Hydrogen Peroxide (H2O2)

Typical Applications:

• Oxidation and disinfection processes in water and waste water treatment
• Odour control

Special Considerations:

Metcon Product Recommendation
For safe, reliable, and accurate metering of Hydrogen Peroxide, Metcon recommends a complete liquid chemical feed system for storage and metering. 

1. Storage & Handling

• SAFE-Tank Cross link polyethylene storage tanks for storage requirements up to ~33,000 L. These tanks provide 110% containment for safe and a superior resistance with it's antioxidant resistance coating.
• If the chemical will be stored bulk and transferred to day tanks, cross link polyethylene tanks should be used. Metcon can provide transfer pumps and connection assemblies constructed of suitable materials for the chemical, as well as automatic transfer controllers based on tank level.
• To monitor inventory, an ultrasonic level transmitters and electronic scales are the preferred options.

2. Chemical Metering

• A factory engineered, assembled and tested liquid chemical metering system is provided with a choice of either metering pumps (diaphragm/peristaltic) or liquid eductors. The selected metering technology is mounted on wall mounted polyethylene panels or free standing skids (FRP/carbon steel/stainless steel).
• Systems are designed to meet plant requirements for redundancy.
• Metcon provides all of the appurtenances required for safe and accurate metering. This includes pressure relief / back pressure sustaining valves, pressure gauges, pulsation dampeners (when required), flow monitoring devices, calibration columns, isolation valves, and local control panels.

3. Controls & Instrumentation 

• The metering pump system has a local control panel that can allow local metering control (duty selection/automatic switchover), remote metering control from the plant, and feedback to the plants' monitoring system for chemical feed system status and alarming.
• Hydrogen peroxide residual can be monitored and adjusted with an amperometric probe style peroxide analyzer & controller.
• Metcon can also provide real time monitoring, process controllers for automatic addition rate adjustments, and a videographic recorder for traceability and data recording.
