Get PriceGravity thickeners consist of a circular tank usually with a conical bottom that is fitted with collectors or scrapers at the bottom Primary andor secondary solids are fed into the tank through a center well which releases the solids at a low velocity near the surface of the tank
Get PriceThe compression regime is not well studied and since it normally operates only at the very bottom cone of the thickener it goes beyond conventional design requirements Theory of batch flux The development of the technique began with Kynch who modeled the settling of particles in water
Get PriceMany thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow
Get PriceWith the aid of polyelectrolytes coagulant sludge can be thickened to concentrations in the range 2–6 wv solids The polyelectrolyte dose can be in the range 01–1 gkg of dry solids and the dose should be applied proportional to the feed solids concentration and flow It should be well mixed using an inline static mixer or similar
Get PriceFlocculants are used in gravity thickeners to improve the natural settling properties of solid particles present in the thickener feed slurry
Get PriceThe feedwell performance in gravity thickeners and clarifiers relies on the efficient mixing between solid particles and flocculant to achieve effective flocculation as well as energy dissipation of the incoming feed stream A population balancecomputational fluid
Get PriceA circular thickener comprises a relatively shallow opentop cylindrical tank with either a flat bottom or a bottom shaped in the form of an inverted cone see Figures 12 and 13 The feed mixture is gently and continuously introduced to the feedwell in which exists a pool of settling suspension along with any additional coagulant or flocculant
Get PriceClarifiers and thickeners are essentially ide ntical units a clarifier produces clean water while a thickener concentrates a solids slurry as the desired product In this discussion thickener will be used to describe both units Also a gravity separation of solids from water is assumed to take place
Get PriceGravity belt thickener model selection is a function of hydraulic feed rate the Model G25 thickening system is generally appropriate for 05 to 10 waste activated sludge feed rates up to 125 GPM 79 literssec or 28 M3h and the GSC and GSCE series machines are appropriate for higher feed rates
Get PriceMar 02 2014 · The standard feed well for conventional thickeners is designed for a maximum nominal flow velocity of 15 mmin High turbidity caused by the depth of the feed well When overflow clarity is important or the solids gravity is close to the liquid specific gravity deep feed

Get Pricethickener feed externally Thickener feed dilution is an important facet of good thickener feed system design It can have a significant impact as to whether a thickener achieves its process performance targets as well as the overall cost of operation 40 YEARS OF ANODE CASTING Outotec is celebrating 40 years in the anode casting industry
Get PriceJan 26 2015 · The most common solidsliquid SL unit operation is thickening A wide variety of thickeners are used including conventional deep well paste high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low solids waters
Get PriceThe Difference Between a Clarifier and a Thickener is subtle as they will visually look the same Fundamentally thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids Thickeners are used to concentrate solids while clarifiers are used to purify liquids A thickener will give you a high density underflow while a clarifier will not The
Get PriceGravity thickeners are more functional on primary solids than secondary Mechanical thickening is usually done with either a rotary drum gravity belt DAF or centrifuge but a good three belt press can dual function as a thickening device by utilizing the gravity deck portion of
Get Price2 GRAVITY THICKENING 21 General description of the unit The gravity thickening design is similar to a clarifier Thickeners are usually circularshaped the feed is carried out through a pipe to a central hood serving as distribution and still area with a height that has no
Get PriceApr 02 2020 · Gravity Sedimentation Thickeners And Clarifiers a concentrated slurry is mixed with a solution containing fewer solubles than the liquor in the slurry and then is fed to the thickener As the solids settle they are removed and sent to the next stage referred to as a siphon feed system The feed enters the central feed well through
