Bi-On S

The new filtering media Bi-On S is the alternative to activated carbon (AC), normally used in solvent recycling systems.

Bi-On S is specially effective in facilities dedicated to the recuperation of solvents such as ethyl acetate and ethanol. These solvents are commonly used in graphic and printing industry (tampography, flexography, etc).

Its main advantages are:

- Activated Carbon (AC) catalyses the oxidation of Volatile Organic Compounds listed as peroxides. Those start in turn a chain reaction which causes an increase in the bed temperature, which sometimes can be above the ignition temperature of AC. In these circumstances there can be a fire in the filtering bed.
- Auto-ignition is problematic as it usually
- Occurs unexpectedly,
-May damage falilities.
-May set free toxic substances which pose a considerable threat to people and the environment.
- Natural zeolytes which compose the filtering media Bi-On S do not have self-ignition point, whereas AC has a value of 420-450 ºC approximately.
- Bi-On S eliminates the fire hazard which present the facilities dedicated to the recovery of solvents such as ethyl acetate and ethanol.
- Bi-On S does not generate the annoying and dirty dust generated by activated carbon (AC). Unlike CA, Bi-On S pellet makes handling easy during the filling of filtering towers in the solvent recuperation units.
