• Portable, light-weight and excellent for out-door applications, household filters and also disaster relief.
• Electricity free - purification process can be carried out by gravity-driven filtration or mechanically-enhanced filtration
• The composite structure of the membrane create excellent antifouling and anti-bacterial properties. (high rejection for heavy metal ions (e.g., Pb2+, Cd2+, Ni2+ and Cr6+) and high water permeability: remove unwanted particles (e.g. suspended inorganic particles and organic particles), biological entities (e.g. pathogen and bacteria), and heavy metal ions (e.g. Pb2+, Cd2+, Ni2+ and Cr6+).

•  
• Provide an inexpensive, scalable, and sustainable methods to produce and purify water
• Membrane filtration market for the preparation of pharmaceutical solutions as to remove viable and nonviable particles in order to clarify or sterilize the solution.
