With the rising demand for renewable energy and environmental protection, anaerobic digestion of biogas technology has attracted considerable attention within the scientific community. The effect of physico-chemical pretreatment on cellulose degradation followed by fungal treatment by Aspergillus terreus and Trichoderma viride to treat cellulosic biomass for enhancing its digestibility was inve...

In this study the feasibility of treating dyeing wastewater with sulfate reducing granular sludge was explored, focusing on decolorization/degradation of azo dye (Procion Red HE-7B) and the performance of microbial consortia under alkaline conditions (pH=11). Efficiency of HE-7B degradation was influenced strongly by the chemical oxygen demand (COD) concentration which was examined in the range...

Sanitary landfilling is still considered worldwide as one of the most common methods applied for management municipal solid waste. As a consequence, vast amounts landfill leachate are generated annually, which characterized by variability in physicochemical composition, owing to stabilization process that occurs over years. However, sustainable challenging issue, due diverse chemical compositio...

Abstract This is the second of three papers dealing with metal-bearing circumneutral mine drainage from inactive Rico-Argentine site located at an elevation ≈ 2740 m (9000 feet) in San Juan mountain range southwestern Colorado. paper evaluates two years treatment using a passive system that included vertical-flow engineered biotreatment cell. The collapsed St. Louis Tunnel (SLT) discharges wate...

Due to its high lipid content and intricate constitution, food waste poses a considerable challenge for biotreatment. This research aims investigate the potential influence of diverse species on anaerobic fermentation, induced by varying dietary patterns observed in distinct regions. The investigation involved incorporating 5% (w/w) beef tallow, mutton fat, soybean oil, peanut rapeseed separate...

Nitrate and arsenic often co-exist in groundwater sources. Reverse osmosis, electrodialysis, ion exchange are the commonly implemented technologies for nitrate removal. Compared to these that generate high-strength waste streams, biological treatment converts innocuous nitrogen gas without producing a concentrated waste. When water source, combining biotic process removal with an abiotic (i.e.,...
