Program for Kalk reactor

[Bryan]

Hello:

Wondering if someone could post some code for a kalkreactor mixing cycle for a ACjr. Using the osc command to start the reactor mixing pump every 240 minutes for a minute is a no brainer, but I want to shut off my Osmolator for 1hour after the osc cycle,so the kalk can settle. I don't want to use switch inputs /outputs. I suspect I need some dummy timers, but lost on that point.

So basically run Kalk reactor for 1 minute every 240 minutes. When cycle starts turn off Osmolator for 1 hour.

Thanks

Take a look at my AC3 program (online at my website). Note; if this is a Nielsen reactor (as most are these days) then you don't need settle time; even during mixing the top (where water is drawn) should remain clear, if not then you are adding too much kalk.

Thanks, will take a look, need to add a shutdown of at least 1/2 an hour. Uses a maxi-jet to mix and does too good of a job, unless I could only mix for 5 seconds or so which I don't think is possible on the ACjr.

I am using a Osmolator so it will pump the effluent through quickly adding some of the unsettled kalk as opposed to a slow drip from a float valve, where it would not matter.

I used the same setup for a very long time and the top 1/3 was always clear; I mix for 5 minutes. It really sounds like you are overfilling the kalk. Who's reactor is this (or is it a DIY one)?

DIY, chamber about 20" high, 2 " of kalk at the bottom. However I am using a MAxijet 1200 to mix so perhaps that is the problem. Are you recommending that during mixing the "Storm" of kalk should not rise all the way to the top of the reactor?

Yes, a properly balanced and setup Neilson (sp) reactor should not mix to the surface, if you want your pump to last the pump should be taking in clear fluid and pumping it down to the bottom (where the kalk settles).

I can see if you are getting a mix to the top why you would want the settle time and I have program examples to support that (basically, you use a Max Time statement with a time value equal to the mix time + settle time).

Thanks, would you be able to point me in the right direction for the statements for the Max time Statement as you suggested. Will need to do so until I modify the reactor. Thanks for all your help
