Maintenance
MIOX system maintenance is simple, and safe.

Maintenance
MIOX on-site chlorine generation systems are about as easy to maintain as chlorine gas systems, but without the hazards. The primary maintenance requirements are as follows:
- Reload dry salt into the brine generator. For systems using bagged salt, this can take anywhere from five minutes up to several hours per week, depending on the size of the MIOX unit. For larger systems with a bulk brine generator, salt requires no handling at all; it is blown pneumatically into the generator by the delivery vehicle.
- Clean cell, if necessary. Depending on the quality of the salt, the cell may need periodic acid-washing to eliminate build-up of calcium carbonate. This can be done in-house without any special equipment. Sites using better quality salt often can delay acid washing their cells for extended periods of time.
- Change brine and water filters when required.
- Regularly check flows and chlorine production to verify system operations.
Maintenance tasks are done with standard hand tools, and most replacement parts are “plug and play.” Changing the electrolytic cell takes less than 15 minutes and does not require any special training. The equipment also integrates with existing controls and alarms and can be interfaced into SCADA systems.
Because the chlorine solution generated is less than 1 percent (< 10,000 mg/L) of free available chlorine (FAC), there is virtually no off-gassing, unlike with concentrated hypochlorite. The dilute concentration of the MIOX solution decreases corrosion to electrical conduit and wiring, to plumbing, and to facility ceilings and walls, even when dosed at the higher levels common in food processing plants. In addition, degredation is a non-issue, unlike with bulk bleach, since the solution is generated on demand and typically used within a 24-hour period.
The solution is generated at a pH of 9, making it 1,000 to 10,000 times less caustic than bulk bleach and about 100,000 times less acidic than chlorine gas. Operators can often drastically reduce the addition of acid or caustic to the treated water.
