Ferric Chloride

Typical Applications:

• Potable water - turbidity reduction, colour elimination, enhanced coagulation, arsenic removal, filter reconditioning, and lead control. In 
• Waste water treatment - phosphate precipitation and removal, enhanced sedimentation, dewatering of sludge streams, and sulfide based odour control.

Special Considerations:

• Hazardous chemical and proper personal protective equipment should always be used when working with the chemical.

Metcon Product Recommendation
For safe, reliable, and accurate metering of Ferric Chloride, 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 Preparation and 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 

• Depending on the ferric application, Metcon can provide real time monitoring and controllers to optimize chemical addition. An example of this capability would be in the phosphorous removal process at a wastewater plant or lagoon. We can provide an online analyzer for continuous monitoring, a process controller for automatic addition rate adjustments, and a videographic recorder for traceability and data recording.
