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 ...

Unlevel Buildings | Mainmark

Unlevel buildings are the result of weak ground and/or subsidence. The appearance of internal or external wall cracks, inability to open and close windows and doors, cracked floors and more can all signal an unlevel building. Once a building becomes unlevel, it is important to fix it right away, or risk further damage and potential hazards.

Tailings & Water Management | McLanahan

Settling ponds are large, manmade, relatively calm bodies of water used to store tailings. They allow the suspended solids in a slurry to separate from the liquid. Over time, the suspended solids settle to the bottom of the pond and accumulate there, leaving the water on top relatively free of contaminants so it can be pumped back to the ...

DRAFT Settling Pond Best Practises Guide Part 1 Rationale

The required volume of a settling pond should be 25% (with pre-settling) to 40% of the volume of pay gravels processed with a minimum of 0.6 to 1 m of depth between the water level and the solids build up. This would allow a reasonable safety factor and a pond size suited to the proposed time period between cleaning or abandonment.

Settling Vessel

The simplest treating equipment for removing solids from water is a gravity settling tank or vessel, which may be designed in either a vertical or horizontal configuration. In vertical settling tanks, the solid particles must fall countercurrent to the upward flow of the water. A typical vertical gravity settling vessel is shown in Figure 4.6.
