System For Controlling Addition Of Lime To Reduce Water Alkalinity
US Patent:
5340468, Aug 23, 1994
Filed:
Mar 31, 1993
Appl. No.:
8/040661
Inventors:
William H. Hawthorne - Thornton CO
Gary J. Herbert - Thornton CO
Gary J. Herbert - Thornton CO
Assignee:
Hawthorne Treatment Systems, Inc. - Thornton CO
International Classification:
B01D 1712
US Classification:
210 961
Abstract:
A system for regulating the addition of lime to reduce water alkalinity includes two sensors for measuring the conductivity of the water prior to and after addition of lime, a pump for adding lime to the water, and a controller for regulating the pump. The controller periodically samples the conductivities measured by both sensors and computes the ratio of the conductivities for each sample as well as the slope of the ratio between samples. The controller turns the pump off when the conductivity ratio exceeds a predetermined maximum set point and the slope is positive, and turns the pump on when the conductivity ratio falls below a predetermined minimum set point and the slope is negative.

International Classification:
B01D 61/00
US Classification:
210639000, 210641000, 210650000, 210758000, 210806000, 210764000, 210259000, 210202000
Abstract:
The present invention is directed to various sets of unit operations for treating aqueous effluents and logic for designing and effecting the treatment. The unit operations include stabilization of subterranean waters, sequential oxidation steps to alter selected target materials, oxidation to break up emulsions prior to removal of the emulsion components, and intense oxidation to break up difficult-to-remove organic target materials.
