SELECTION & SIZING

• Several factors affecting life and efficiency are:
  • particulate load in fluid
  • type & amount of contaminant to be adsorbed
  • flow rate, temperature & pH of fluid
  • single pass or recirculation system
  • contact time with wash
  • steady or intermittent use
• Activated carbon is used to purify, deodorize and upgrade quality of liquids. Early in the system it removes contaminants or it is used as a final step to improve product quality. Activated carbon prefers chemicals with low solubility, low polarity and a low degree of ionization.
• Single pass applications should employ molded activated powder, impregnated carbon or paper impregnated activated powder carbon cartridges. Recirculating systems should employ granular carbon cartridges.
• Series filtration utilizing a string wound particulate filter upstream of the carbon cartridge will increase the carbon cartridge life immensely.
• Sizing based on contact time. Longer contact time results in higher absorption.
• Higher than recommended flow rates can be employed, but removal efficiency may be sacrificed. The lower the GPM flow rate the greater the efficiency of the carbon cartridge. We recommend a maximum of 2 1/2 gpm per 10" cartridge length.
