It is capable of degassing hydrogen sulfide and radon gas and precipitation of the iron to become a solid and attaching its self to the interior walls and drip screens of the Residential In-well Internal Water Aerator within the well, thus reducing/eliminating the stained fixtures, bad smell and the risk of radon gas from within the residence.

Full Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a water aerator and more specifically it relates to a Residential In-well Internal Water Aerator for the reduction/elimination of iron, hydrogen sulfide (rotten egg smell) and radon gas in residential wells. 
     2. Description of the Related Art 
     It can be appreciated that water aerators have been in use for years. Typically, water aerators are comprised of individual units which stand alone and are separate from the pump and delivery system of existing water systems. The main problem with conventional water aerators is the cost factor required in their set up. Another problem with conventional water aerators is that they are water aerators is the amount of property that is required to install the reservoir or tower. Requirements to achieve the desired aeration process with other water aerators such as mechanical water aerator systems, is the secondary power cost, as well as the ongoing maintenance costs. 
     While these devices may be suitable for the particular purpose to which they address, they are not as suitable for the average residential well in the reduction/elimination of iron, hydrogen sulfide (rotten egg smell) and radon gas. The main problem with conventional water aerators is that they are impractical for the average residence due to the cost factor involved in continuing maintenance, building specialty units and or the construction of a aeration spillway/aeration tower etc. Another problem with mechanical water aerator systems is the amount of property required to install the above aforementioned devices. Another problem with mechanical water aerator systems is the ongoing power and maintenance cost along with the number of pieces of equipment necessary for the aerator to function properly and be fault free. In these respects, the Residential In-well Internal Water Aerator according to the present invention substantially primarily located in reservoirs and water towers. Another problem with conventional departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of the reduction/elimination of iron, hydrogen sulfide (rotten egg smell) and radon gas. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of water aerators now present in the prior art, the present invention provides a new Residential In-well Internal Water Aerator construction wherein the same can be utilized for the reduction/elimination of iron, hydrogen sulfide and radon gas at the well site. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new Residential In-well Internal Water Aerator that has many of the advantages of the water aerator mentioned heretofore and many novel features that result in a new Residential In-well Internal Water Aerator which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art water aerator, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises an aerator nozzle and controls, UV light (optional) drip chambers, GAC (granular activated charcoal) filter chambers in sequence. Each section screws together to create an apparatus that hangs from the well cap. The water is pumped to the aerator by the well pump where the water is misted/aerated and drips through the series of drip screens, UV light (optional in drip chamber # 5 ), two GAC (granular activated carbon) filters to improve the taste and odor. The aeration in turn creates the degassing process of hydrogen sulfide, radon gas, and the precipitation process of iron. 
     This process is a continual recirculation of the water in the well, and allows the Residential In-well Internal Water Aerator to become an iron trap and a degassing chamber away from the premises and within the well casing, therefore continuously reducing the iron content and the degassing of the hydrogen sulfide and radon gas in the water provided to the residence. The Residential In-well Internal Water Aerator will need to be maintained on an as need basis. On a semi regular basis the control valve to the Residential In-well Internal Water Aerator needs to be exercised (closed and opened). This in turn flushes the nozzle and helps prevent the nozzle from clogging. The higher the iron content of the raw water source the more frequently the cleaning process of the Residential In-well Internal Water Aerator will be required. This involves pulling the unit from within the well casing, hosing it down (washing off the iron solids), and reinserting it into the well. This process can be done in about 30 to 40 minutes. This is not a stand alone system. Water is supplied to the Residential In-well Internal Water Aerator by a tap into the main water pipe of the residence directly from the pump at the well casing. Tap may also be done in the garage or basement for easy access to controls. The Residential In-well Internal Water Aerator is a leach system using existing pumps and pipes in turn supplies and rotates the raw source water in the well.

