Thickenervs. Clarifier: What's the Difference? | McLanahan

Simply put,Thickenersfocus on the settled solids, and clarifiers focus on the clear overflow liquor — the name given to a solution free of suspended solids. Clarifiers. A clarifier will typically treat a low-density slurry of less than 5% weight per weight solids with a focus on producing a clear liquid with suspended solids of less than 100 parts per million (ppm).

Sep 01, 2009· Most tailingsthickenersutilise an automatic flocculent dosing system that takes samples of feedwell water and carries out an automatic jar settling test. This is so important where multiplecoal/ore types are processed through the plant because of different settlingratesand characteristics.

Inhigh rate thickener(HRT) designs the riserateor solids loading will dictate the required tank diameter for any given throughput. Inhighcompression (HCT) and paste (PT) applications the bed depth or the mass of solids in thethickenermust also be selected to ensure the desired underflow density from thethickeneris achieved.

Description. TheHigh-Rate thickenersbecame popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previouslyThickenersare a major component in a plant layout and occupy large spaces which may be saved by introducinghigh-ratemachines. Furthermore, they are normally positioned far away from the center of the plant so to allow ...
