fluid levels of the three tanks 202 203 204 to equalize and remains open during the cleaning cycle the oil and grease transferred to and trapped in the discharge chamber 204 resultant of the fluid reclaim cycle is re hydrolyzed into molecular suspension with the microbe rich emulsifier in the discharge chamber 204 this is accomplished by diverting part of the excess volume of solution generated by the pressure pump 226 during the cleaning cycle by way of a u201c t u201d 243 c in the primary pressure line 243 the diverted volume is controlled by a flow valve 245 which limits a specific amount of reclaimed washing fluid to be discharged by way of a fan spray nozzle not shown positioned over and directed at a downward angle into the surface of the oil and grease floating in the discharge chamber 204 to agitate the fluid above the perforated plate not shown when the fluid has been reclaimed a timer located in the bioremediation unit 200 located on the roof 1 is set to activate a short ten minute cleaning cycle during off or slow times when the system is energized 1 a normally closed contactor opens and disables the exhaust fan 8 to prohibit the fan from exhausting atomized cleaning solution into the atmosphere 2 a pressure pump 226 draws suction from one of three tanks in the bioremediation unit the circulation chamber 202 and pressurizes a low volume low pressure spray boom assembly 23 said assembly 23 is comprised of rotary nozzles 24 connected by pipe sections 23 b 23 g etc fig4 and mounted vertically inside an exhaust flue 2 and horizontally along the length of any existing conventional commercial or institutional kitchen exhaust hood 5 above and behind the baffle filter bank 601 a.
