Apols for a silly question; but what is the purpose of the separation? [aside from emptying the tanks?] is it legislative/regulatory? or is it for the dry material [assume that is spread back in the land? correct?
This has everything to do with Dutch regulation. Farms with (dairy) cows and pigs are limited in the amount of phosphate they can produce. If they have to much manure and not enough land to put the slurry on it has to be processed and exported. The thick manure contains most of the P which is exported to countries such as France where it is used as a valuable fertiliser.
@@gearoidoconnor6900 No problem glad to help out and show how things are done elsewhere in the world. Our system for animal husbandry and fertiliser is a bit different to others!
I can ad some info to what Agrifoto said. The phosphor is mostly bound to particles and end up to a great extent in the solid phase from the saparation. From 100 t manure, you get about 15 t solid phase which contains about 2/3 of the total phosphor while you are left with 85 t of thin liquid with 1/3 of the total phosphor. Since the volume of the "phosphor concentrate" is much smaller, it's easier to transport it far away to areas that want the phosphor and you can spread the liquid on your own fields. The liquid on the other hand contains most of the total nitrogen.
Nice and interesting video. Greets Stefan
Thank you Stefan!

Heuyy langeweg op de kaart!
How much for this machine?
What is the cost per gallon?
Do you use any polymer?
what happens with the liquid thats left over?
This is used as fertiliser.
Ehh das in hoeven bij molenaar!!
