Chemical Feeding and Control
- Always flush the system with RO permeate before commencing a CIP. The cleaning solution should be prepared using RO permeate that is free of residual chlorine or other oxidising agents.Â
- Use a 2 % solution by weight. Adjust the pH in the range 11.8 – 12.2. Send the first 20% of the solution to drain to displace residual water in the system, and then begin circulation.
- Cleaning efficacy can be further improved by heating the cleaning solution and alternately circulating the solution for 30 -60 minutes and then soaking the membranes for 30 – 60 minutes.Â
- Your Membrane Works representative will assist with procedures and instructions, as needed.
