Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this paper, the performance of a multistage vacuum membrane distillation (MSVMD) which is thermodynamically similar to a multi-stage flash distillation (MSF) is evaluated for desalination, brine con...

New developments in pressure- and thermally driven membrane desalination technologies offer the potential to cost-effectively treat high-salinity waters, especially when powered by low-cost solar electricity thermal energy. This paper presents a comparative techno-economic assessment of state-of-the-art most promising for high recovery desalination, namely, osmotically-assisted reverse osmosis ...

In general, the optimization problems contain more than one response, which often conflict with each other. This paper proposes the TOPSIS-based Taguchi optimization approach to determine the optimization of reverse osmosis process parameters for improving recovery and quality of permeate. The performance criteria are identified for Permeate are COD, Total Solids, Conductivity and Hardness in r...

Mining activities are notorious for their environmental impact, with acid mine drainage (AMD) being among the most significant issues. Specifically, AMD has recently been a topical issue of prime concern, primarily due to magnitude its environmental, ecotoxicological, and socioeconomic impacts. originates from both active abandoned mines (primarily gold coal) is encountered in Canada, China, Ru...
