Membrane distillation (MD) is a desalination technology for recovery of water from high-salinity solutions. It is a new technology that combines distillation and membrane separation and the transport of vapor through the membrane pores is driven thermally. In many industries, the ion-exchange resins are used and have different applications such as making soft water, increasing the clarity of solutions and bleaching. Water is usually used to regenerate these resins and the effluent of regeneration usually has a notable level of salinity. In this paper, the characteristics and capabilities of membrane distillation as a method to treat high-salinity effluents are studied focusing on the effluent produced from the regeneration of ion-exchange resins in glucose industry. Ion-exchange resins are highly used in glucose factory and have different applications from soft water producing to bleaching and clearing glucose syrup.
