An offshore sewage treatment facility or sludge facility is serviced on a ship. The ship is secured and in position by means of a single point mooring system which is attached to the vessel's stem or stern and is connected to a submerged pipeline as a conduit from the shore. This offshore facility is alternatively housed aboard a conventional offshore platform. The facility is totally and/or partially energy self sufficient by means of utilizing methane gas generated by the processing plant. The processing facility allows for primary and secondary waste water treatment and digestion, dehydration of sludge or solids, generation of methane gas, drying of sludge or solids and pelletization of sludge with end products or by-products of recyclable water for industrial and/or agricultural purposes, fertilizer after the dry sludge is mixed with potash, or the dry sludge may be manufactured into blocks suitable for the construction of buildings.

DETAILED DESCRIPTION What is claimed is: 1.
A substantially stationary and substantially permanently positioned self-contained off-shore sewage processing facility constructed and arranged for converting organic waste to disposable products so as to satisfy waste disposal needs of a community of in excess of 100,000 people and which is substantially supported by a vessel or platform.
2.
A sewage processing facility according to claim 1 which floats on water and is capable of being moved to a substantially permanent location.
3.
A sewage processing facility according to claim 2 which is in the form of a ship or barge.
4.
A sewage processing facility according to claim 3 in combination with and moored to a dock or a single point mooring system.
5.
A sewage processing facility according to claim 1 in combination with a substantially permanently positioned platform on which it is supported.
6.
A sewage processing facility according to claim 5 in which the platform is supported by concrete columns 7.
A sewage processing facility according to claim 1 in combination with subsea conduit means for conveying sewage from the community to the facility.
8.
A sewage processing facility according to claim 1 which is capable of processing more than 100 million gallons per day of raw sewage.
9.
A sewage processing facility according to claim 1 which comprises (a) a power plant capable of satisfying all energy needs of the facility and producing heat and (b) sludge drying means which produce odoriferous gases; and wherein the sludge drying means comprises heat from the power plant.
10.
A sewage processing facility according to claim 9 wherein the power plant is one which, burns fuel admixed with air, and the air includes the odoriferous gases.
11.
A sewage processing facility according to claim 10 wherein the odoriferous gases and air are in combination with exhaust heat from the sludge drying means.
12.
A sewage processing facility according to claim 1 wherein the disposable products comprise industrial quality water
