Large ,slurry, separation plants are needed on the surface for this process, which separate the dirt from the ,slurry, so it can be recycled back into the tunnel. While the use of TBMs relieves the need for large numbers of workers at high pressures, a caisson system is sometimes formed at the cutting head for ,slurry shield, TBMs.

Slurry Shield, TBMs are used when the ground conditions are granular with very high water pressure. Hydrostatic pressure is applied on the excavation by filling the cutter head with pressurized ,slurry,, which is also used as a transporting medium when mixed with the excavated material before it is pumped to the cutter head back and, then to a separation plant outside the tunnel.

Wastewater treatment - Sludge treatment and disposal ...

The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage, sludge, is the solid,, semisolid,, or, slurry residual, material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical precipitation, ...

Sludge is, a semi-solid slurry that can be produced from a range of industrial processes,, from water treatment, wastewater treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment , [1] as sewage sludge from wastewater treatment processes [2] : 23–25 or as fecal sludge from pit latrines and septic tanks .

That is why a combi¬nation of EPB and ,slurry shield, is used only if specific project conditions justify these great efforts. The special case of the TBM Variable Density® A ,Multi-mode TBM, with EPB and ,slurry,-supported mode is the most complex form of a convertible machine so its use is only cost effective in very special cases.
