NOTES
1. A booster is strongly recommended to improve the reduction of
TDS. Higher pressures will help maintain the membrane’s maximum
rejection performance.
2. The reverse osmosis membrane used in these systems may be
damaged by chlorine. These systems include activated carbon filters
which protect the membranes by reducing chlorine. Influent chlorine
should not exceed 3 mg/L.
3. A softener is strongly recommended for water over 10 gpg hard.
Installing a system without a softener on water with hardness higher
than 10 gpg will reduce the life of the membrane.
4. Additional information on factors that affect RO performance can be
found in the “Performance & Technical Information” section.
