Solar Seawater Distillation by Flexible and Fully Passive Multistage Membrane Distillation

چکیده
Solar-assisted distillation is considered promising to solve the freshwater supply for off-grid communities. In this work, a passive and flexible multistage membrane (F-MSMD) device devised produce via solar with latent heat of vapor condensation being recycled enhance its energy efficiency. By designing siphon effect, source water continuously wicked into evaporation layer concentrated brine flows out before reaching saturation, which successfully solves otherwise challenge salt accumulation inside device. To achieve such flow, paper prepared from spent copy used as efficient delivery owing large pore size high hydrophilicity. An eight-stage F-MSMD exhibits stable clean production rate at 3.61 kg m–2 h–1 in newly designed siphon-flow mode. This work provides green route solar-assisted

Multistage vacuum membrane distillation (MSVMD) systems for high salinity applications
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...
متن کاملWater Desalination by Membrane Distillation
Water is the most common substance in the world, however, 97% is seawater and only 3% is fresh water. The availability of water for human consumption is decreasing due to increasing the environmental pollution. According to the World Health Organisation (WHO), about 2.4 billion people do not have access to basic sanitation facilities, and more than one billion people do not have access to safe ...
