    Default Membrane soap

    I have two MES 4x40 membranes that I purchased this year for the upcoming season. MES is out of RO soap. What to do?

    just use another brand from a maple supplier. Doesn't need to be their brand... Just be sure to stay within MES PH recommendations for their membrane.

    Another brand should work. Ask MES for a recommendation. Note that some RO soaps are buffered, so you can't use too much and stray outside the pH range of the membrane. Others are NOT buffered, so exceeding the range is possible.

    MES responded to my email and said they had received a shipment of soap so it's being sent today. Thanks for the replies. Good information to store for later use if needed.
