Abstract
The methods and systems provide for the improvement in the separation of different portions of solids particles, such as bacteria, from a process stream. The methods use gas and control of fluid flow within a tank zone to provide for separation that is more selective.
Claims11
A system for selectively separating solids from a process stream comprising:
- a clarifier which receives the process stream from a process reactor and removes a part of the solids from the process stream to produce a reduced solids stream;
- a separation tank which receives the reduced solids stream from the clarifier, the separation tank having an upper portion having an upper outlet, a lower portion having a lower outlet, and a mid-portion between the upper portion and lower portion, the mid-portion having a mid-outlet;
- and
- a gas flow device which introduces a gas containing stream into the separation tank such that gas bubbles are generated in the reduced solids stream so that the gas bubbles attach to a first portion of the solids particles thus promoting upward flow of the first portion of the solids within the separation tank such that the first portion of the solids are removed through the upper outlet, a second portion of the solids are removed through the mid-outlet and a third portion of the solids are removed through the lower outlet.

A system for selectively separating solids from a process stream comprising a process liquid containing solids particles, the system comprising:
- a clarifier which receives the process stream from a process reactor and removes a part of the solids from the process stream to produce a reduced solids stream;
- a separation tank which receives the reduced solids stream from the clarifier, the separation tank having a plurality of portions, each of the plurality of portions having an outlet;
- and
- a gas flow device communicated with the separation tank, wherein a gas containing stream communicated into the separation tank from the gas flow device generates gas bubbles in the reduced solids stream and wherein the gas bubbles attach to a portion of the solids particles and promotes upward flow of the portion of the solids to which the gas bubbles are attached such that the portion of the solids to which the gas bubbles are attached are removed from an uppermost of the plurality of portions in the separation tank.
