First of all this system is mainly for fish room applications or a really, really large stand
. I have used it for 3 years now without any problems. I consider it to be one of the safest and most stable methods available The tank itself is a diy fifty gallon acrylic tank but could be bigger or smaller without a problem. The float valve controls the rodi water and regulates the level in the the mixing tank. There is a safety overflow at the tank to direct water away and down a drain ,should the float valve fail. My total rodi system is set on a timer for operation once a day and to prevent short cycling. I like to use maxijet mods on digital timers to do the mixing.
The standpipe in the tank prevents slurry from entering and settling in the supply line . I purposely left the maxijet on for 12 hrs and the slurry never entered the sump. The supply line is about 8' long as well which would help prevent slurry from entering the sump since the effluent is only dripping. This differs from using a ato to supply the kalk which would dump the slurry should the stirrer or mixing pump stick on. The needle valve is a plastic valve available from usplastics.com . The only failure I can think of for the needle valve is it might clog and reduce the drip rate.(no big deal). I do open the valve up and run a steady stream for a couple minutes every 6 months or so.
I set the (24/7) drip rate during the low evaporation rate of the summer months and leave it at that all year. I would recommend not setting the tank above your sump in case a rupture occurs in the tank.
I hope some one can benefit from this and please bring on feed back.
By the way this is an open top so I am sure that the question will come up about the atmosphere's effect on the potency of the kalkwasser.That was tested and shown to have very little impact.
