Wastewater management remains a major challenge in developing countries due to the lack of adequate infrastructure, making need for economically viable and efficient technologies that can be sustained by emerging economies imperative. The upflow anaerobic sludge blanket (UASB) reactor represents an low-cost technology produces by-products from which valuable resources recovered. This study asse...

The aromatic and dark-colored spearmint essential oil wastewater (SEOW) generally contains a large amount of organic matter, including chemical oxygen demand (COD), phenolic compounds, and inorganic contents. In this study, the pollutant removal performance and biogas production rate of an up-flow anaerobic sludge blanket (UASB) reactor used for the treatment of SEOW were investigated. During t...

An integrated chemical-physical-biological treatment concept for the low-cost treatment of domestic wastewater is proposed. Domestic wastewater was subjected to a chemically enhanced primary treatment (CEPT), followed by treatment in an upflow anaerobic sludge blanket (UASB) reactor. In addition, a regenerable zeolite was used to remove NH4+, either after CEPT pretreatment or after biological t...

The current paper assesses the reliability coefficients of fifty six low-cost, full-scale wastewater treatment plants, including nine different treatment technologies for wastewater reuse in aquaculture and agriculture in northeast Brazil. This was carried out with the aim to evaluate alternatives for sustainable wastewater reuse in communities experiencing water scarcity. The technologies eval...

Water-soluble copolymers such as polyvinylpyrrolidone and polyvinyl alcohol have been widely used detergents, paints, chemical intermediates in many industrial processes, leading to environmental concerns associated with high-volume organic compound wastewater. Therefore, this study, a combined upflow anaerobic sludge blanket (UASB) reactor downflow hanging sponge (DHS) biosystem has applied fo...

Performance of a rotating biological contactor (RBC) in treating municipal wastewater from primary sedimentation basin and anaerobically treated industrial effluent from an upflow anaerobic sludge blanket (UASB) reactor was investigated. The 280-L six-stage RBC pilot was operated at different organic loading rates and biodisc speeds. The overall removal efficiencies of soluble BOD decreased wit...

UNLABELLED BACKGROUND A modified laboratory-scale upflow anaerobic sludge blanket (UASB) reactor was used to obtain methane by treating hydrous ethanol vinasse. Vinasses or stillage are waste materials with high organic loads, and a complex composition resulting from the process of alcohol distillation. They must initially be treated with anaerobic processes due to their high organic loads. ...
