Abstract
Polyethylene glycol diacrylate (PEGDA) hydrogel microsphere was synthesized by UV-assisted reverse emulsion polymerization as an efficient adsorbent for water purification. Optical microscopy and TEM proved its spherical and hollow structure, while XRD pattern proved that it was amorphous with limited crystallinity. Abundant oxygen-containing functional groups such as hydroxyl were detected by FTIR. The hydrogels exhibited low swelling capacities ranging from 0.19 to 0.77 g/g in water and would decrease in salty solutions. The effects of operation parameters on the bisphenol A (BPA) adsorption were studied, including the polymer composition between PEGDA and polyethylene glycol methacrylate (PEGMA), initial concentration of BPA, pH, and operation temperature. The resulting hydrogel, especially for PDM2 (the ratio between PEGDA and PEGMA is 2), was able to effectively enrich BPA in water. The adsorption capacity was nearly stable below pH 8.0 and decreased when beyond 8.0. Thermodynamic parameters reflected that BPA adsorbed by hydrogel was a spontaneous (ΔG0 < 0) and exothermic (ΔH0 < 0) progress. The adsorption capacity increased with the increase of the concentration of NaCl, exhibiting salinity-enhanced adsorption capacity driven by hydrophobic force. Excellent results were also achieved by applying hydrogel for spiked real surface waters, which accounted for more than 91% compared to simulated solution. As-prepared hydrogel was expected to be good candidate for treatment of endocrine disruptors with lower solubility in water.

Abstract
In the present research, an experiment was conducted with the objective of optimization of the role of earthworms in alleviating the bioclogging of a horizontal subsurface flow vermifilter (HSSFVF), caused due to the application of organics rich brewery wastewater. In this experiment, for the optimization of bioclogging of the vermifilters, the Box-Behnken Design (BBD) and response surface methodology (RSM) were involved. Hydraulic loading rate (HLR), influent COD and earthworm density (EWD) are the variables against which the bioclogging of the HSSFVF has been optimized. EWD of 9475 earthworms/m3, HLR of 1.84 m3/m2-d and influent COD of 3701 mg/L have been observed as the optimized values for the minimum bioclogging in the vermifiltration of brewery wastewater. At this optimum boundary conditions, the reduction in hydraulic conductivity was obtained as 1.49%, against the predicted value of 1.67% based upon the BBD model. The verification of the model against real brewery wastewater yielded insignificant error and thus very strongly portrays the suitability of the derived BBD model. The study indicates that the bioclogging from the vermifilters can be minimized, if the variables are optimized using the response surface methodology.
