Water purification of arsenic- contaminated drinking water via air gap membrane distillation (AGMD)
Arsenic contamination in shallow tubewell water is a serious health issue in Bangladesh and other Southeast Asian countries. Rural and remote areas in these locations continue to face tremendous challenges in providing access to affordable and safe arsenic-free drinking water. In recent years, intensive efforts have been undertaken to identify appropriate technologies for arsenic removal. This ...
متن کاملApplication of powdered activated carbon (PAC) for membrane fouling control in a pilot-scale MBR system.
Membrane fouling is considered to be the most serious drawback in wastewater treatment when using membrane bioreactors (MBRs), leading to membrane permeability decrease and efficiency deterioration. This work aims to develop an integrated methodology for membrane fouling control, using powdered activated carbon (PAC), which will enhance the adsorption of soluble microbial products (SMP) and imp...
متن کاملEffect of Module Inclination Angle on Air Gap Membrane Distillation
Air gap membrane distillation (AGMD) experiments were performed with varied temperature and varied module inclination angles to characterize the effect of module angle on permeate production and thermal performance. While AGMD is potentially one of the most energy efficient membrane distillation configurations, transport resistances in the air gap typically dominate the thermal performance, res...
متن کاملperformance of a powdered activated carbon (pac) augmented activated sludge process treating semi-aerobic leachate
semi-aerobic leachate is characterized by organic matter (cod, bod) which is relatively low in concentration and difficult to biodegrade. in conventional treatment systems, the low biodegradability is attributed to partial stabilization of leachate at the landfill. biological treatment of leachate in malaysia is not well established and any important data for the treatment process is not availa...
متن کاملEffect of Powdered Activated Carbon to Reduce Fouling in Membrane Bioreactors: A Sustainable Solution. Case Study
Membrane Bio Reactors (MBRs) are mainly used for industrial wastewaters applications where their costs can be more easily afforded. High costs are basically due to energy consumption and membrane cleaning or replacement. Membrane fouling is responsible for reducing treated water production and increasing maintenance as well as operation costs. According to previous researches, the addition of P...
