PLANT AND PROCEDURE FOR THE RECOVERY OF POLYVINYL ALCOHOL FROM THE WASHING BATH IN THE TEXTILE INDUSTRY

摘要

The present invention relates to a plant and procedure for the recovery of Polyvinyl Alcohol (PVA) from the washing bath in the textile industry. The system is of the type that comprises a plurality of stations, of which the first station (2) comprises a screening and accumulation section, the second station (3) comprises a filtering section that generates on one side a flow of clean water (permeate) which is sent to a an insulated tank (26) and on the other side a flow (concentrate) that is sent to a third station (4) which comprises a PVA gelification section, where the PVA passes from a liquid to a solid state by lowering the temperature.
