ICM/Phoenix provided a pre-fabricated Anaerobic Bio-Methanation system at ALI in San Juan.  The system was designed and skid-mounted at the ICM, Inc. fabrication shop in Colwich, KS, then shipped as a complete unit to San Juan for piping and 480v electrical hook-up.  

     The system was designed for 700 pounds per day of Chemical Oxygen Demand removal, therefore, it could be skid-mounted as a package treatment unit.  Tankage is polyethylene and piping PVC and polyethylene, while system pumps are stainless steel centrifugal.  The system fit the plants' limited waste water treatment budget and has been on line and operating satisfactorily since 1996.  

     Routine COD reduction is well in excess of 90%, which keeps the plant within compliance limits of the Puerto Rico Aqueduct and Sewer Authority (PRASA).  COD loading has varied to as high as 1,500 pounds per day without significant plant upset.  The plant requires less than one hour per day of operator attention.  

     Phoenix Bio-Systems personnel provided all training and start-up services along with operations and maintenance manuals.
