High rate thickener design calculations
In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the … See more The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake … See more Rake torque is the most fundamental instrument and an accurate indicator of when things have already gone really wrong! Under normal … See more Bed mass is utilized to control thickener inventory. Bed mass is generally measured by a pressure transducers mounted at the bottom of the tank (figure 4). These pressure transducers’ are best located in the cone or close to … See more Bed level is a frequently installed instrument and can be installed and serviced during normal thickener operation.

WebJun 18, 2024 · A common variant on the gravity thickener design is the picket fence thickener. This technology is fitted with a stirrer comprising a series of relatively closely-spaced vertical arms, and is therefore similar in appearance to a picket fence. For both designs, the sludge enters the centre of a cylindrical tank and flows out to the periphery. WebThe main key to remember with thickening calculations is that solids remain constant.
