Inline reactors Carbon and GFO

[nickg]

Should I flow through GFO or Carbon first? Also how much flow for each?

 

[rjrgroup]

Carbon first, enough flow to just barely tumble the gfo in the second chamber.

 

[nickg]

Enough for the Carbon? I thought more flow through the Carbon would be better..

If together, I flow the GFO first, so I can regulate the top 10% to 20% to insure it tumbles....the fines will also get caught up in the Rox carbon I use that is rinsed well....

 

[nickg]

OK so now we start a nice debate.

Pros for GFO first
Control for GFO
Carbon filters escaping GFO

Easy answer.....two separate reactors.

best answer, lol.....

however, dual BRS reactors & others are convenient.........It's more important to regulate the tumbling action of gfo, as carbon should not be tumbled. ROX carbon also releases little, fyi...

Agreed.

I have a dual chamber BRS. I think I will hook it up to start with..

Carbon releases phosphates, gfo adsorbed phosphates. Therefore, carbon first.

+1

 

[jimmystephens]

+1 gfo first.

<u>The tandem reactors are used for a reason. Best practice always dictates the carbon stage is the safety net for most anything gone arwy.</u>
What ever it takes to get a good tumble with the least effort. Anything released from the carbon will be gfo absorbed soon enough. It works best with the tumble first in line. I have de-nitrate biopellets, gfo, carbon in-tandem(including a gravity feed to my basement). Though, tandem can be a pain for a maintenance and stable operational reasons.

exactly! If you use a very high quality carbon, such as

As you can see, there are many ways you can accomplish the same goal. I believe neither are incorrect, try whatever way best suits yourself.

Go with a BRS dual reactor and since they come with foam pads to hold the carbon in place so it doesn't tumble at all it shouldn't matter which one is first or second as long as the GFO is tumbling and the foam pads are in place to keep the carbon from tumbling.

If you're using a high quality carbon then it should release such small amounts of phosphates that it really shouldn't matter whether is 1st or 2nd IMO.
