Efficient phosphate recovery as vivianite: Synergistic effect of iron minerals and microorganism

Vivianite is a promising phosphorus recovery solution that has the potential to simultaneously relieve the phosphorus shortage and phosphorus pollution. By producing vivianite, dissimilatory iron reducing bacteria may substantially enhance...

Algae control in oligotrophic surface water under the joint effect of nutritional competition and microbial algae-lytic substance

Harmful algal abnormal proliferation presents the most severe threat to the quality of oligotrophic surface water even in source water such as South-to-North Water Diversion Project in China. A novel...

Sustainably closed loop recycling of hierarchically porous polymer microbeads for efficient removal of cationic dyes

Herein, we designed and fabricated a hierarchically porous crosslinked polymeric microbead (PCP) with high density of functional groups for selective adsorption of cationic dyes from water. On account of...

Enhancing Ammonium Oxidation Fluxes and Nitritation Efficiencies in MABRs: A Modeling Study

The membrane aerated biofilm reactor (MABR) is a novel technology based on gas-supplying membranes that supply dissolved O2 (DO) to biofilms growing on the membrane surface. The counter-diffusion of dissolved...
