BD_Zorb

Biodiesel Purification Media

BD-Zorb is a hybrid absorbent and cation exchange media formulated to purify (dry-wash) biodiesel. It removes salts, soap, water, and glycerin. It is commonly utilized as a "first step" purification in a two-part process of purifying biodiesel. Our DudaLite Ion-Exchange resin, also known as DW-R10, is used as the "second step" in the process. BD-Zorb has a high capacity for soap. Consequently, it will extend the life of the DudaLite DW-R10. It is important to remove as much methanol as possible prior to processing with BD-Zorb.

Application Guidelines

How much biodiesel will one pound of BD-Zorb treat?	One pound of BD-Zorb will treat 70 to 100 gallons of biodiesel. (based on an average of 1500 ppm of hydrophilic contaminants) Results will vary based on level of impurities and flow rates.
How many pounds of BD-Zorb are required?	One pound of BD-Zorb is required for every gallon per hour of biodiesel flow.
How do I size/design exchange vessels?	Use a minimum bed depth of 48 inches and a maximum 72 inches. The diameter should be based on the desired throughput per hour with consideration of the rate of one pound of BD-Zorb per gallon of biodiesel flow.
How do I know when my BD-Zorb is exhausted?	Monitor soap levels, pressure drop and turbidity.
What are the safety considerations?	First, you must read the MSDS before handling the product. Remember to protect yourself from wood dust. Dust can explosive with an ignition source. The spent media cannot be composted.
