Diagnosis of an anaerobic pond treating temperate domestic wastewater: An alternative sludge strategy for small works [PDF]

, 2014
An anaerobic pond (AP) for treatment of temperate domestic wastewater has been studied as a small works sludge management strategy to challenge existing practice which comprises solids separation followed by open sludge storage, for up to 90 days. During

Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

Carbon Energy, EarlyView.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...

Simultaneous treatment of garbage and domestic wastewater using an improved domestic wastewater treatment tank.

Journal of Environmental Conservation Engineering, 2001
本研究では, 厨芥を水を加えながらディスポーザーにより破砕した後, 改良型の合併処理浄化槽に投入する実験を行い, 厨芥と生活排水の同時処理について検討した.その際に, 合併処理浄化槽内の水の移送方法を変化させ, 最適な運転条件に関する検討を行った.実験結果から, 厨芥投入後の処理水質は, 投入前の処理水質と比較して, ほとんど変化はなかった.また処理水質は, 一般的な活性汚泥法よりも低い値を示した.本実験における最適な運転条件は, 最終沈殿槽からし尿槽への水の移送をエアーリフトを用いて行い, それ以外の水の移送は全てオーバーフローで行う方法であった.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

The Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...
