Removing Iron and Manganese in less than 10 minutes
Routine cleaning is essential for a streaming current monitor to work properly. Therefore, plant operators desire a unit that is easy to clean, uses a good cleaning agent, and has a quick recovery of the streaming current reading after the cleaning is complete. A 1:1 solution of hydrogen peroxide (approx. 5%) and acetic acid (common household vinegar) offers plant operators a simple and safe alternative to harsh cleaners. A simple spray bottle and brush are all that is needed for a cleaning that takes less than 10 minutes to dissolve iron, manganese, and permanganate stains from the flow cell.
Remove probe, piston and flow cell from the SCM.
Spray these pieces with 1:1 solution and allow the solution to set for a couple of minutes.
Brush the probe and piston before reassembling.
After reassembly, start process flow to rinse the unit and establish a correct reading.
