Tray Fouling, Cleaning and Prevention What are the typical problems encountered with the system O&M for sliding tray strippers? If you are using an extraction well that is being injected with hydrogen peroxide and iron sulfate can that cause problems with the materials of the E-Z Tray Air Stripper beyond iron fouling? At what levels of calcium, magnesium and iron would you recommend pre-treatment to prevent scaling? What is the highest concentration of dissolved iron that you can have in successful tray stripper applications? In a drinking water system with 27 grains of hardness, and adding a phosphate, how will this affect the trace? How do you remove iron/hardness scaling/fouling? Can fouling not occur within the tray holes? How easy is it to pull trays?
