Abstract
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises a porous outer covering member which forms an enclosed package with a source of bacterial cultures contained within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.
Claims13
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises:
- (a) a porous fabric outer covering member which forms an enclosed package, and
- (b) a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, and
- (c) said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants.
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises:
- (a) a porous fabric outer covering member which forms an enclosed package, and
- (b) a source of dried bacterial cultures contained on a carrier and confined within said package with said carrier consisting of at least one material selected from the group consisting of bran base, rice hulls and peanut hulls, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.
A method for biodegrading waste flowing through or which has accumulated in a collection system, grease trap, chemostat or bioreactor which comprises:
- (a) providing a porous fabric outer covering member which forms an enclosed package, and which contains a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants,
- (b) placing said package within a waste stream whereby said package seeds said stream with biodegrading cultures.
A method for biodegrading waste flowing through or which has accumulated in a collection system, grease trap, chemostat or bioreactor which comprises:
- (a) providing a porous fabric outer covering member which forms an enclosed package, and which contains a source of dried bacterial cultures contained on a carrier and confined within said package, with said carrier consisting of at least one material selected from the group consisting of bran base, rice hulls and peanut hulls, said cultures being suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream,
- (b) placing said package within a waste stream whereby said package seeds said stream with biodegrading cultures.
