Thanks to everyone that has contributed to this discussion.
In response to Dave's questions, Yes, we do use an air partialisation valve to control the amount of air bled into the siphon neck and thus control the flow rate rate. The primary function is to control the water flow rate through the...
Here is the updated sketch - forgot to uploadhttp://files.engineering.com/getfile.aspx?folder=4e1429bd-5fef-430c-bb83-37e61c67f5c2&file=Syphon_Sketch.pdf
Please see an updated sketch of the siphon system. This is a gravity filter system and we use the siphone outlet to regulate the flow rate through teh filter. we are trying to downscale teh unit to build a small pilot plant
The attached sketch refers to an air regulated siphon which consists of two concentric pipes with the ability to control the flow of water using air. Water flow is up the inner pipe, diameter (Da) and then down the second pipe, diameter (Db). When flowing down the outer pipe, the water is...
