[USCC] Using Wastewater Digesters for food waste diversion

[Nelson Widell]

I was intrigued by the concept of using existing wastewater digesters for anaerobically digesting food wastes.While there may be a number of equipment conversion issues, if the tankage is available,it would seem like something worthwhile pusuing.
  However, Mr. Andrew Niv's input confused me.He seems to be saying that using an existing WWTP digester would be uneconomical  vs. purchasing the Masstech(TM) process. The web site he refers us to indicates that the Mastech(TM) processor has a capacity of 100kg. per day. So the theoretical 500 TPD of food waste he uses in his example would require 5000 of his units. It is hard for me to envision how that is more economical than using pre-existing, paid for anaerobic digesters at a wastewater treatment facility.I'd like to hear more from Mr. Niv regarding mass balance,moisture and cost comparisons.
