ABSTRACT:
A system of three tanks and associated fluid communication lines and valves added to a conventional septage pumper/hauler truck to carry a supply of lime slurry and inject it into the septage hauling tank 1 in measured doses. Air vacuum or pressure is used for moving the fluids between tanks without fluid pumps. The three tanks of the invention include a lime slurry carrying tank 3, a lime slurry dosing tank 7, and a water tank 5 for flushing the system. Compressed air 37 is applied to each of these tanks as needed to push the fluid contents through the connecting pipes. An air vacuum that is normally provided to the main tank 1 for loading septage is also employed in the invention to load tank 3 with lime slurry. By manipulating the valves in an appropriate sequence, the dosing tank is filled from the lime slurry carrying tank, then the slurry in the dosing tank is injected into the septage carrying tank simultaneously with septage for mixing. The ph of the septage is then tested, and the dosage repeated if necessary until the required level is achieved. At the end of the day, the valves are manipulated in another sequence to flush lime slurry from the tanks and pipes with water.
