In-situ cleaning of the bilgewater processing plates of stacks within the tank chamber of an oil/water separator is performed by an injected chemical cleaning agent while being dispersed by diverted flow of pressurized air introduced into the tank chamber below the plate stacks in the form of air bubbles emerging from plural branches of an air sparging array positioned in underlying alignment with crest formations of the processing plates.

A storage chamber within a paint dispensing reservoir tank is maintained led with paint from a refill paint source during recirculation of such paint through a paint cleansing filter within the chamber for supply of filter cleansed paint to a paint dispensing outlet under control of a metering system involving use of a valve controlled air-powered pump and flow metering regulating cylinders.

A pulper includes a pulping chamber, a pulping mechanism, and a non-pulpas collection chamber attached to a bottom of the pulping chamber below a top of the pulping mechanism in an annular area outside of the pulping mechanism. The collection chamber includes a container with openings at first and second ends; a basket having an opening at a first end and disposed inside the container wherein at least a bottom portion of the basket includes perforations; a pipe connection located at the second end of the container; means for removing the basket from the container; and means for preventing material from entering a space between the basket and the container; wherein the first end of the container is inserted into the pulping chamber. The collection chamber does not interfere with the fluid flow around the pulping mechanism and can collect a relatively large amount of non-pulpables without requiring pulper shutdown.

A solid waste pulper including a pulping chamber, oriented at an angle, hng a first inlet port for introducing solid waste material to be pulped, and a second inlet port in the pulping chamber for introducing water into the chamber. A blade assembly, preferably formed of a plurality of rotatable blades and a plurality of fixed blades, is mounted in the chamber for pulping the solid waste material introduced in the chamber, the water mixing with the pulped waste material to form a slurry. A sizing ring is provided in the pulping chamber through which the slurry must pass to be discharged, the sizing ring having a predetermined area for limiting the size of the pulped waste material in the slurry which can be discharged from the pulping chamber. The pulper also includes a discharge port coupled to the pulping chamber for discharging the slurry containing the pulped waste material, the discharge port having a predetermined cross-sectional area which is smaller than the area of the sizing ring, thus limiting the maximum flow of slurry discharged from the pulping chamber.
