It ability to harvest carbon as a resource by separation of grit and organic material. Organics are sent to the treatment process downstream (1lb organics produces 16ft3 biogas). Collecting and washing the sand/grit will reduce the wear and tear of downstream equipment by reducing grit build-up in tanks and digesters. Optimal operation of an aerated grit chamber can reduce the energy up to 75% energy in order to retain as much grit as possible. The last added benefit to the ST JERNHOLM system is that it is a closed system and minimal organics in output reducing the odor produced equalling in happier neighbors and a better working environment and reduced risks for the operators.
