LetMeGrow: Caution! Really Big Kalk Dripper

[Reeferhead]

Check out page three. I visited the site about two months ago. This is an average sized one at 60 feet and 75 ton capacity

They were using lime kiln dust for a while because its cheaper but it kept bridging and clogging the doser. Now they use CaO, pebbled quicklime. At $130 a ton and about a ton a day.

They had a total fish kill last summer when the doser ran out of lime and logistics fell through to refill it.

This is just a quick and relatively cheap fix to a complicated and widespread problem.

Best thread ever.

Don't a lot of lakes have kalk drippers though?

Thank goodness no!

This is a CaO silo was designed to help buffer a heavily impacted acid mine drainage stream. This stream once had pH values as low as 2 killing practically all life. 2006 was the first year this 10 mile stretch of creek has seen fish in about a hundred years. I think this was the first one they built in Ohio. These dosers are very popular in the Appalachian region where streams have heavy flows and are highly acidic from years of unregulated coal mining.

interesting.

It is very interesting !

I probably misspoke.

There is quite a bit of lake lime dosing going on in the North East and Canada however the acid source is mainly acid rain and not acid mine drainage (AMD). They don't have the natural buffering capacity of the limestone bedrock we have here, their bedrock is mostly granite. So, their salmon die and our bass are coolio.

Oh and JxMetal,
I was at a certain LFS after the frag swap and low and behold they still have it written on one of their tanks, "Red Sand Hopper"
I almost &*^%

I saw that same writing there! I almost fell over laughing. I want to see them put another one in there.
