So my question is
biosolids = sewerage solids (yes /no)
biosolids do not equal putrescible waste (yes /no)
This is part of the definition problem. People use the term biosolids to=
cover quite a few situations.
Biosolids are the solid part of human manure after the initial sewage tre=
atment has been performed.
*thanks -looks like I got that bit right
So - how many different ways of doing the initial seawge treatment proces=
s? At least a couple, that I know of, just to begin. Activated charcoal b=
eds, trickling filter beds, anaerobic digestion chambers, aerated ponds - a=
ll different ways of handling sewage.
Each method results in different kinds of processed waste material.
Does the seawge treatment plant separate industrial effluent from residen=
tial seawge? Offices? That is critical. If industrial waste was allowed =
in, don't even think about using those biosolids. The heavy metal problem =
is a killer.
If the biolsolid material is from residential or office areas, then most =
likely it could be processed into good compost.
* u r more trusting than me! - I have seen what the average residential/w=
eekend yobbo puts down the toilet, sump oil, paint *thinner, leftover chemi=
cals u name it - it gets in there - still highly suspect I think!
*Sydney dries the stuff, mixes it with lime, (probably kiln dust) and giv=
es it away to farmers - on a u-haul basis - with strict limits *on the amou=
nt to be applied per acre and nil allowed within the catchment basin for Sy=
dney water - maybe that tells us *something?
So, definitions are required, and we need to use the same words to descri=
be things.
I agree!
