\"\"<\/a><\/p>\n

A balance barometer is a very simple device that provides fool-proof protection of ozone generating equipment in a venturi injection system.\u00a0\u00a0 As someone new to the ozone industry learning how to harness the power of ozone, I was intrigued by the balance barometer I was asked to construct for one of our systems<\/a>.\u00a0 How does it work?\u00a0 Why are they useful?\u00a0\u00a0 Is there anything particular about the dimensions that make it work properly?<\/p>\n

 <\/p>\n

A balance barometer is used to keep water from backing up into the output side of an ozone generator.\u00a0 Corona discharge ozone generators will reliably generate ozone if, and only if, they stay very dry.\u00a0 Any moisture coming into the ozone generator will shorten its life.\u00a0\u00a0 In a system where a venturi<\/a> is used to inject and dissolve ozone in water, a catastrophic flood of water into the ozone generator is always only seconds away.\u00a0 Critical to the success of any such system is that point between the ozone generator and injecting the ozone into the water stream.<\/p>\n

 <\/p>\n

Under normal operating conditions, the venturi<\/a> through which water is forced will create suction and prevent any water from flowing back to the ozone generator.\u00a0 This water will immediately flow to the generator if water flow is reduced or stops in the venturi.\u00a0 A simple check valve is built into Mazzei venturis<\/a> to prevent this backflow.\u00a0 An additional series of stainless steel and Kynar check valves will stop or slow this water most of the time.\u00a0\u00a0 But even “slowing the water” or “most of the time” is a risk that can be eliminated with a simple balance barometer.<\/p>\n

 <\/p>\n

A balance barometer is a U shaped tube with one side about twice as high as the other.\u00a0 The top of the high side is capped off, and two holes are drilled into the cap: one straight down from the top, and one in the side at the bottom edge of the cap for ozone tube fittings. One inch clear PVC works well for visual monitoring, and the diameter allows bubbles and water to pass by one another without hindering its performance.<\/p>\n

 <\/p>\n

So let’s hook it up to see how it works.\u00a0 The very top fitting goes to the ozone generator, and the side fitting just below the top fitting goes to the venturi suction port in our system<\/a>.\u00a0 If sufficient water flows through the venturi, it will begin to draw air through the check valves, ozone generator, and balance barometer.\u00a0 If we put some water in the balance barometer, it will block off air flow through it and force all the flow to pull through the ozone generator.\u00a0 This would be the normal operation.<\/p>\n

 <\/p>\n

Now if the particular water system has some water pressure when water isn’t flowing through the venturi, as in a well water system, water will be forced back out the injection port.\u00a0 The check valve should prevent water back flow, but if ozone has deteriorated the seal or a tiny speck of something prevents a tight seal, water will begin to flow past it and toward the ozone generator.\u00a0 When it reaches the balance barometer, it will simply add water to it until the short end overflows.\u00a0 Once water flow is restored to the venturi, the suction will return.\u00a0 Any water in the line or extra water in the barometer will be sucked into the venturi and normal operation resumes.<\/p>\n

 <\/p>\n

The balance barometer works well with ozone generators that operate under very low pressure or a slight vacuum.\u00a0 Only 1 psi of pressure or vacuum will balance with 27 inches of water making the minimum size short side of the tube for such a system 27 inches.\u00a0 Systems that simply use the venturi to pull air through the ozone generator work well with a balance barometer.\u00a0 If a balance barometer is not practical for a particular application, our stainless steel backflow preventer<\/a> will provide the same type of protection using a built-in float.<\/p>\n","protected":false},"excerpt":{"rendered":"
