Abstract

Because of the high cost & nuisance factor of building new sewage plants it is proposed that concrete or stool decomposition tanks be placed off shore at the end of sewage outfalls. These structures to be built or scuttled on to the sea-bed in much the same way as the mulberry harbour used in the 1945 "D" Day landings of the last war. To increase the speed of decomposition in the sewage slurry it is proposed to lay air/oxygen bleed pipes 2, which bubble air/oxygen into the sewage slurry. Clarified water would rise to the surface & be syphoned into further aerated clarification tanks or discharged into the sea. <IMAGE>

Description

MARINE SEWAGE STATION There is a vital demand for sewage treatment around the coast where the effects of polution are increasing to an unnacceptable degree. Local Authorities are not treating this problem with any degree of urgency and because of the cost factor will not do so until forced to do so by law or pressure of local opinion.
Considering the cost problem large tracts of land are needed.
Expensive equipment or decomposition tanks are needed.
Objections to any new structures are fierce because of the smells.
It is proposed that large decomposition tanks be built 5-10 miles off shore fed by steel or plastic piping (to carry raw sewage).
The decomposition of raw sewage is created by beneficial bacteria destroying harmful bacteria. This can be accelerated and promoted by adding air or oxygen to the slurry.
It is proposed that oxygen or air be added to the decomposition tank by one or all of several methods.
Compressed air or oxygen pumped from compressors on land or on the structure into small bleed pipes.
Electrolysis of the water in the D-tank creating oxygen and hydrogen on the anodes and cathodes.
Large pistons operated by wave motion pumping compressed air into the aerate pipes. Liquid air or oxygen delivered by boat or insulated pipework to the D-tanks.
It is proposed that the D-tanks be constructed of steel or re-inforced concrete built in sections. Floated to a flat level sea-bed in about 40'-50 of water.
The prefabricated units would be assembled to-gether & BR< scuttled onto the sea floor. In much the same way as the mulberry harbour used in 1945. For the "D" Day landings.
On competion of assembly slurry & air/oxygen would be pumped in & the salt water in the tank displaced.
As the process of purification begins the clean water would rise to the surface & can be discharged into the sea.
Greater efficiency might be obtained by constructing a series of inner tanks all aerated & each syphoning into the next tank, the effluent beccoming progessively cleaner.
There would be a build-up of sludge in the D tank over a period of time. This could be sucked up into a tanker & BR< dumped in deep water.

Claims (1)

  1. CLAIM
    A concrete, steel or plastic tank or series of connected tanks built on or floated out & scuttled at the end of a sewage outfall these tanks to be aerated by oxygen or air fed from small bore "bleed" pipes laid criss-cross or laterally on the tank bottam.
    After the tank has filled with sewage slurry & aeration begins clarified water rises & is syphoned off for further clarification or discharge into the sea.
