Moving organic sludge

    Can anyone tell me if organic sludge (with the consistency of thick slurry) can be moved using an auger (I need to raise it a 20-30 degree incline). If so, where can such augers be purchased? Second hand, preferably.

    Sludge from a waste water treatment plant? Assuming you're talking about 16 to 18% solids sludge cake, then yes you can. Sludge which hasn't been dewatered will be closer to 3% solids and will not travel reliably in a screw conveyor at 20-30 degrees incline.

    Thank you for the response. The sludge in question is de-watered, so it should work.

    Is that water treatment plant sludge you are looking to move?

    Yes. Dewatered to about 16% solid.

    Are you intending to use it as a fertilizer?

    Yes. Need to store it in a shed. Thus the need to move it.

    As far as I am aware that sludge contains alumina and should not be desposed of by spreading on land, due to run off and contaminating water courses. Irelands water treatment centres are afaik the only ones in Europe not disposing of this sludge in a responsible manner.

    Depends on what the OP is using as a flocculant and what regulations exist for disposal of sludge if Aluminium Sulphate has been used in the treatment process. I would guess that a good few Irish wastewater treatment plants are sending their sludge to landfill rather than go through the regulatory nightmare of landspreading.

    It is illegal to landspread water treatment sludges on land due to the high level of aluminium in it. All alumium sulphate based sludges will have a high level. There are a number of good env. options for this material however including; use in manufacture of cement, composting (blended with other materials), and use in quarry remediation...which is essentially an inert landfill but preferable to using normal landfill space.

    Most of the co. councils landfill this sludge (in normal co.co landfills) because it is an easy option for them that they have been doing for years, but the progressive guys are happy to look at the alternative options.

    I work for a waste mgt. company that provide sludge mgt. services for this and other sludge wastes (and biological wastes) and would be happy to look at the options for anyone (obviously location is key).
