  • Product Detail
  • Company Profile

    Liquid Filtration -- Using thin (~50 μm) micro-porous metal and ceramic membranes

        1. Solvent Filtration

    • Provide particulate-free solvent to equipment or process usage, such as, HPLC solvent elution, solvent cleaning system, etc.

    • Recovery of nano- and micro-sized catalysts, adsorbents, or products from reacted solvents

        2. Water Filtration

    • Remove micro-organisms, bacteria, viruses, and particulates from process water, tapwater, seawater in one pass.

        3. Performance Attributes

    • Stable in various organic solvents or oils

    • Stable at elevated temperatures

    • Biofouling resistance

    • High permeance or flux

    • Cleanable for re-usage

       4.  Membrane filter size: 

    Filter shape Disk cell    Rectangular cell       Large Module
    Membrane working area 3.0 cm2 40 cm2 Stack of 60 membrane sheets, up to 4 m2

     

       5.  Example 1. Filtration of Carbon Black N110 in 99% Isopropyl Alcohol (IPA) solution

    N110 particle size Membrane area Feed turbidity Permeate turbidity Filtration efficiency
    15-18 nm 40 cm2 18.28 NTU 0.00  > 90%


          Example 2. Filtration of cleaning solutions down to turbidity =0.00 for re-usage

    De-ionized water and 70 wt.% isopropanol/water in two respective cleaning baths at 50oC working temperature are reused after filtration, resulting substantial reduction to generation of waste solutions.

     

    Gas Filtration -- Using thin (~50μm) micro-porous metal and ceramic membranes

        1. Uniform pore size

               Nickel alloy membrane:    adjustable between 20 nm to 1 μm

              Coated-zirconia membrane with smaller pores than Nickel alloy membrane

        2. Performance Attributes

    • Filtration of particulates > 20 nm over a broad range of concentrations, particulate matters (inorganic, organic, micro-organism, viruses), and temperatures (cold, hot)

    • Applicable to various gases, air, oxygen, nitrogen, hydrogen, steam, oil vapor, or hydrocarbons

    • High permeance

    • Cleanable for repeated usage

        3. Example: Complete filtration of wood smoke (PM2.5 = 62,000 μm/m3)

    Molecule Works Inc. (MWI) is a US-based technology company, registered in the State of Washington, and established in 2015 to pursue commercialization of three fundamental inventions licensed from Pacific Northwest National Laboratory (PNNL): thin porous metal sheet, thin-sheet zeolite membrane, and cassette-type membrane module. Since then, MWI has successfully demonstrated scale-up of all the critical membrane preparation steps and established its proprietary pilot manufacturing capabilities for production of thin porous metal and zeolite membrane sheets. The pilot-scale manufacturing capabilities enable production of a large number of 20cm x 20cm membrane sheets for application prototype development and customer sampling.

    MWI has developed several innovative manufacturing methods and processes for production of the porous metal sheet-based membrane products at low cost. MWI has also made a series of new inventions for applications of its membrane products.
