Chemical Dosage For Manganese Greensand

Date : 5/19/2014
From : LISA

Question

I HAVE A 2 CUBE 5600 HEAD GREEN SAND FILTER AND WAS WONDERING HOW MUCH POTASSIUM DO I USE WITH A 12 GALLON FLOWRATE?

Answer

The regeneration level is 1 - 4 oz. of KMnO4 per cubic foot of greensand. A gallon of water will dissolve 2 – 4 ounces of potassium permanganate dependent on the temperature of the water.

Optimum regeneration time is 30 minutes. Rinse volume is 40 -50 gal./cu-ft. or until all traces of potassium are gone.
