Floating cover for slurry store

[MickMoor]

Separators are highly saleable!

I have my doubts about the economy of secondhand tanks. If you are giving it away, the taker will make a saving of 20% at most over new! He will need to have it taken down carefully, all sheets completely cleaned of the old mastic, any damage repaired or the sheet replaced, buy new bolts, nuts and washers, (allow £35.00 per hundred) new anchor bolts and probably clamps, 2.5-3 tubes of Sikaflex mastic per sheet, (£see my wesbite) and find somebody qualified to certify that it has a design life of 20 years, to satisfy the EA. Concrete base costs, erection, any ancillaries that need replacing, pumps, jetter, stirrer, will all be the same as new. If it is new enough to easily meet the life requirement, it will have been built with Sikaflex, and you can take all th ebolts out and it won't fall down; it is easy to damage the glass coating unless you are practiced.
For these reasons, people think I am taking the p**s when I offer an apparently derisory amount for second hand tanks.

I know they are not worth much with the work involved but we've put up a few seconds hand stores never used new bolts

What about these : http://www.hexa-cover.dk/uk

Here in Denmark they are tested to give same reduction in N loss like a "cirkus tent" cover.

You're a hero! I expect you had somebody inside to hold them to stop them spinning when you did them up, or perhaps used a spanner, because it is less likely to spin the bolts even though it's slower, and if you tell me you didn't need to change any because they wouldn't tighten, or because you damaged the head holding it with vise grips, you're lying! Furthermore, the plastic caps on the heads were of a type of plastic that becomes brittle due to the UV rays in sunlight, so the bolts in the top ring and probably some of the second ring should have been replaced to get that 20 year life. Still you know best, it's only my job!

Yes, heard about them, not seen them over here though. There are two conflicting requirements though, are you keeping rainwater out, or keeping nitrates in, or trying to do both?

Think you need to take a chill pill maybe you've been around the stores to long and the gas is affecting you.at no point did I say I didn't change any I said I never bought new ones maybe we have thousands of bolts from other stores.
Glad you think I'm a hero

Much happier if that's the case, but you did say you had never used new bolts! All the regulations and complications we face are the result of cheapskates trying to save the odd penny. The reason the EA are fusy about secondhand stores is because there have been failures, usually put up on the cheap.
There have of course been some expensive failures, (think of a well known educational establishment), but quite often they can be traced back to somebody without knowledge of how these tanks behave.

What's a second hand tank worth good condition think it's 60 foot across 3 sheets high
Sheets are worth a bit to us as will be ideal to put round the pig shed

I'd use the sheets around your pig shed.
