Sulphar Ad plant

[farmer1989]

Hi been looking at biolectric 50kw slurry only ad plant 1 problem the water we pump to the cows is 900mg of sulphar and alo high in iron this means it would destroy an ad plant if we put 1 in any good advice on removing sulphar and ideas on price

Treat sulphur as H2S by running the digester at about 0.5% oxygen. If you are gas mixing, bleed air in through the gas mixer, otherwise a small air pump (fish pond type possibly) to feed the gas space above the digester. You will need to monitor oxygen % as well as H2S and methane levels, but you will need to do this anyway to monitor the digestion.

So instead of removing sulphar from the water I should remove it from the gas ?

That's where it will end up. You want to keep it in the digestate as fertiliser

good point sounds simple to me add a bit of oxygen to remove the sulphar need to ask the manufacturer why they cant just do that
