ABSTRACT:
A jet pump macerator pump sewage handling system which provides a unique waste control system for use in mobile units such as passenger trains and ships in which multiple toilets are connected to a transfer manifold pipe which communicates with a non-clogging jet pump which is formed with a venturi and through which liquid material is driven by a macerator pump. Waste material from the toilets is drawn by the jet pump through the transfer manifold pipe and discharged into the retention tank. The macerator pump withdraws material from the retention tank, grinds it and discharges it back into the retention tank. The macerator pump has a self-cleaning feature in that it reverses and cleans itself whenever a loss in discharge pressure due to excessive solids loading is sensed. The transfer manifold pipe is virtually free from clogging due to the action of an air induction valve which keeps waste material in the manifold pipe moving without allowing it to accumulate.
