Wastewater

Seawater desalination is an increasingly common means to meet the demand for freshwater. Resulting wastewater discharges can, however, impact biota of the surrounding environment. Concern exists that interactive effects specific to the outputs of each desalination plant may result in unique impacts d

The microbial desalination cell (MDC) is a newly-developed technology which integrates the microbial fuel cell (MFC) process and electrodialysis for wastewater treatment, water desalination and production of renewable energy. Due to free energy requirements and environmentally friendly technologies,

A new configuration of electrodeionisation with a bipolar membrane (EDI-BP) with a segment electrode was proposed for the treatment of simulated dilute Ni2+-containing wastewater. The feasibility of EDI-BP was analysed and experimentally validated, and its current density distribution was studied sim

Discharge of liquid and solid waste from Jimma town has resulted in a gradual degradation of the quality of the river water feeding the Gilgel Gibe dam, which was constructed for the development of the hydroelectric potential of the Gilgel Gibe River. In general, wastewater is not treated, which mak

An automatic vacuum membrane bioreactor (AVMBR) equipped with an on-line air–water–chemicals backwashing system was developed for a purpose of the reclamation of domestic wastewater (300–800 mg-COD/L) and traditional Chinese medicine (TCM) wastewater (259–12775 mg-COD/L). The experimental setups wer

The paper reports on the results of treatment of wastewater from the bottling of water and soft drinks with a membrane bioreactor (MBR) pilot plant. The existing conventional activated sludge process could not produce effluent suitable for discharge due to significant fluctuations of wastewater comp

The effect of pH, biosolid dosage, initial copper concentration, and contact time on copper removal from aqueous solutions using biosolids (waste sludge cake) was investigated through batch experiments. The copper removal increased by time and initial metal concentrations. The equilibrium time was a

The main objective of this work was to determine the impact of various backwash scenarios on fouling in a pilotscale submerged membrane bioreactor (MBR) aerobically treating domestic wastewater. A total of seven different backwash scenarios were tested. The degree of membrane fouling was determined

The main interest of the methodology for the investigation of wastewater reclamation and reuse systems which is proposed in this paper is that all costs and benefits (social and private) are considered in the economic and technological analysis. This general concern allows an improvement in the desi

For small settlements sanitation, constructed wetland systems offer a suitable social economic alternative to the classic wastewater treatment plants. In order to study the treatment mechanisms occurring in the soil–plant system, we set up a small-scale pilot wastewater treatment plant composed by a
