System for decomposition of organic compounds and method of operation

An aerobic method for decomposition of aqueous organic waste comprising:

• providing a treatment system comprising:
• (a) at least a first processing container including sides, the container having a capacity from 100 m3 to 30,000 m3 and provided with an upper opening with an area from 100 m2 to 20,000 m2, a substantially horizontal floor with an area from 100 m2 to 10,000 m2 and a depth from 1 m to 3 m;
• (b) an inlet for waste or waste water to be treated in the first processing container and an outlet for water treated in the first processing container;
• (c) at least one channel arranged at the floor having an upwardly opening mouth for collecting moulds, worms or worm-like living organisms, parasites and other sediments, the channel having a width less than 0.5 m and a depth from 0.5 m to 1 m;
• (d) a ventilating pipe extending above the mouth, the ventilating pipe having a multiplicity of apertures;
• (e) a supply of a gaseous additive comprising one or more gases selected from carbon dioxide, ammonia, sulphur dioxide and hydrogen sulphide;
• and
• (f) a compressor and a mixing head connected to the ventilating pipe and arranged to provide a mixture of compressed air and the gaseous additive to the ventilating pipe to discharge a stream of the mixture from the apertures into the water in us;
• and
• the method further comprising introducing waste or wastewater to the inlet of the treatment system.
