BACKGROUND: The paper-making industry has developed rapidly in recent years. The paper-making process consumes much water and generates large amounts of wastewater. The reuse of the produced wastewater helps to save water consumption and reduce environmental pollution. Effective methods to treat and recycle paper-making wastewater are urgently sought. RESULTS: In this study, the performance of a full-scale internal circulation-anoxic/oxic (IC-A/O)-ultrafiltration (UF)-reverse osmosis (RO) membrane system for reclamation and reuse of paper-making wastewater was investigated. Results showed that the integrated system presented a stable and highly efficient performance. The effluent concentrations of chemical oxygen demand, total organic carbon, biochemical oxygen demand , NH 4 + nitrogen and total nitrogen were 12, 4, 0.3, 0.5 and 2.9 mg L −1. gas chromatographic-mass spectrometric results showed that the organic composition in each process of the IC-AO-UF-RO system varied significantly. Acute biological toxicity was obviously reduced, with an effluent toxic unit value of 3.11. The results of particle size distribution indicated that anaerobic granular sludge (around 3 mm) was formed in an IC reactor. Anaerolinea, Propioniciclava and Thauera were the main contributors to pollutant removal. Advanced treatment by the UF-RO system achieved complete removal of suspended solids, silt density index and turbidity with little hardness and conductivity in the final effluent, which allowed for reclamation of paper-making wastewater. CONCLUSION: Water reuse and energy recycling were successfully realized in the built-up IC-AO-membrane reactor system.

“…Another role for DIET and CIET is the bioremediation of toxic compounds from industry off streams, or already released in the environment. Recent studies investigated the possibility to apply CIET to improve the degradation of toxic compounds from the effluents of various industrial processes like: nitrobenzene -found in herbicides, insecticides and pharmaceuticals [61], azo dyes from the textile industry [62], solvents from the printing industry [63], chlorinated compounds (e.g. Refs.…”

Favorable interspecies associations prevail in natural microbial assemblages. Some of these favorable associations are cometabolic dependent partnerships in which extracellular electrons are exchanged between species. For such electron exchange to occur, the cells must exhibit electroactive interfaces and get involved in direct cell-to-cell contact (Direct Interspecies Electron Transfer/DIET) or use available conductive mineral grains from their environment (Conductiveparticle-mediated Interspecies Electron Transfer/CIET). This review will highlight recent discoveries and knowledge gaps regarding DIET and CIET interspecies associations in artificial co-cultures and consortia from natural and man-made environments and emphasize approaches to validate DIET and CIET. Additionally, we acknowledge the initiation of a movement towards applying electric syntrophies in biotechnology, bioremediation and geoengineering for natural attenuation of toxic compounds. Next, we have highlighted the urgent research needs that must be met to develop such technologies.