       FIG. 7  is an exploded/overview showing the water supply/controls for the Residential In-Well Internal Water Aerator. It will be necessary to expose an area about not less than 2′ wide by 4′ long to provide access to of the primary water supply line  104  from the pump to the house on the outside of the well casing  101  to allow for the necessary tap. A hole will also need to be drilled offset of center in the top of the well casing cap  102 . (Be sure to note the location of the existing pitless adapter or well seal before drilling the hole in order to allow room for the Residential In-Well Internal Water Aerator in the well casing.). The tap will be made by cutting the primary water supply line  104  and inserting a tee  106  held in place by two hose clamps  105 , on each side of the supply tee  107  that is inserted into the primary water supply line  104 . A bushing  107 , is inserted into the tee  106 , followed by a nipple  108 , a ball valve  109 , nipple  108 A, tubing adapter  110 , high pressure tubing  111 , an adapter  110 , 90 degree street ell  112 , a flat washer  113 , a nipple  108 B, inserts through a flat washer  113 , a galvanized coupler  116  and a spray nozzle  117 . The street ell  112  becomes the support bracket on the topside of the well casing cap  102  for the Residential In-well Internal Water Aerator Residential In-well Internal Water Aerator. Three nozzles  117  are included interchangeable for light iron, medium iron, or heavy iron concentration in the well water. This allows the customer to customize the Residential In-Well Internal Water Aerator to their individual need. 
       FIG. 8  is an exploded/cross section view showing an internal drip aeration screen  124  in detail ( 124 A top view of same) for the third chamber  128  fourth chamber  127  and fifth chamber  118 . A total of four internal drip aeration screens (each 13¼″ lone and range from 1¼″ to 2″ in diameter) are inserted vertically into each of the third chamber  128  fourth chamber  127  and fifth chamber  118 . Once the water is misted into the fifth chamber  118  it goes through a drip process by which hydrogen sulfide is degassed. Additionally suspended iron solutions are precipitated into a solid that attaches to the drip screens thereby reducing iron solids from the raw water source. 
       FIG. 9  is an exploded view of an optional UV light  125  to be centrally inserted into the fifth drip chamber  118  held in place by the internal drip aeration screens  124 . The electrical wire includes the waterproof hook-up wire leads  123 , waterproof electrical box  133 , twist on wire connectors for UV light internal source  134 , and waterproof wire connectors for external source  134 A which in turn requires an electrical hook-up at the pump site. 
       FIG. 10  is an exploded view showing the installation rod  120  in place in the fifth chambers  118  (also applicable in the fourth chamber  127 , third chamber  128 , second chamber  130  and first chamber  131 ) during installation and removal of Residential In-well Internal Water Aerator in/from the well casing  101  allowing for hands free installation/removal. Alternatively, the third chamber  128 , fourth chamber  127 , and fifth chamber  118  ( FIGS. 4 ,  5 , and  6 ) may need to be modified per size of the well casing  101  and placement of the pitless adapter/well seal in each individual well. Another alternative to the tap in the primary water supply line may vary depending upon the use of pvc, galvanized, brass or other piping material  104 . Another alternative is if the user chooses to run a high pressure tubing line  111  from the well casing to the basement or garage so the ball valve  109  can may be located inside the basement or garage. Another alternative is using drip screens in place of GAG with or without GAG. Another alternative is the use of green sand or zeolite in place of GAC. Another alternative is that the pattern of the aerator drip screens  124  and ( 124 A for a top view of the same) may be round instead of square. Another alternative would be a single aeration screen approximately 53″ long. Another alternative is with or without UV light  125 . In the cases with UV light  125  the UV exposure will meet or exceed N.S.F. (National Sanitation Foundation) minimum requirements. The UV light  125  will require water proof wire leads  123 , a waterproof electrical box  133 , wire nuts connectors  134  and  134 A and waterproof tape  137 . The UV power source will may come from the pump power source at the well site. For this option a utility box will need to be added at the well site.
