High Tech Automation - Saltwater Mixing Station

[SaltwaterAq Verified Sponsor]

In this Video we walk you through a fully automated RODI Saltwater mixing station using a spectrapure maxcap ultra high efficiency 200 GPD RODI unit, a Neptune apex and various sensors & float valves. We cover topics like redundancy, high end mixing stations, fish room project design, remote access, containing spills, ro membrane flushing, water level sensors, etc.

Heads up on the 1/4" flow sensor (in case you don't already know) - they aren't very accurate. It takes almost a full pressure flow in order to get them to spin, and with the reduction in pressure from the membranes and waste water draw, there's almost not enough to cause it to spin. I tried to use mine as an indicator of membrane life, but so far it functions as only a semi-reliable on/off indicator. Not nothing, but not what I hoped for either...

Two things I'm still looking for:
1) Same as you - salt hopper that would allow me to punch in a weight and have it dump that into my mixing tank
2) TDS meter integration with the Neptune; I'd love to know when the resin is low, input water spiking (water softener needs replacing), or membranes aren't as effective as they should be

Thanks (as always) for the vid!

Thanks for the info, I'll pass it on to mark.

This is why the sensor was put BEFORE the RODI unit.

Makes sense, yeah. You don't get a flow rate into the holding container, but that should be a fairly constant percentage drop...

Time to alter my setup a bit - thanks for the tip!

You're welcome! Thanks for watching.
