<p>The RO plant has circulation pump (21) and electrochemical ozone generator (22) that are integrated into permeate return line (20). A valve (25) is integrated into recirculation line (24) and permeate-return line downstream of branch of recirculation line. A permeate return-line section (26) is branched off from permeate supply line (16) upstream of termination of recirculation line into permeate supply line. A pressure holding valve (27) is arranged in permeate return-line section, so that a partial permeate stream can flow back to the supply tank (3). An independent claim is included for a method for disinfecting lines of RO system.</p> |
