Effects of chloride ions on electro-coagulation-flotation process with aluminum electrodes for algae removal.
The results showed that the addition of Cl(-) ions had a promoting effect on the algae removal in terms of both the cell density and chlorophyll-a, which could be attributed to the following two reasons:Active chlorine was demonstrated to be effective for the inactivation of algae cells with the aid of the electric field in the ECF.

Ultrafiltration membrane fouling caused by extracellular organic matter (EOM) from Microcystis aeruginosa: Effects of membrane pore size and surface hydrophobicity
Abstract This study focused on the effects of membrane pore size and surface hydrophobicity on ultrafiltration (UF) membrane fouling caused by extracellular organic matter (EOM) from MicrocystisExpand
Characteristic analysis on temporal evolution of floc size and structure in low-shear flow.
Fragmentation followed by reformation seemed to be more effective in forming larger and more compact aggregates than the restructuring process due to erosion and reformation, which may provide useful insights for the design of flocculation reactors. Expand
Effect of PAC addition on immersed ultrafiltration for the treatment of algal-rich water.
It was identified that PAC reduced the concentrations of carbohydrates and proteins in the reactor due to decreased light intensity, as well as the MC-LR(eq) concentration by PAC adsorption. Expand
Highly efficient removal of bivalent heavy metals from aqueous systems by magnetic porous Fe3O4-MnO2: Adsorption behavior and process study
Abstract In this study, magnetic Fe3O4-MnO2 nanoplates were successfully synthesized by a facile hydrothermal process in order to remove bivalent heavy metals from water. The Fe3O4 part facilitatedExpand
Copper removal and microbial community analysis in single-chamber microbial fuel cell.
The mechanism analysis demonstrated that microbial electrochemical reduction contributed to the copper removal with the products of Cu and Cu2O deposited at biocathode and the microbial community analysis indicated that microbial communities changed with different copper concentrations. Expand
Influence of flocs breakage process on membrane fouling in coagulation/ultrafiltration process—Effect of additional coagulant of poly-aluminum chloride and polyacrylamide
Abstract The additional coagulant dosing strategy was applied in a coagulation–ultrafiltration (UF) process for treatment of drinking water. When poly-aluminum chloride (PACl) dose was set as theExpand
Chemical cleaning of fouled PVC membrane during ultrafiltration of algal-rich water.
Scanning electronic microscopy and atomic force microscopy analyses demonstrated that 500 mg/L NaOH could change the structure of the residual foulants on the membrane, making them more tightly attached to the membrane surface, which might be responsible for the negligible membrane permeability restoration after NaOH cleaning.

Using bacterial catalyst in the cathode of microbial desalination cell to improve wastewater treatment and desalination.
The biocathode MDC, consisting of carbon felt and bacterial catalysts was tested and proved to be a promising approach for efficient desalination of salt water. Expand
Bioflocculation of photo-fermentative bacteria induced by calcium ion for enhancing hydrogen production
Abstract The applications of photo-fermentative bacteria (PFB) for continuous hydrogen production are generally subjected to a serious biomass washout from photobioreactor, resulting from poorExpand
