News editors obtained the following quote from the background information supplied by the inventors: "As the density of urban populations increase, so does the amount of sewage that is generated. Sewage is known to be generated by residential, institutional, commercial and industrial establishments. Sewage includes household waste liquid from toilets, baths, showers, kitchens, sinks and the like and is disposed of via sewers. In many areas, sewage also includes liquid waste from industry and commerce. As water is one of the greatest needs of any community, the treatment of this wastewater to preserve good, quality water, is of paramount importance.
"In general, the wastewater treatment process is similar to the natural process by which water is cleaned while moving through a river. Early on, towns and communities pumped raw sewage from homes, businesses and factories directly into rivers, streams, lakes and oceans. As human populations grew, this practice degraded the water quality to the point of posing serious health hazards. Increasing growth and development created a demand for clean water that exceeded the rate at which it could occur naturally in streams and rivers. At one point, many rivers and streams were so polluted that sewage posed a health risk. Changes in national policies, such as the Clean Water Act, created broad sweeping legislation that led to the construction of many wastewater treatment plants and a national focus to improve our national waters.
"Accordingly, collection systems have been developed to transport the wastewater from homes, businesses and industry to wastewater treatment plants in order that it is subjected to a treatment process. Wastewater treatment today, in its various forms, still contains treatment processes that utilize soil and water microorganisms to convert the organic substances in wastewater into harmless materials.
"Various wastewater purification processes are known in the prior art. An exemplary wastewater purification process is disclosed in U.S. Pat. No. 6,447,687, issued to
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "The present disclosure provides a method for improving the wastewater treatment process by injecting an additive agent into the wastewater stream prior to injecting polymers into the wastewater stream for the purpose of thickening the raw sludge to reduce odor produced by the organic materials and the mercaptans.
"The present disclosure improves the wastewater treatment process by decreasing the amount of sludge that needs to be disposed of and reducing the foul odor produced by the organic materials and mercaptans disposed in the wastewater stream.
BRIEF DESCRIPTION OF THE DRAWINGS
"Other aspects of the present disclosure will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
"FIG. 1 is a schematic view of a wastewater purification process in accordance with the present disclosure; and
"FIG. 2 is a schematic view of a solid treatment process used in conjunction with the wastewater purification process shown in FIG. 1."
