Now I like making things but have been nomadic over the past 5 years and so do not have as many tools as I'd like.
Thought of making a Cerges style reactor but then thought of settling for a commercially available inline diffuser.
Then I saw this thing by Jaqno called a prefilter and something clicked in my head.
Right now, with the water coming from the top, it can only handle a low rate of 1bps before the CO2 builds up and the bubble gets into the path of the incoming water but I suppose with a L shaped elbow, I should be able to get the water to swirl and have the reactor able to handle a much higher injection rate.
Come to think of it, there's a simpler solution. No swirling needed. The prefilter comes with two media separators. All I need to do is to stack them inside and place a fine mesh to prevent any CO2 bubbles from being sucked into the outflow at the bottom.
Now I'm a bit of a jack of all trades, master of none kind of guy so please correct my physics anytime but the way I look at it, even with no swirling to increase contact time, if the bubbles are caught by a mesh, there's no way that a 3 - 4bps rate can generate enough buildup to force the water level from the 2000l/h flow completely out from the chamber.
