• Mechanical dewatering processes, including centrifugal filter presses, vacuum-assisted dewatering beds, belt filter presses, and plate-and-frame filter presses. Mechanical dewatering techniques can require a large capital and operating investment and therefore may only be an option for larger systems.
· Modern dewatering technologies demanded for fine iron ore applications. The large quantities of low grade iron ore around the world are forcing the industry to upgrade for the steel producers. This requires more benefication and there is a tendency towards finer grinding. Thus reliable dewatering solutions are demanded, but at the same time ...
Cases of high level iron bacteria contamination in water bores have increased rapidly in Australia over recent years. These iron bacteria produce thread-like slimes which, together with ferric iron, form a voluminous mass which causes major problems in bores, bore casing, screens and/or the aquifer itself. This may result in: Blockages in reticulation systems Burn-out […]
The dewatering technology of filter press is a relatively mature dehydration technology, which is widely used in the dehydration of many fine tailings at home and abroad.

Dewatering through filtration separates liquids from solids by introducing a medium through which only the liquid can pass. Water and other liquids are removed from the slurry, draining out through a permeable barrier or filter media, and leave a trapped cake of drier solids that are too large to pass through the barrier or filter media.
