Clarifiers work on the operating principles of gravity and particle interactions, with solids settling downwards and liquids rising to the top as they separate. The purpose of the clarifier focuses on maximising the settling of solids for removal in the underflow, and minimising any escape of solids in the overflow stream to provide cleaner ...
averaged flow velocity vectors inside the feedwell for both water and 6%w/w solids. It can be seen that there is an up-flow along the entire central shaft of the feedwell with a down-flow close to the feedwell wall. This gives rise to recirculation regions both above and below the shelf. For the same inlet
The Ovivo ® sludge thickener is designed to continuously produce as thick a sludge as possible from streams of sludge previously formed and collected in separate settling basins. Included with the thickener mechanism are Ovivo's durable heavy-duty drives. The drive is designed to handle the specified torque for 20 years of continuous operation, but we have seen drives still in operation after ...

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).
What is claimed is: 1. A system for performing in-situ aggregate size analysis in a feedwell assembly comprising: a feedwell assembly, which receives an influent feed stream from at least one feed pipe; at least one flocculant feed pipe within the feed stream and/or feedwell assembly, which delivers a flocculant to the feed stream; an in-situ device, which provides images of flocculated ...

This filtering technique works based on spectral analysis of gravity amplitude changes in spatial where the result is a cutoff wave number of 1.1736 x 10-3/meter and a wavelength of 5373.45 m.
Gravity filters are commonly used in applications where liquid-solids separation is required in a variety of different applications for finish water treatment. Gravity filters can incorporate various types of media such as sand, anthracite, greensand and GAC to meet each plant's water treatment needs.

Apr 21, 1995· The incoming slurry or pulp passes through a feed pipe or launder into the upper part of this central feedwell and is introduced into the surrounding liquid through the bottom of the feedwell in a manner designed to create a minimum of turbulence. This makes it possible to contain the bulk of the solids near the center of the unit.
