Remove Alconox from rinse water

Q.  How do you remove Alconox from rinse water prior to discharge to the sewer? Will reverse osmosis work effectively in the removal of the Alconox from rinse waters?

A. Alconox is a blend of organic surfactants and inorganic sodium salts of carbonates and phosphates.  In principle, reverse osmosis will remove Alconox from rinse water as long as you are using a sufficiently small molecular weight cut off to remove sodium carbonate.  Although reverse osmosis would probably work, it might not be the most cost effective approach.  Depending on why Alconox needs to be removed and if all of the components of Alconox need to be removed, there might be less expensive separation techniques that would work.
