Oxidant Tank Lid
The oxidant tank lid should cover the tank during operation, which helps reduce volatilization and
extends the life of the oxidant solution.
Feed Line Connection/Injection System
The oxidant tank outlet valve is located at the bottom of the oxidant tank. This oxidant tank outlet
provides oxidant solution to the water system for disinfection purposes. Oxidant solution can be injected
into the water system with a chemical feed pump, or a venturi injector that is typically mounted in a
side-stream of the main water line. The injection system should be designed by a qualified engineer,
MIOX distributor, or salesperson.
Note: Refer to Injection System Manufacturer’s Manual for installation
guidelines.
Overflow Port
An overflow port connection fitting is provided at the top of the oxidant tank. This should be piped to a
drain or other suitable discharge outlet with 1” schedule 80 CPVC pipe. For sites with two oxidant tanks
installed, the overflow ports should be piped to each other with a common drain. If the customer elects
not to run the overflow drain, then the outlet must be plugged to prevent gasses in the storage tank
from venting to the room.
Do not plumb brine and oxidant tank overflows into the same drain header as the water
softener discharge. Install separate drain headers to a common floor drain. If all
systems are tied into the same drain header, high back-pressure from the water softener discharge
drain can backflow up the brine and oxidant tank overflow lines and contaminate the brine generator
and oxidant tank with softener wastewater. This will result in brine tank flooding, calcium carbonate
contamination of the electrolytic cell, and dilution of the oxidant
If a dilution air system is used, the overflow port must be equipped with an internal drop
tube to prevent the forced air leaving the tank through the overflow port
