficiency were obtained via regression analyses R 2 , (0.81 and 0.70) for color and COD, respectively. The highest results were 97.36% removal for color and 91.11% removal for COD at pH 3.5 and 30 min of reaction time. Numerical optimization based on desirable functions was employed; 92.1% of color and 85.1% of COD were removed efficiently at pH (3.0–5.0) with a final pH of 2.85 (after reaction settlement), 4.57 g/L H 2 O 2 and 1.88 g/L Fe 2+ ions concentration, respectively, and 30 min of reaction time at 120 rpm agitation rate. The result showed that the Fenton process, at an accurate level, may be used as an effective technology for the post treatment of POME before final discharge into a nearby water body.

TL;DR: In this paper, the surface morphology and surface functional groups of adsorbents significantly changed after treatments and resulted in different Hg0 adsorption performances, and the experimental breakthrough data for all the adsorbent produced a good fit to the pseudo-second order kinetic model.
