ABSTRACT:
This invention provides a biological injector suitable for biologically treating a fluid flowing through or contained in a collection or treatment system. The biological injector comprises at least one porous section for containing bacterial cultures, at least one non-porous solid section and at least one removable piece which, combinedly, form an enclosed container. Each porous section is attached to at least one non-porous solid section. At least one non-porous solid section is used as a base to which some components of the biological injector can be attached. Each removable piece is attached to one non-porous solid section. The biological injector may include means for fastening the biological injector to a selected location within the collection or treatment system. The biological injector may include means for feeding liquid bacterial cultures and additives to the fluid. When the removable piece is removed, bacterial cultures and, optionally, additives such as nitrogenous salts, phosphorous salts, buffers, surfactants, enzymes and organic substrates, are placed in the biological injector. The biological injector is immersed into the collection or treatment system. Any fluid that passes through the biological injector undergoes biological decomposition.
