Treatment Plant. Running Air Pump Intermittently

[Jenki]

This has been discussed on here before.   My treatment plant runs 24/7. That is the Compressor runs 24/7.  I have read that switching it off there is a chance that water can syphon up the air tubes.  SO I was wondering if I was to turn it on and off hourly I would reduce the risk of any damage by syphoning and reduce the running costs by 50%  We have a large plant 12P  and currently only 2 people using it.

when the cabins are fully occupied then this may jump but the reality I only ever see 6/8 people  max every day.  (it was sized by SEPA- I had no choice)

 

I have found this little board that does what I need, turn on for x time, turn off for x time repeat.

any thought on this as a plan would be appreciated. 

 The setup would be temp, until the house is built then I may come up with a better solution but for now the treatment plant is plugged in, so was going to put this in line just after the plug.

My Graf plant runs 6 mins on and 4 mins off, or it could be the other way around. 

I was told this optimised electricity usage and stops the air holes blocking with crud if the blower is off for longer.

Yes this is one of the reasons I went with our Graf One2Clean. Plus the control unit can be mounted in a remote box up to 25m away. I also got the 7 PE for a decent price which always helps the decision making 😂

The timer is variable. So could do 5mins on and off. Good to hear this is already a thing...

Give it longer on/off periods and it turns into a SBR (small batch reactor), as there's settling time then.

I use one of these timers for controlling my pumping station (so the pump runs for 5 seconds every 40 minutes in my case). It probably does the same as your circuit board but the packaging might be more convenient for you.
