Thickeners gravity

In gravity thickening, large and relatively fragile floes are needed to aUow high settling rates and fast coUapse in the compression zone. [Pg.389]

Prethickening of filter feeds can be done with a variety of equipment such as gravity thickeners, hydrocyclones, or sedimenting centrifuges. Even cake filters can be designed to limit or completely eliminate cake formation and therefore act as thickening filters and be used in this thickening duty. [Pg.393]

Gravity thickening is appHcable to primary municipal sludges and most chemical sludges. [Pg.194]

It provides better solids-liquid separation than a gravity thickener. [Pg.895]

For many sludges, it yields higher solids concentration than gravity thickener. [Pg.895]

This is a process for concentration of sludge by removing water. Either gravity thickening or dissolved air flotation thickening can be used. The thickening efficiency depends on the nature of sludge to be processed [15]. [Pg.614]
