Once there, the digested sludge is dumped into the landfill with all other waste, according to county special waste analyst Larry Gibbs.
The examination of data on digested sludge mixture ALK, VFA and pH showed a reduction in alkalinity in digesters receiving sludge with a max dose of Fe (see Table 4).
For this reason, recent research efforts were concentrated on recovery of heavy metals using different biomaterials, such as waste sludge, digested sludge and waste biomass from commercial bioprocesses (Dean 1977).
Post digested sludge condition has shown that the benefits of simultaneous conditioning and mixing create a digestate that is more consistent and more acceptable for use in agriculture.
The digested sludge 'cake' remaining after the process will be a Class A biosolid - a safe and low-odour product containing no detectable levels of pathogens, such as E-coli, and will be used as a valuable agricultural fertiliser.

Also, the total solids (TS) concentration for the returned activated sludge and aerobic digested sludge was measured to be 0.
It is possible to work with primary sludge, thickened sludge, activated sludge (Baudu 1995, Urrutijetxea 1993) return sludge, digested sludge, sludge water and lime sludge.
Whereas E-11 was isolated only in sludge samples, E-13 was isolated in primary wastewater and in digested sludge, but only in the trickling-filter plant.
