US Patent:

6810365, Oct 26, 2004

Filed:

Jun 13, 2002

Appl. No.:

10/171574

Inventors:

Stuart H. Brown - Severna Park MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

B01D 2132

US Classification:

702188, 210 93, 210 97

Abstract:

The integrity of membranes utilized on-board marine vessels to separate oil from oily waste water is monitored by conducting the cleansed waste water along a predetermined path through an enclosure within which a surface of such waste water during flow is exposed to a confined body of air so as to effect the extent of light absorbed therefrom into the waste water. Sensing the light remaining in the body of air produces signals from which membrane integrity may be determined based on the presence of an oil film on the air exposed waste water surface.

International Classification:

B02C 2308

US Classification:

241 69

Abstract:

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.

Appl. No.:

9/413777

Inventors:

Stuart H. Brown - Severna Park MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

B01D37/00;35/02

US Classification:

210769

Abstract:

Liquid waste generated aboard a maritime vessel is separated into oily and non-oily components for separate treatment to obtain flow streams having different waste contents. Those of the flow streams having waste content reduced by the treatment are discharged overboard while the other flow streams having concentrated waste content are subject to incineration.

International Classification:

B02C 1840

US Classification:

241 21

Abstract:

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.
