WebThere is a long history of innovations in thickener design to enable the production of higher densities. Large High Density thickeners were pioneered in the late 1980s. The roots of Deep Cone thickeners go back to the 1960s. Over the last two decades significant advances in the design of thickeners has enabled production of 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!

WebThe surface loading rate (surface settling rate) is hydraulic loading - the amount of biosolids applied per square foot of gravity thickener: Example: A 70-foot-diameter gravity thickener receives 32,000 gallons per day of biosolids. What is the surface loading in gallons per square foot per day? 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.
