Abstract
Abstract A bacterial incubator device to facilitate organic reduction of waste materials and method of placing it in the waste water collection system, such as in a grease trap, together with the addition of culture strains of bacteria with a high capacity for specific organic reduction, including an enclosure having a foraminous wall structure packed with high surface area elements such as spherical packing of a shape of size to multiply the solid bacterial growth surface area of the location in the sewage collection system and a weight device to cause the incubator to be positioned at the interface of floating scum matter and the water.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
178 words
A method of preliminary biological reduction of waste water flow having an organic matter scum floating at the surface comprising: (a) choosing a location in the waste water collection system where there is significant detention time in the flow, (b) constructing a bacterial incubator means providing a multiple increase in effective solid surface area of the location comprising: (i) an enclosure having a foraminous wall structure to allow essentially unimpeded fluid flow into, out of, and through the enclosure, (ii) a multiplicity of plastic molded foraminous spheres having multiple cross members inside packed into the enclosure of a shape and size to allow essentially unimpeded liquid flow through the enclosure, and (iii) a weight means in the incubator to cause the incubator to be positioned at the interface of organic scum and water layers in the waste water. (c) positioning the bacterial incubator means in the liquid to float at the interface of the scum and the liquid, and (d) adding to the waste water a charge of bacteria cultures having a high capacity for specific organic reduction.

Independent Claim

Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the location is a grease trap, a wet well or a scum pit in the waste water collection system.
