Abstract
The present invention is directed to a polymer feed system and a method of using the same wherein clogging of the polymer input line is avoided by the use of air to purge the system of any unwanted polymer or electrolyte. The purging avoids the contact of the water with the polymer and the build-up of unwanted activated polymer and clogging in the supply and in the subsequent conduits.
