Cleaning 4040 Membranes
Really trying to do this right so I don’t mess up my new membranes.
A few questions....clean membranes running neutral water (distilled or permeate) should have a PH of 6-7 approximately. When running sap, how do you determine your membranes are dirty and need a soap wash as opposed to just a rinse?
Spoke to Clayton at MES. He said I should mix my soap to a PH of 11. Run it through the membranes and keep an eye on it as it may drop. I did that yesterday and then ran about 75 gallons of permeate through the membranes to rinse the soap out. Got them back to a neutral PH of 7.
Is that how everyone does their rinses, cleaning, and tests?
Thanks!
