Manual Of High Rate Thickeners

Sustained periods of high inflow rate reduce the retention time and the arrestors ability to separate contaminants or reduce temperature. Short periods of excessive flow can flush some of the retained contaminants from the arrestor to sewer. Poor aeration of wastewater promotes anaerobic decay of retained contaminants, leading to

concentrations that will be achieved by gravity thickening. Overflow Rate Another important consideration is the overflow rate. Overflow rates between 380 and 760 gpdsq ft are typically used for primary solids. Overflow rates in the 100 to 200 gpdsq ft range are used for thickening secondary solids. A high overflow rate can result

Jun 13, 2017 By controlling flocculation and solids inventory, the thickening process is stabilized and consistent, optimum underflow density can be achieved through manual optimization. Flocculant dosing. Flocculant dosing should be matched to the mass flow to the thickener with the rate adjusted to suit the ore being processed.

High Rate Thickeners Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners.

Gravity thickener designs usually include circular tanks, 3-4 m 10-13 ft deep and up to 25 m 82 ft in diameter. The dimensions are based on prediction of settling due to gravity alone. To assist solids transport, gravity thickener bottoms are constructed with a floor slope between 16 and 13.

Biosolids Technology Fact Sheet Gravity Thickening

High-Rate Thickeners, or Clarifiers, recover immediately reusable process water for mineral and aggregate producers, as well as environmental contractors. Thickeners are beneficial in a variety of applications, including areas where water is in short supply or very expensive, re-circulated water is not suitable for reuse in a plant, ponds are located on minable reserves, or ponds must be ...

Sep 10, 2015 On the one hand, if the underflow rate is too low, it is possible to make the thickener overloaded and the mineral particle loss when the mud bed level is high enough. On the other hand, if the underflow rate is too high, thickeners will be short-circuited when the mud bed is pumped out and the feed is directly discharged.

An intelligent control strategy for thickening process

The advantages of DAF clarifiers are their ability to treat a wide range of suspended solids in water at a high rate of solids removal and for wastewater sludge thickening. Millions of micron sized air bubbles in the DAF thickener float solids to the tank surface, forming a concentrated sludge blanket. A scoop removes the thickened sludge.

High Density Thickened Tailings HDTT Storage

This is normally achieved by using compression or high rate thickeners or a combination of thickeners and filter presses. High Density Thickened Tailings HDTT are defined as tailings that have been significantly dewatered to a point where they will form a homogeneous non-segregated mass when deposited from the end of a pipe Welch 2003.

Conventional Thickeners Solid Liquid Separation

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away. Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters ...

limiting flux,a rising sludge blanket thicken-ing failure is encountered. Most design engineers prefer to keep the maximum solids loading rate in the range of 25 to 35 lbdft2.Higher rates ofup to 50 lbdft2have been encountered in plants with low SVIs,well-designed clarifiers,and effec-tive solids removal.The state point analysis

thickening operations are carried out. Actually, the thickening of the sludge is a concern to the operator where he desires a high underflow solids concentration. So it is the general practice to design these processes for both thickening and clarification performance.
