Page: Mechanical dehydration
sludge must be conditioned for this (inorganically with lime, organically with polyelectrolytes), as otherwise not enough water is released. The conditioning means which is used depends both on the dehydration equipment and on the sludge in question. Today mainly sieve band and chamber filter presses are used, centrifuges ...

Page: Natural dehydration
means release of water to the subsoil under gravity and evaporation. The sludge which is dehydrated in sludge drying beds or sludge ponds is where possible used agriculturally. Simple operation and low construction and operating costs are advantageous. The disadvantages are difficult processing of the usually ...

Page: Sludge concentration, dehydration and drying
sludge properties vary, dehydration and concentration must be optimised with each sludge. The solids contents given here are also only guideline values. In all concentration and dehydration methods, burnt sludge water is added to the inflow, as it is loaded with org. substances, N ...
