5.2.5 Regenerant Use Table - Potassium Permanganate (KMnO4)
Notes:
1. Chemical dosage recommendations typify
requirements for single batch regenerations.
2. When combining batch regeneration with continual
feed of either chlorine or potassium permanganate,
reduce recommended chemical dosages above by
50%.
3. Table above reflects a 4 oz./cu. ft. of media,
regenerant dosage, dissolved in 1 gallon of
water/cu. ft. of media. Dosage rates will vary with
various media manufacturers’ recommendations.
Check manufacturers’ specifications for dosage
recommendations.
