[S]ulfur [Fe]rret

[S]ulfur [Fe]rret is a cost effective process for removing Hydrogen Sulfide from Biogas streams.  It is a cost effective iron chelate regenerable process for iron Hydrogen Sulfide removal.  It has a number of significant advantages over other options in the industry:

1. A cost effective regenerable process that relies on iron-chelate chemistry
2. Does not rely on unstable bacteria colonies that take time to develop and can die off if conditions are not ideal
3. Low biogas backpressure (<10"wc)
4. Can operate at a wide variety of pressures (vacuum to 100 psig)
5. Very reliable with minimal downtime
6. The only waste product is sulfur cake which has value as a feedstock for numerous industries
