Chemical Cleaning of Utafiltration Membrane after Treatment of Oily Wastewater

Two-stage anaerobic process treating high concentration methanol wastewater and

In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...

Anaerobic Wastewater Treatment Process

Anaerobic wastewater treatment differs from conventional aerobic treatment. The absence of oxygen leads to controlled conversion of complex organic pollutions, mainly to carbon dioxide and methane. Anaerobic treatment has favourable effects like removal of higher organic loading, low sludge production, high pathogen removal, biogas gas production and low energy consumption. Psychrophilic anaero...

Feasibility of electrochemical oxidation process for treatment of saline wastewater

Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...

Recurrent High Order Neural Network Modeling for Wastewater Treatment Process

Due to the multi-variable, nonlinear, large time delay and strong coupling features of the wastewater treatment process, a recurrent high-order neural network is used to model the key water quality parameters(Chemical Oxygen Demand, Biological Oxygen Demand, Suspended Solid and Ammonia Nitrogen) for the wastewater treatment process, and the neural network is trained by an filtering algorithm. O...
