The MIOX Advantage
Low 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.
