ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a water purification system and more particularly pertains to recirculating wash water while removing impurities therefrom.
2. Description of the Prior Art
The use of water treatment systems of known designs and configurations is known in the prior art. More specifically, water treatment systems of known designs and configurations previously devised and utilized for the purpose of recirculating water through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 836,323 to J. W. Keegan discloses a process of sewage disposal. U.S. Pat. No. 5,228,995 to Stove discloses a biochemically enhanced hybrid anaerobic reactor. U.S. Pat. No. 5,496,469 to Scraggs, et al. discloses an apparatus for reducing and separating emulsions and homogenous components from contaminated water. U.S. Pat. No. 5,503,709 to Burton discloses an environmentally improved process for preparing recycled lignocellulosic materials for bleaching. U.S. Pat. No. 5,647,977 to Arnaud discloses method and apparatus for removing contaminants from industrial waste water. Lastly, U.S. Pat. No. 5,906,745 to Eto discloses an apparatus and method for purifying polluted water.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a water purification system that allows recirculating wash water while removing impurities therefrom.
In this respect, the water purification system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of recirculating wash water while removing impurities therefrom.
Therefore, it can be appreciated that there exists a continuing need for a new and improved water purification system which can be used for recirculating wash water while removing impurities therefrom. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of water treatment systems of known designs and configurations now present in the prior art, the present invention provides an improved water purification system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved water purification system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a new and improved water purification system for recirculating wash water while removing impurities therefrom. First provided is a housing. The housing is formed in a generally rectilinear configuration. The housing has a rectangular floor and long side walls. The side walls are in parallel relationship with respect to each other. The housing also has a short input end wall and a short output end wall. Each of the walls has an upper edge spaced a common distance above the floor. An inlet line is formed in the input end wall adjacent to the upper edge for water to be purified from a cleaning area. An outlet line is provided adjacent to the floor. A horizontal support plate is formed as an extension of the floor adjacent to the output end wall. A covering is provided over the housing. A plurality of vertical baffles are next provided. The baffles are coupled between the side walls of the housing. Each baffle has an upper edge and a lower edge. The baffles include a first baffle adjacent to the input end wall. The first baffle has a lower edge spaced from the floor and an upper edge spaced a first distance from the upper edge of the housing to allow the flow of water there beneath. A second baffle is included adjacent to the first baffle. The second baffle has a lower edge adjacent to the floor and an upper edge spaced a second distance from the upper edge of the housing greater than the distance of the upper edge of the first baffle to allow the flow of water there over. A third baffle is included adjacent to the second baffle. The third baffle has a lower edge attached to the floor and an upper edge spaced from the upper edge of the housing at a distance substantially equal to that of the first baffle to allow the flow of water there over. The baffles also include a fourth baffle adjacent to the third baffle. The fourth baffle has a lower edge spaced from the floor a distance greater than the first baffle and the third baffle and an upper edge in proximity to the upper edge of the housing to preclude the back flow of water from adjacent to the output end wall toward the input end wall. Lastly, a fifth baffle located between the fourth baffle and the output end wall is provided. The fifth baffle has a lower edge attached to the floor and an upper edge spaced from the upper edge of the housing at a distance substantially equal to that of the first and third baffles. Next provided is a rectilinear array of media, such as corrugated plastic. Media located in the space between the first baffle and the adjacent end wall allows for the flow of water downwardly there through. Media located between the first and second baffles allows for the flow of water upwardly there through. Media located between the second and third baffles allows the flow of water downwardly there through. Bacteria, such as pseudomonas, is next provided. The bacteria is in the housing located on the surface of the media. The bacteria assists in the biological purification of the water flowing there through. Next provided is an air flow system. The air flow system includes an air pump. The air pump is located on the support plate. An associated first air pipe is provided. The first air pipe extends from the pump. A plurality of lateral pipes and aeration heads are provided. The lateral pipes and aeration heads are coupled with respect to the first air pipe and are located in the first chamber, second chamber and third chamber beneath the media and allow for the flow of air through water moving through the media. An overflow is provided so that the water in the treatment chambers is maintained at the correct level. A water flow system is next provided. The water flow system includes a pump. The pump is located above the support plate. A filter is provided. The filter is located on the support plate. A water inlet line is provided to move water from the housing through the pump and then through the filter and then to water outlet connections for final use. Operator controlled handles are provided. The water flow system further includes an arcuate support for a hose located above each outlet connection and an associated reservoir on the support plate to maintain pressure within the water moving through the water flow system. A water inlet orifice is provided in the output end wall. The inlet orifice functions to provide supplemental makeup water to the housing. A float valve is provided. The float valve is located within the housing to allow for the addition of make up water when the water supply within the housing is less than a predetermined level. A control panel is provided. The control panel has a plurality of operator control knobs. The control knobs include a switch for main power, a switch for process pump power, a switch for blower power, and a switch for pressure pump power. A plurality of sensor meters are provided. The sensor meters including an hour meter for process pump operation, an hour meter for blower operation, and an hour meter for process pump operation. Lastly, an associated feeder mechanism is provided. The feeder mechanism is on the exterior surface of the outlet end wall. The feeder mechanism contains a quantity of supplemental bacteria adapted to be fed into the housi
