With a large California dairy located one mile away from an ethanol production facility, a local developer saw an opportunity to offset fossil energy usage through the use of biogas produced from the manure. The digester produces 325 cfm of biogas with H2S concentrations of 1,000 ppm.
MV Technologies provided a single-vessel H2SPlus System, designed to reduce the H2S concentrations to below 100 ppm over the course of the approximately 255 day media bed life.

This agricultural digester facility, which produces 270 SCFM, utilized the activated carbon vessels (right side of photograph) for a period of 6-months to remove 2,000 ppm, accumulating more than $150,000 in operating costs for H2S removal alone.
MV Technologies provided a solution to replace an activated carbon system integrated with a CHP installation. A single-vessel system was integrated, utilizing 12’ diameter x 14’ tall vessel containing 1,344 ft3 of MV’s media. The system is designed to have a 270 day bed life with an approximate annual media expense of $35,000.
