Abstract

The present invention is process for irrigation of a golf course, which involves monitoring reclaimed water, and treating it when necessary to avoid harmful effects to plantlife. The reclaimed water is tested with a plurality of monitors to obtain results for water quality characteristics, including: total organic carbon compounds; pH; residual chlorine; chlorides; and, sodium. These results are inputted to a computerized data handling system for data collection, storage and analysis for comparison to predetermined acceptable ranges for water quality characteristic, and to show any deviation from said acceptable ranges. Either alarms are set off or treatment occurs or both, when deviations are observed. Treatment includes a dechlorination system and an oxidation system to correct active chlorine and total organic compound levels, respectively. Other important monitors may be included for one or more of the following: hardness; turbidity; alkalinity; conductivity and nitrates.

Dependent claims

A process for irrigation of man-made landscaped areas, which comprises:

(a) procuring a supply of reclaimed water selected from the group consisting of treated sewage wastewater, untreated sewage wastewater and natural water supply water containing sewage wastewater;
(b) subjecting said reclaimed water to a plurality of monitors and testing said reclaimed water with said plurality of monitors to obtain a plurality of test results for water quality characteristics, including:
(i) total organic carbon compounds;
(ii) pH;
(iii) residual chlorine;
(iv) chlorides;
and,
(v) sodium;
(c) inputting said test results to a computerized data handling system for data collection, storage and analysis for comparison to predetermined acceptable ranges for each of said water quality characteristics, and providing feedback to show any water quality characteristic deviating from said acceptable ranges;
(d) providing a dechlorination system to said reclaimed water for treating said reclaimed water with a dechlorination agent to maintain a level of residual chlorine below a predetermined maximum of said predetermined acceptable range, and activating said dechlorination system in response to feedback from said computerized data handling system when showing deviation from said predetermined acceptable range for residual chlorine;
(e) providing an oxidation system to said reclaimed water for treating said reclaimed water with an oxidizing agent to maintain a level of total organic compounds below a predetermined maximum of said predetermined acceptable range, and controlling said oxidation system in response to feedback from said computerized data handling system when showing deviation from said predetermined acceptable range for total organic carbon compounds;
and
(f) irrigating a man-made landscaped area with reclaimed water which has been processed in accordance with the preceding steps.

and
(f) irrigating a golf course area with reclaimed water which has been processed in accordance with the preceding steps;
wherein said predetermined acceptable ranges are set within the following ranges:
(i) for total organic carbon compounds, 0 milligrams per liter to 50 milligrams per liter;
(ii) for residual chlorine, 0 milligrams per liter to 1 milligrams per liter;
(iii) for pH, 6 to 8;
(iv) for chloride compounds, 0 milligrams per liter to 70 milligrams per liter;
and,
(v) for sodium, 0 milligrams per liter to 70 milligrams per liter.
