Embodiment Construction

[0039] in such as Figure 1 to Figure 3 In the illustrated embodiment of the apparatus of the invention, a biotank for bioremediation of soil contaminated, for example, by petroleum products, comprises a large container 1, usually sized to hold an appropriate amount of soil, e.g. 5 to 20 cubic meters. The container may be a conventional skip of suitable size or a suitable container with the top removed, of course, or may be any other suitable sized container, even custom made for the purpose. Extremely long tunnels may be used, which may be self-supporting or may be located in temporary or permanent trenches excavated at least partly from the earth's surface, which of course also falls within the scope of the present invention.

[0040] Such elongated bio-troughs are several meters in length and can reach 100 or even 300 meters, depending on convenience and circumstances.

[0041] Returning to the present embodiment of the invention, the bottom 2 of the container is covered ...

Abstract

A method and apparatus are provided for conducting a microbiological process on a bulk material in which a quantity of the bulk material is loaded onto a waterproof lining forming part of a bio cell with a heat transfer arrangement below the quantity of bulk material or within its volume, or both. The moisture content of the bulk material is controlled by periodic or intermittent distribution of water into the bulk material in order to promote microbiological activity within the bulk material by means of microbes that may be either naturally occurring within the bulk material or may be selected and introduced into the bulk material according to a desired result. A leachate recovery installation collects leachate draining from the bulk material. The temperature within the bulk material is monitored and the temperature controlled in order to elevate or decrease the temperature thereof to approach a target temperature associated with enhanced microbial activity of microbes present within the bulk material. The apparatus includes a controller having an electronic micro-processor with the controller having inputs for association with a temperature detector and a moisture detector. The preferred apparatus includes solar powered thermal and electrical energy units.

Description

technical field [0001] The present invention relates to an energy-saving plant and method for the microbial treatment of bulk materials such as soil, sand, granular ore, water, subdivisions (sub- divided) biodegradable waste, and possibly other subdivided bulk materials capable of microbial treatment. [0002] The present invention relates specifically, but not exclusively, to energy-sufficient microbial processing, particularly utilizing self-sustaining, low-cost in-tank renewable energy, where biological processing is used to dispose of bulk materials in order to purify or bioconvert them into more environmentally friendly products or components extracted therefrom. The biological treatment preferably involves the use of naturally occurring microflora / biofa in order to obtain the desired biological activity within the bulk material. This microbial community can include archaea, eukaryotes, and even viral communities. [0003] In one important application, the invention is...
