CSRE - Model MD -Membrane Distillation System
CSRE MD is driven by a vapor partial pressure difference triggered by temperature difference across hydrophobic membrane which is a barrier for liquid phase, only allowing vapor phase to pass through membrane`s pores. CSRE MD, a revolutionary process to desalinate high salinity of waste water, is constructed by anti-corrosive plastic materials, operated at low OpEx and an alternative technology to current metalic evaporators.
Strong chemical tolerance
Strong resistance to acid, alkali and oxidants Concentrate acids & alkalis, e.g., sulfuric acid, hydrochloric acid, sodium hydroxide, and oxidants, e.g., ferric chloride, high chlorine reagents, without neutralization, even till crystallizes.
Low-temperature & multi-effect design
CSRE MD adopts mult-effect, heat-recirculating and modular design. CSRE MD is driven by low-temperature heat sources.
CSRE MD effectively utilizes low-grade waste heats and energy consumption can be lower than 2-5kWh/ t of water.
MD work flow diagram
Utilizing residue/waste heat in plant, according to different components in waste water, MD concentrates waste water to a concentration close to saturated state for maximizing volume reduction and reducing total volume of subsequent crystallization, leading to low OpEx of whole process.
