▎ 摘　　要

NOVELTY - The membrane distillation (MD) system comprises a MD module that includes membranes. The sweep gas inlet is operable to receive sweep gas and permeate outlet. The external heating element is positioned and operated to heat feed media to first temperature prior to introduction of feed media into MD module. The knockout chamber (200) is operated to receive mixture of unit of sweep gas exiting the feed media exiting feed outlet of MD module. The membrane is made of a material from the group consisting of hydrophobic polytetrafluoroethylene, hydrophobic polypropylene, hydrophobic polyvinylidene difluoride, hydrophobic polytetrafluoroethylene modified with carbon nanomaterials, carbon nanotubes, graphene oxide, hydrophobic polypropylene modified with carbon nanomaterials, and hydrophobic polyvinylidene difluoride modified with carbon nanomaterials. USE - MD system for sweep gas membrane distillation with integrated air stripping system used for desalination and wastewater treatment in industries, such as power plants, petrochemical, refining, manufacturing, paper making, textile dyes, removal of ions from radioactive wastewater, fruit juice concentration, and membrane crystallization. ADVANTAGE - The system provides high water recovery from the feed in water desalination or high concentration factor of the feed wastewater in zero liquid discharge (ZLD) application. It increases the yield of pure water, reduces the temperature and concentration polarization and membrane fouling, and provides higher degree of evaporation rate at the knockout chamber. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. A method that involves condensing the sweep gas containing vaporized feed media exiting each MD module. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the MD system. Knockout chamber (200) Heating unit (301) First separation unit (400) Air pump (401) Needle valve (402)
