Design Considerations

In order to accurately size a reverse osmosis system for commercial or industrial applications, we will need to know the following:

  • The amount of water you expect to use per 24-hour period.
  • Your peak water demand.
  • Operating hours per day.
  • Your water pressure.
  • The quality of your water – see our water analysis section for more information.
  • What you plan to use the purified water for.
  • Your site layout.


Your local approved CWC distributor can help you calculate your purified water needs, and can arrange for a professional water analysis to be taken. For more information about CWC’s reverse osmosis systems and how the RO process can help you in your home or business, contact CWC today.
