Beginners guide to thickeners

Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...

Thickening | Sludge Processing

Thickening. Thickening processes are those which concentrate the sludge by removing part of the free water, i.e. the water not associated with the sludge particles or flocs. In doing so, the finished product retains the liquid, free-flowing characteristics of the feed sludge, so that it can still be conveyed by pumping.

Gyral enhancement | Radiology Reference Article | Radiopaedia

Gyral enhancement, also known as gyriform, cortical, or grey matter enhancement, is a pattern of contrast enhancement in the superficial brain parenchyma that conforms to the serpentine morphology of the cerebral gyri. It should be distinguished from leptomeningeal enhancement, which is also serpentine but occurs on the brain …

Watery Tomato Pasta Sauce? How To Thicken

You can thicken watery tomato pasta sauce by either adding more tomatoes/tomato paste or by reducing it further over low heat (to evaporate some of the water). If you don't mind altering the taste and texture, you could add a thickening agent (like tapioca/corn starch) instead. Of course, it always helps to understand why your …

Tailings solutions: How to filter down the options

There are four main filtration options for dewatering tailings after thickening but prior to disposal: vacuum filters, centrifuges, belt presses, and filter presses. For every solution, it is recommended the filter feed slurry be thickened prior to filtration as this can substantially reduce capital and operating costs of the filtration operation.

Sludge Dewatering and Thickening

Sludge can be thickened to 8-10% total solids. A pump then sends the sludge to the anaerobic digester. At the top of the basin is the scum collector and discharge. A gravity thickener uses gravitational forces to separate water from sludge and is mainly used on primary sludge at plants still using this technology.
