Highly aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the surface of the thickener to form froth. This froth causes issues such as the loss of product to thickener overflow (on product thickeners) and can cause reduction in thickener underflow density due to poor flocculation.
PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the process.

thickener in a peripheral launder. The conventional thickener relies on the settling velocity of the particles, due to gravity, being greater than the upward velocity of water being displaced to the overflow launder. The conventional thickener can be used with or
The overflow weir that surrounds the tank ensures that the flow that leaves the thickener is distributed evenly in terms of m3/hr/m weir length. During the first year or so differential settling of the tank foundations may cause an uneven distribution so that the entire flow passes over the lower part of the weir which results in high
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).
It is critical to introduce the incoming thickener feed in an even and concentric manner in order to overcome short circuiting of fine unsettled solids into the overflow launder. In the past, uneven distribution and the related short circuiting of unsettled solids were overcome by adding more polymer or providing larger sedimentation vessels.
The water meanwhile flows over the edge of the tank and into an overflow before exiting at the side via a pipe. This is pumped away and reintroduced to the wash plant process. The silt eventually exits the tank at the centre point underneath and is pumped away. What pumps would you use in conjunction with a thickener
The overflow from the tailings thickener is sent to the water reclaim pond and then recycled back into the process. Tailings. Download the Tailings Flow Sheets. Oil Sands Open Pit Oil Sands. Oil sands, tar sands or, more technically, bituminous sands, are a type of unconventional petroleum deposit. Oil and tar sands represent a vast wealth of

Sedimentation thickening uses polymers to agglomerate fine particles, increase the solids settling rate and reduce the size of slurry ponds by immediately returning 75%-80% of the process water as thickener overflow to the wash plant. Thickeners, however, cannot totally eliminate the need for slurry ponds. The liquid phase, thickened underflow

from entering the effluent launder. Launder— Inboard, outboard, or radial laun-ders available for effluent collection. Weirs — A V–notch adjustable weir will be de-signed to ensure steady overflow rates, even in windy conditions. FRP, stainless steel, and other materials can be used for weir construction.
to the thickener overflow launder) or on venturi-style induction of superna tant liquor into the mixing area, which is induced by the velocity of the incoming slurry past one or more angled nozzles.
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were
Thickeners Monroe Environmental Circular Thickeners are a crucial step between upstream process clarifiers/separators and downstream de-watering and sludge conditioning processes. A well designed thickener provides storage and equalization, and reduces the costs associated with de-watering.
An overflow launder for a separation cell where particles are fluidiZEd and rise to the top of the cell, has a primary trough ( 1 ) surrounding the rim of the cell ( 2 ), and an array of secondary troughs ( 4 ) extending across the fluid surface from the side ( 5 ) of the rim to the opposite side ( 6 ). FluidiZed particles can report directly to the secondary troughs ( 4 ) without travelling
