Notes

1. The recommended design range is for operational and design conditions under low fouling and scaling. Operating the SU-series element outside this range may reduce effective membrane life.
2. Feed and brine water must meet the specified pH range.
3. Cleaning and sterilization should follow the recommendations in the technical bulletins for SU-series elements.
