Description

BRIEF DESCRIPTION OF THE DRAWING

[0009] The accompanying drawing illustrates the process of the present disclosure of the invention wherein:

[0010] FIG. 1 is a block diagram illustrating the process I method of the beneficial use of by-product water.

DETAILED DESCRIPTION

[0011] The method/process according to the present disclosure is described in conjunction with reference to FIG. 1 as follows:

[0012] Moisture Evaluation: In accordance with the disclosure, a targeted area of soil, preferably near the source of by-product water, is evaluated in block 10 to establish a baseline of soil moisture. This can be accomplished using moisture probes or gauge which can measure the current moisture in the targeted area of soil. The probe, not unlike an automobile oil dipstick, measures how deep from the surface that moisture currently exists. This can range from inches to feet. This metric will change with rain, irrigation, and vegetation use. Thus, the baseline moisture is preferably measured near the time the by-product water is to be applied to the targeted area of soil. The baseline moisture is preferably measured at various selected locations on the targeted area of soil and then averaged or otherwise combined to obtain the baseline moisture for the entire targeted area of soil. The baseline soil moisture is then compared against established agriculture guidelines (block 12) to determine the amount of water that the selected vegetation will need. For example, should the vegetation need 3″ of water depth, but there's only currently 1″ water depth, then an additional 2″ of water will need to be applied through irrigation and the response in block 14 would be yes. If there was no need for additional water at the time of measurement, then the response in block 14 would be no until a later time when testing was once again done to determine the water need.

[0013] Soil Testing: In block 22 the soil itself in the targeted area of soil is tested to establish the chemical makeup of the soil. Samples of the soil, collected at multiple representative locations of the targeted area of the soil, are taken to a lab for evaluation to determine the chemical makeup of the soil. Like the water moisture results, the soil test results provide the current chemical composition of the soil at the specific locations where the sample was taken with a composite chemical composition determined by averaging or otherwise combining the according to any other accepted combining technique to obtain a composite chemical composition measure. A desired chemical/nutrient composition of the targeted soil area is then established in block 24 based at least in part on the nutrient requirements of the vegetation to be grown (block 26). The chemical composition of the soil, the requirements of the vegetation to be grown and a selected or desired optimum chemical/nutrient composition of the soil along with the measured chemical composition of the by-product water (block 20) is then used to define how a batch of the by-product water should be processed to remove, add or modify its chemical composition to achieve the desired chemical/nutrient composition for the soil (block 28) when the processed by product water is applied to the targeted soil area. For example, if the soil is deficient in nitrogen, the processing of the by-product water (block 30) can be done in a way that will leave more nitrogen in the water. If the soil has an abundance of nitrogen, the processing plan (block 28) will be defined so that the by-product water processing (block 30) will remove nitrogen from the water, so as not to have too much. The determination of the proper amount of chemicals that should be in the batch by-product water is referred to as Conservation by Design (“CBD”) and is designed so that the measured soil characteristics are used to determine the makeup of the processed by-product water that is to be applied to the targeted area soil.

[0014] By-Product Water Processing: The by-product water is first put into a batch holding tank (block 16) with a defined volume and preferably located near the by-product water source. In one example, the batch holding tank holds 21,000 gallons (500 barrels). Depending on the volume of by-product water and the acreage to which the process water is to be applied, more than one such batch holding tank may be utilized. From an agricultural perspective, each tank can water an acre of soil approximately one inch deep. Each batch is then identified with a tracking code (block 18) so that should any problems arise with the water's makeup, it is simple to identify which batch is problematic and that batch can be re-processed (e.g., block 32).

[0015] By-Product Water Pre-Test: Once the chemical makeup of the soil is known, a selected chemical make-up for the processed by-product water to be applied to the targeted soil can be selected to adjust the chemical makeup of the soil to be closer to an ideal makeup for the vegetation to be grown. Referring to the previous example, if the soil needs more-or-less nitrogen for ideal growing conditions, the processing of the by-product water will be adjusted to increase or decrease the nitrogen to provide more or less nitrogen to the soil. With an ideal water makeup in mind, the batched water is tested (block 20) to see how close it comes to this ideal. The processing plan (block 28) is then created based on comparing what the by-product water is currently to approximately what is needed for the area of soil (with its current chemical/nutrient composition and the needs of the vegetation to be grown) to more closely align with the defined or desired post-application moisture and chemical composition. In addition to monitoring the potentially “good” chemicals in the by-product water, the “bad” chemicals, such as chlorine, are also identified and their removal is part of the water processing plan. The by-product water is then processed in accordance with the processing plan (block 30). A pre-treatment report of chemical composition of the batch of by-product water is illustrated below.

[0016] By-Product Water Processing: The by-product water is processed (block 30) using a range of available technology units preferably located close to the source of the by-product water eliminating the need to truck or pipe the water to a processing facility. Two methods of processing the by-product water can be used and are ideal for CBD. Water can be processed by heating such that by-product water is heated to differing temperatures to eliminate certain chemicals. Alternatively, the by-product processing can be by reverse osmosis to select some and eliminate other chemicals. Other means of process are also available such as filtering, UV radiation, aerobic processing, anoxic processing, anaerobic processing or any other cleaning process. The by-product water processing plan is then used to process the by-product water into a second batch holding tank.

[0017] Water Post-Test: After the by-product water has been processed into the second batch holding bin, it is tested (block 32) to ensure that the processing is in accordance with the processing plan and the resultant processed water meets processing plan specifications. If not, the processes water is run through one or more processing step(s) again. This can be done by adjusting the processing plan based on the chemical composition of the processed water determined from the test (either in block 32 or block 20, as shown in FIG. 1) or by simply using the same processing plan to reprocess the water as shown by the dashed line in FIG. 1. A typical post processing test report is illustrated as follows:

[0018] Water Application: The processed by-product water is then applied (block 34) to the select area of soil using well known agricultural irrigation technique.

[0019] Ongoing Monitoring: Since the processed by-product water application will in most cased be repeated for growing the crops, trees, or other vegetation, the moisture and chemical composition testing of the targeted area of soil will be periodically repeated (block 36) with appropriate modifications to ensure that the correct amount of water with the correct chemical/nutrient composition will be applied. Based on the vegetation being grown, the soil is also periodically monitored to reveal if the processing plan needs to be adjusted. An illustration of a monitoring report of the chemical composition is as follows:

[0020] While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. For example, the above disclosure has application to carbon sequestration for preserving the environment. In such an application, the processed by-product water generated in arid areas can be applied to large areas of arid soil where vegetation is sparse or non-existent to water vegetation which will have the effect of removing carbon dioxide from the atmosphere and through the process of plant growth and will in effect deposit the carbon dioxide in the ground. Likewise, any carbon remaining in the process by-product water will also be absorbed into the ground rather than released into the atmosphere. Accordingly, the scope of the invention is to be interpreted only in conjunction with the appended claims.
