Kelvin Posted February 6 Share Posted February 6 (edited) The reason I ultimately went with the Graf is because the guy that did our groundswork has installed every type available up here in Perthshire. When he built his own house he went with the Graf. He liked the ease of install and he hadn’t heard of any of the number he’s installed ever have a problem. I also like the simple design and the easy access remote blower. All the blower type are relatively simple things though.

But it was supplied as part of my groundworks so had a slight discount. Filpumps also quoted a good price discounted as part of my potable water supply and treatment. I never went with them for the treatment plant though. I’d be happy to recommend them as they did a neat install of my water treatment. I can pass on my contact if you want.

saveasteading Posted February 7 Share Posted February 7 (edited) Looks like the vortex is about £2400 and rhe Marsh £1800. Plus vat. vortex has built in sampling chamber apparently. It's all easy to find online. Edited February 7 by saveasteading Link to comment Share on other sites More sharing options...

Very happy with technical advice (a real person) and the product. UK made, fibreglass. What else do I like? Options for depth to keep the hole shallow. Easy delivery. Bought through your BM so iz on account. Not overcomplicated.. 3 Chambers in a line Mucky in, almost clean out and that will still clean the water and flow in a power cut. I've no experience of the others, so have nothing against them. 1 Link to comment Share on other sites More sharing options...

saveasteading Posted February 7 Share Posted February 7 The prices may vary according to whether they do exactly the right size. I saw these online yesterday but know them to be in the right field. We bought the 10 person for £2,295 +vat, a year ago. 1 Link to comment Share on other sites More sharing options...

dpmiller Posted February 7 Share Posted February 7 check specs carefully- some brands need a costed upgrade to carry out Phosphorus reduction I think, and this is a fairly recent thing. Link to comment Share on other sites More sharing options...

Amateur bob Posted February 7 Author Share Posted February 7 i suppose the question is do most of these other makes have phosphate stripping as standard? Link to comment Share on other sites More sharing options...

I'm not aware this is a requirement. Perhaps is best practice if discharging to a water course as it increases algae. Do you have a source for this info?

saveasteading Posted February 7 Share Posted February 7 (edited) OK from a very quick study. Phosphorous (P) is a problem in rivers and ponds. Package treatment plants reduce P whereas septic tanks don't. The concentration is less important than the amount and timescale. So big plants eg on a housing estate, may need additional treatment. If going to soakaway it is less of an issue. Local authorities in sensitive areas may require additional treatment to reduce P esp on big developments It's an extra tank with chrmical treatment, at a few £k whoever supplier. For a single domestic PTP to soakaway it doesn't seem to be a worry for us. Edited February 7 by saveasteading Link to comment Share on other sites More sharing options...

saveasteading Posted February 7 Share Posted February 7 That's good policy though. Lochs are very low on nutrient so that would really mess things up. If the P tank is £3k then are you going to pump the septic contents to the new, PTP and a single P tank? The next size of PTP isn't usually much more.

The next size of PTP isn't usually much more. the old septic tank will need to come out altogether and a biodisc with phosphate stripping is to be put in place and also the same at the new build so 2 tanks needed which is why im keen on a cheaper make than klargester if possible Link to comment Share on other sites More sharing options...

saveasteading Posted February 8 Share Posted February 8 Can the output of both tanks be piped to a single P treatment installation? I'm wondering if the planners have heard of the klargester phosphate removal equipment and assumed this was a digester too. But no, from klargester or Marsh and perhaps the others , it is an extra thing. Link to comment Share on other sites More sharing options...
