Summary: This study investigates the membrane fouling mechanism in low pressure reverse osmosis (LPRO) and the effectiveness of electrocoagulation (EC) treatment in controlling membrane fouling. The results show that EC pretreatment can effectively reduce membrane fouling and enhance membrane flux by removing or decomposing the organic pollutants in pulp and paper wastewater (PPWW). The major foulants for LPRO membranes in PPWW are identified as humic acid-like and fulvic acid-like organics, which contain benzoic rings and carboxylic groups. EC treatment successfully removes these organic pollutants and improves the membrane fouling control.

Summary: This study identified KL-degrading Bacillus cereus from activated sludge and demonstrated their potential for degrading KL and reducing toxicity in paper mill effluent. The strain produced enzymes responsible for high KL degradation and decolorization, showing promise for pollutant removal in industrial wastewater treatment. Analysis techniques including SEM-EDS, UV-Vis, FTIR, and GC-MS were used to track the KL degradation process.

Summary: Three different pulp and paper mill sludge samples from South African mills were characterized to determine their suitability for various beneficiation pathways. The characteristics of the sludge varied depending on the pulping technique, raw material, and effluent treatment used. From the analysis, it was found that different beneficiation pathways were more suitable for each type of sludge based on their specific characteristics.

Summary: This paper develops a dynamic multi-objective optimization strategy to balance the treatment efficiency and cost of heavy metal wastewater treatment process. By defining the removal efficiency and optimizing the current reversing period, the difficulty of manually setting the current is addressed. An interval-adjustable control parameterization approach is proposed to simplify the optimization problem, and a heuristic method named multi-objective state transition algorithm is used for computation. The effectiveness of the model and optimization strategy is demonstrated through a successful implementation in a wastewater treatment plant in Chenzhou, China.

Summary: Migrating electric field-assisted electrocoagulation (MEAEC) is a three-electrode electrochemical system that utilizes waste flour-derived sponge biochar (SBC) as an adsorption electrode for efficient phosphorus removal from wastewater. The SBC electrode, with its low energy consumption and excellent effluent quality, demonstrated great potential in phosphate removal. The MEAEC system with SBC electrode achieved a high level of phosphate removal with much lower energy consumption compared to previous studies.

Summary: The aim of this study was to investigate the performance of advanced electrocoagulation (EC) process for the treatment of olive mill wastewater. Under optimum conditions, EC-PS and EC-PMS processes showed good efficiency in removing pollutants from the wastewater, but they were not sufficient to meet the discharge limits when used alone.

Summary: Due to the high pollution loads in the papermaking industry, a large amount of greenhouse gases are emitted during the wastewater treatment process. In order to reduce these emissions, an intelligent control scheme based on dissolved oxygen control has been developed. The simulation results show that the proposed hierarchical optimal proportional-integral control scheme can effectively reduce the greenhouse gas emissions compared to the open-loop operation.

Summary: This study investigated the oxidation of watered toxic waste from the pulp and paper industry in supercritical water-oxygen fluid, revealing that only CO2, CO, N2, and N2O were detected in volatile oxidation products at higher oxygen content. Increasing the oxygen ratio led to a decrease in phenols and chlorophenols produced, with 2,6-dichlorophenol and 2-chlorophenol being the most resistant to oxidation.

Summary: Over 400 million tonnes of board and paper are produced globally each year, generating 4.3-40 kg of sludge-like material, known as pulp and paper mill sludge (PPMS), per tonne of product. PPMS, with its high organic content and low toxicity, is being increasingly used as a soil amendment in agriculture. This review explores the benefits, potential impacts, and viability of land spreading PPMS, suggesting that risks can be mitigated and that the practice is environmentally responsible. However, further research is needed to assess long-term implications and the presence of emerging contaminants.

Summary: This study developed a synergetic and high-efficiency treatment of waste tantalum capacitors (WTCs) and polyvinyl chloride (PVC) using subcritical water process. The treatment significantly reduced the temperature and reaction time for metal tantalum recovery from WTCs, and improved the dechlorination efficiency of PVC. The optimized conditions resulted in 100% resin conversion efficiency of WTCs and 97.39% dechlorination efficiency of PVC. The interaction between decomposition products of WTCs and PVC produced a high level of benzoic acid.
