The system operates on the principle of simple thermodynamics (heat and mass transfer) and the driving force is the partial vapour pressure gradient across the membrane. The TS-30 system operates at relatively low temperatures and pressure when compared with the conventional thermal and pressure driven membrane process and handling high salinity wastewater.

The benefits of the technology have been well demonstrated for industrial liquid-waste treatment and resource recovery for pharmaceutical, chemical/pulp and metal finishing/mining industries. It helps to close the industrial liquid-waste loop and recover up to 100% chemicals (metal salts, acids and other chemical compounds) and >95% of water at >80% lower operating cost compared to traditional evaporators.  In addition, the technology also reduces the carbon footprint by up to 80%. 

Dr J Antony Prince, CEO of Memsift Innovations, said: “The patent further strengthens our commercialization efforts and differentiates our TS-30 Improved Membrane Distillation system from traditional membrane distillation methods.”
