OZONE BACTERIA SYSTEM

This picture illustrates the typical ozone based residential water treatment system for a severely contaminated well and/or that has been found to be positive for bacteria.  System Operation:  Water supplied by the Well Pump (1) is sent through the Re-circulation Pump (2) to the Venturi Injector (3).  At the narrow section of the Venturi a suction is v\created by the water flowing through it.  This suction draws outside air into the Automatic Air Dryer (4) and through the Ozone Generator (5) where the ozone is produced.  The ozone (red line) is drawn into and dissolved in the water by the mixing action of the Venturi.  The ozone attacks the water contaminants as the water/ozone mix flows to the Contact chamber (6).  The gas/liquid mixture then flows through the Off Gas Chamber (7) where excess gas is vented to the atmosphere via the Vent Valve (8).  The water is then stored in the Bladder Tank (9) under pressure, until required for use in the home.  Upon demand the Bladder Tank forces water through the Filter (10) where the oxidized contaminants are removed.  Following the Filter the water can be softened and/or treated with a reverse osmosis system as desired.  Re-circulation Loop Operation:  The foregoing discussion applies to a single pass ozonation of the water.  However is cases of high levels of hydrogen sulfide, metals, tannins and/or bacterial contamination, the re-circulation loop is necessary.  When the house demand for water is made, the adjustable Re-circulation Timer (11) starts the Re-circulation Pump and Ozone Generator and keeps them running for a preset time period following the shut down of the well pump.  While there is no demand for water in the house, it will flow through the Re-circulation Loop (12) on a continuous basis, being repeatedly ozonated until the timer stops the Re-circulation Pump and Ozone Generator.  The Check Valve (13) prevents reverse re-circulation water flow.  The extended treatment builds a powerful ozone residual in the water to ensure the complete destruction of the contaminants including bacteria, viruses and cysts.  Additional disinfection can be obtained by lengthening the re-circulation time period and/or up-rating the ozone generator or both.  This system has proven extremely effective in treating severe water contamination problems not resolved by traditional water treatment technologies.
