    Membrane filtering

    Invented in France at the end of the 1960s, membrane filtering of milk has become generalised in dairies and cheese-making. It meets current constraints, i.e.:


    • Product quality
    • Innovation
    • Production control
    • Reduction of material losses
    • Increased output
    • Reduced effluent released into the environment
    • Lower energy consumption.



    The principle behind membrane filtering is to separate the different components of a liquid using a porous membrane. The product flows at a tangent to the membrane and filtering occurs through pressure difference. The membrane pore size will depend on the required application. From the largest to the smallest we refer to microfiltering, ultrafiltering, nanofiltering and reverse osmosis. Depending on the selected application, the membranes can be ceramic (mineral) or plastic (organic).



    Tecnal offers several turnkey membrane filtering solutions for microfiltering, ultrafiltering, nanofiltering and reverse osmosis.



    We can also propose the hire of a multi-technology pilot with, if you wish, support from our filtering and cheese-making technology experts.




    • Brine clarification



    • Milk concentration to standardise proteins
    • Precheese production (un-drained cheese)
    • Whey concentration and denaturing before reinclusion in the cheese
    • Production of WPC, WPI, MPC or MPI
    • Concentration of fermented milk for fresh cheese without separation


    Reverse osmosis:

    • Milk concentration to standardise dry extract
    • Milk or whey concentration before drying or shipment
    • Dairy effluent processing (cow waters, white water, etc.)
