air-water ratio dtermination
(OP)
I have an atmospheric water sump tank with a pump. I need to pump the water out to a river through several miles of pipe. I need to add an air/water separator in the line before it reaches the river, so that all the entrained air can come off before water enters the river. The pipeline goes up several hills and then goes down hill into the river.
How do I determine how much air to water ratio I have to size the separator?
By the way, the line will be pigged at the start up to get all the air out. The customer does not want air bubbles coming out on continous basis when the system is running. That is why we need an air/water separtor before water gets to the river.

RE: air-water ratio dtermination
The piping configuration on the Launcher Skid if properly valved will prevent any entry of air.
I do not see how air re-enters the system unless your pump is cavitating - in which case those bubbles are the least of your problem.

Water almost always has entrained air that is released in pipelines, hence air valves are used to release it at high points along a pipeline.
cavitation does not produce long lasting air bubbles. When the water reaches discharge pressure, those bubbles have collapsed due to the higher pressure.
ratash,
You might not need a separator. Have you considered air release valves?

Thanks - I learnt something
RE: air-water ratio dtermination
Who is the manufacturer of these valves, and what kind of valve is it? Our route has several high points. Thanks-
RE: air-water ratio dtermination
Please disregard my last question, I found the information on those valves.
If you were to figure out how air can be entrained, how would you arrive at that number? My pressur eis about 100 psig.
RE: air-water ratio dtermination
Please disregard my last question too. Your mention of air release valves helped a lot. Regards- RATASH
