Mobile slurry separator

[sjt01]

I wouldn't want serious quantities of acids or alkalis on the place. They are a health hazard, never worth the risk. Bad enough having drums of concentrated hypo about.

Knowing you have 10 ibcs of conc sulphuric about does concentrate the mind, and treated with respect and reasonable engineering controls is no real hazard

I'd not want the stuff on the place, not if I had half a dozen staff working. Not everyone is aware of the risks and an IBC is way too readily damaged.

Surely as a dairy farmer you are bound to have handled plenty of drums or ibcs full of alkaline and acid. I never have to go near the stuff.

If someone was coming to separate your slurry and acidify it at the same time you would never even be near it or see it.

What’s the science behind acidifying it? Surely slurry is acidic already hence the need for lime?

Turns the ammonia into ammonium sulphate
More readily available to plants

Reduce ammonium lost from open slurry storage and when slurry is spread, the lost ammonium increases the need to buy in N.

At high pH that slurry and digestate normally are (7-8), the ammonia is just a gas dissolved in the liquid, so easily lost to air. With pH below 6, it will be in the form of ammonium ions, so kept in solution. If using sulphuric it will be ammonium sulphate

If the company were bringing the acid with them and none of my staff were near it or had to handle it, that would be preferable in my view.

What a load of old snake oil and sales cobblers.
Similar to slurry bugs.
spread correctly (not with a splash plate) I fail to see it will make much difference. For the money paid for the acid is it going to be cheaper than the extra unit of N it might provide…?

Second user conc sulphuric is the cheapest sulphur fertiliser you will find, and if it increases nitrogen reaching the soil it is all for the good

It's proven science. In terms of cost. I've been told you don't really save or lose anything financially at current fertiliser costs. It's the reduction in bought in chemical fertiliser and reduction on ammonia emissions from the farm which the industry is going to have to do whether you like it or not that is the big seller.

Made this in Jan 2023
Chinese Seperator (stainless screw and screen) this is the smallest they do) (got given it to test out) (but would of cost about 2.5k with out shipping)

choir sub pump (cost £3400)

110volt conveyor second hand off eBay (£1500)

steel box about £800

pipes and couplings etc £300

£800 to wire up on to a board

completely mobile nothinging fixed

simply Seperating top lagoon to bottom lagoon

genset straight out of the Cummins factory £8k bit over kill at 65kva but intend to rig at least another 3 Seperator’s up to it

roughly 25hrs work putting it all together

output is about 40000gal in about 12hrs and would get a full trailer in 12hrs 20ton ish of solid

feul 2.2ltrs per 1000gal

run off a genset because was worried electric wouldn’t run it and parlour etc at the same time and wanted it mobile aswel


had to modify 2 things at the start
Convert it to 4inch not 3inch (that it come with)
Buy a decent chopper pump instead of the rubbish Chinese pump it come with.

runs like a dream now, just move the trailer once a day, barely have weights on much as it comes out to dry if you do.

doesn’t have to be run everyday, it’ll will drop a 450000 gal lagoon about 6inch in a day

I’ve run it for 12months now when needed, stripped the Seperator in December (20mins) no noticeable wear on the screw or screen

one little niggle is the chopper pump doesn’t like bandages or cow block (plastic ones) but doesn’t happen often tbf but it’s just a lift the pump out with loader screwdriver and job done

The trick is setting the overload on the pump right so it stops and doesn’t f**k the pump motor.

give these firms the middle finger with the rip off prices they quote

If people like facts and figures it costs me 1000ltrs of deisel to do the 450000gal lagoon to the other lagoon. With using a genset you can see the actual usage of electric so doing the conversion it works out roughly £30 if it was all run off the mains (19p a unit)

happy to answer any questions

Sounds extremely slow and expensive on fuel. 2.5ltrs per 1000 gallon, that’s about £1.90 per 1000 gallons, that’s 4.5 m/3.
Our fixed seperator does about 4400 gallon in an hour using two 5kw motors which in my head works out allot cheaper per 1000 gallon…?

This is a baby Seperator probably compared to yours, what is your Seperator and cost to put in etc ? I’m Not clever enough to work out how much electric yours is using but I’m sure someone will be along shortly to tell us. I’ve priced the biggest ones they do and could still buy 4 cheaper than they quote for one over here.its been made as a test to test the quality of the Chinese Seperator’s

but I’ll keep it going I’m over the moon with it

but also 4500gal of what consistency, if it’s like pee you blitz it, we have barely any rain water go in ours

Build another (or more) the same & I’d imagine the cost per cube would drop quite a bit. Can’t imagine the generator is exactly working much.
How much did your fixed one cost to buy & instal? I expect he has quite a bit of money left over to run it.

It’s pretty thick sawdust slurry. To the point if we suck the reception pit out with the tanker when we have a power cut the tanker don’t spread it very well. Comes out the splash plate like cow pats…

price wise it cost us fully installed £37,000, parts wise it’s cost us zero. Only on Friday I looked in the end of it and still showing no signs of wear on the screen or worm inside. Apart from lack of electric last year after a storm for a few days and the farm genny not being man enough to run everything we’ve had one breakdown and that was the pump sucked up a set of cow shackles, hardly the pumps fault. After we figures out what the problem was it took us all of 40 minutes to get it going again.

I thought the point of this thread was mobile slurry Seperator? And I could probably add another 8-10 Seperator’s to this for the same cost of yours if you want a race I could sell the genset for a profit tomorrow if I needed but it was purely setup like this to simply test the Seperator out. Because we see them as disposable Seperator’s at the cost of them. And when possibly 400-500 Seperator’s might being purchased it needs testing well

Mount it all on a chassis with a few separators mounted to drop the solids all in the same place so you only need one conveyor, or maybe on a frame that lifts up with them all discharging to the same side & a fold out tray to push the solids out a bit & stack it up so no need for any conveyors & jobs a good un.
