Getting the most out of your JJM
®
Neutralizer
Acidic wastewater neutralizers like all filtering devices need both maintenance and replacing. The average pH level of acidic waste-
water produced by today’s condensing boilers, hot water heaters, furnaces, flue stack drains, and stack economizers is 3.2pH. When
using a passive Inline Tube, Tank, or Canister the range of pH modification will fall in between 5.0 and 9.5 pH.
When the pH falls below 5.0 at the outlet port of any neutralizer the active ingredient must be replaced. Media replacement schedule
will depend on several factors including Operating Hours, Efficiency, System Design, and Neutralizer Piping Scheme. The active
ingredient in the case of JJM® products is Magnesium Hydroxide Pellets. The trade name is pH Power Pellets®.
Before changing the pellets when the pH level falls below 5.0 you can get the most out of your neutralizer by first agitating the pellets.
In the case of an inline tube products try lightly tapping the outer sides of the tube with a rubber mallet several times and then check
the pH level once again at the outlet port. You may find that your pH level has risen back into the 5.0 to 9.5pH range.
When your neutralizer is a tank product with loose pellets you can simply use a wooded dowel to stir the pellets and again use
fresh tap water to flush out the tank.
If your neutralizer pellets are incased in a porous pellet bag there are three methods to agitating the pellets:
1. Remove the pellet bag or bags from the tank and using your hands move the pellets around inside the bags.
2. Using a five gallon bucket filled with fresh tap water, use step one with the bag under water.
3. Using a fresh water hose slowly pour fresh water over both sides of the pellet bag and also use method one.
If the pH level is has not risen back into the safe range of 5.0 to 9.5 pH the pellets must be replaced.
If you have our Model V-250 or V-250 Combi vertical canisters try the following method:
1. Twist off the outer canister to get access to the inner pellet cartridge and over a five gallon pail shake the Cartridge several times
to agitate the pellets.
2. Again using a five gallon pail filled with fresh tap water let the cartridge soak for five minutes under water and then drain and hand
shake the cartridge to agitate the pellets. Also clean out any sediment which may be held within the outer canister.
DURING ALL OF THE ABOVE PROCEDURES THE FOLLOWING SAFETY ITEMS MUST BE USED:
1. WEAR SAFETY GLASSES
2. WEAR RUBBER OR LATEX PROTECTIVE GLOVES
3. SHUT OFF ALL ELECTRICAL POWER TO THE HEATING UNIT OR UNITS BEFORE SERVICING YOUR
NEUTRALIZERS.
The pellets are Non-Hazardous and can be disposed of in your normal refuge.
