BTW, I gave you the specific explicit precise directions of my "trick" as cartonykid Tommy called it, a few days ago and you have been questioning them ever since.
Call it a retention tank or a precipitation tank, doesn't really matter as long as it has a drain at the bottom to remove sediment or precipitants.
Air injection systems using a precipitation tank uses the tank for two purposes; one--to oxidize iron (and other elements) into ferric state and two--to create dissolved oxygen levels of 15% or more in the water to be even and consistent in order to make the BIRM work effectively.
If the water coming out of the top of the precipitation tank is already ferric (red water), then I recommend draining the precipitants more often. If ferric iron is chronic, then I would recommend adding Filter Ag to the top of the BIRM. I don't believe BIRM is intended to filter but to act as a catalyst in enhancing iron conversion.
Water enters the tank through an elevated tube and exits through the top. The tank has a drain lower than the incoming tube. Neglecting to drain the precipitants causes the precipitated iron to accumulate and rise above the incoming tube, causing it to agitate and travel north out of the tank.
That is also from the link above, repeated here;
Two serious errors in one post Andy.... and I didn't count the one where you skipped over retention/contact time. And what is that picture supposed to show us?
"cartonykid" I can't find this word in the dictionary and spell check is having a hemorrhage with it too. LOL
If it's supposed to be cartoon(y) kid, I'm not the one with Donald Duck for an avatar which BTW is nice but incorrect for the quote below it which is more correctly associated with Porky Pig.
Why are you dragging me into this? I'm just by-standing watching the fun although what I have gleaned from this mostly useless and stupid conversation is that there is a lot of misunderstanding on both sides and the juvenile need to make sarcastic remarks based on improper word use or poor descriptions of either processes, equipment or both. Keep it up though, it's most entertaining and perhaps the guy that lambasted me on another thread for remarks I made there has by now noticed that I am rarely the instigator here. LOL

Wow, who'd a thunk. They are just making up words now aren't they?
Someone is making up words...
Yeah I've noticed that too, like "oversaturated", once something is saturated, you don't get it more saturated. Or, "precipitation tank" for retention tank. Or garden hose to hook to a sprinkler that isn't a type of irrigation.
BIRM does not oxidize iron. It is a catalyst. That would be like saying stepping on the gas makes your car go forward. It doesn't. It increases the speed but doesn't make it go forward. A catalyst increases reaction but it doesn't make it react. That is the ultimate basics in water treatment media. You said it yourself when you quoted the word "enhance". But tio say that BIRM oxidizes iron is not correct. You need to understand what catalyst is and does.
Also not correct--again--in describing me...it's getting kind of funny. I am not sure what works for Kinetico or why that was even brought up---again. But I seem to remember someone going on and on and on and on and on about the Kinetico warranty and then being proven he was wrong. Instead of coming back and admitting, he claimed that Kinetico, Inc. was keeping him in the dark---again.
If you don't know what the picture is, then I am not surprised by your knowledge (or lack thereof) of just what it is we are talking about. Can someone else help him here?
since we are not allowed to use technical terms like catalyst, words that have more the three syllables, nor are we allowed to use math, charts, field experience, or common sense, I am sorry but I dont think I can be of much help either.
Precipitation tank - According to wordnik dot com, a receptacle into which a liquid is run to give an opportunity for any solid matter carried in it to be precipitated. Sometimes precipitation is promoted in such a tank by adding certain ingredients or by a change of temperature.
According to science dictionary, a sewage tank in which a chemical is added to the sewage before it passes to the sedimentation tanks
Retention tank - According to my research, mostly used to remove E. coli or coliform. "The use of retention tanks for iron bacteria, sulfur and iron applications is a way to create extra income and service calls for in home sale companies and online companies who are either ignorant or looking for residual income from unsuspecting customers." http://www.***********.com/retention_tanks.htm
Another site says: THERE IS A DRAIN AT THE BOTTOM OF THE TANK. OPEN IT PERIODICALLY TO FLUSH THE SETTLED SOLIDS OUT. SOLIDS DO NOT SETTLE PERFECTLY. OFTEN THEY WILL STICK TO THE SIDE OF THE TANK. THE MOST EFFECTIVE WAY TO FLUSH THEM OUT IS TO EMPTY THE TANK. OPEN THE INLET AND ALLOW WATER TO FLOW IN WHILE THE DRAIN IS STILL OPEN. THIS WILL ALLOW THE TANK TO BE CLEANED MORE THOROUGHLY. RUN THE WATER UNTIL IT APPEARS CLEAR. (LL, based on your iron problems, you might consider doing this if you haven't been already. Just a thought.)
