US Patent:

8051383, Nov 1, 2011

Filed:

Feb 29, 2008

Appl. No.:

12/040716

Inventors:

Christopher T. McCampbell - Foothill Ranch CA, US
Steven M. Dishon - Mission Viejo CA, US
Martin T. Scanlan - San Diego CA, US

Assignee:

Integrity Municipal Services LLC - Poway CA

International Classification:

G06F 3/048

US Classification:

715771, 715772

Abstract:

The graphical controller provides a graphic user interface for monitoring and managing multiple chemical feed constituents, and displays a breakpoint curve specific to water being treated and a given ammonia set point, based on operator input and data from measurement of total chlorine, free chlorine, monochloramine, combined chlorine, ammonia residual, and the like. The graphical interface determines where on the curve the process is, provides immediate visual feedback to the water treatment operator and allows control of chlorine and ammonia feed rates to a fixed or new chloramination and ammonia set point.

Roop C. Jain - San Diego CA

Assignee:

RJ Environmental, Inc. - San Diego CA

International Classification:

C23F 1104
A62B 708
B01D 5000

US Classification:

422 12

Abstract:

An odor control system and method for removing unwanted odorous airborne constituents in which the gas stream is flowed through a compact, boxlike housing having a plurality of sequentially communicating treatment chambers. Gas stream pretreatment is accomplished in a first chamber, in fluid communication with a sump, as the gas flows through a packed bed wetted by suitable chemical reagents. After pretreatment, the gas stream is passed through downstream chambers, also utilizing wetted packed beds. These chambers are in fluid communication with a second, separate sump. Because of the first chamber/separate sump combination, influent gas treatment, by stages, can be accomplished. In this manner, different, contemporaneous chemical treatments are possible, within the single housing, with different chemical reagents utilized as needed. Such treatments are possible even in cases where otherwise incompatible chemical reagents are used. Reagents used in the first chamber are, in substantial part, recycled from the blowdown of the first chamber sump which can be augmented, if desired, by unreacted chemicals in the blowdown of the downstream sump.
