High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and …
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. ... This problem is solved by incorporating a scum baffle that retains the scum layer so that a special ...
These thickeners differ in the way they are built. Some examples of basic differences are: • Bridge supported • Center column supported • Traction drive The feed stream is brought to the center of the thickener in a pipe or open launder and enters the feed well, which is designed to minimise turbulence resulting from the.

Feed, overflow, and underflow systems capable of handling additional material when other thickeners are out of service. Feed and underflow material settling characteristics that may require special rake construction …
Conventional Gravity Thickener Overview. WesTech's complete line of high rate, heavy duty thickeners offers the most advanced designs for use in the industry. WesTech equipment is engineered and manufactured to the highest standard in quality. It offers the precision and durability required to keep your process going.
of a "High Rate Thickener" as one using floc is now commonly being described as a "Conventional Thickener". Altering the flocculants dosage (and/or type) often affects the settling rate by changing the size and/or electrostatic charge. Thus, using more flocculants can accommodate a higher rise rate; however, there is both an operation
The pilot-scale thickener facility used in this study is a closed loop system and is shown schematically in Fig. 1.A sample of slurry is mixed continuously in a 4.5 m 3 mixing tank, and pumped out of the mixing tank underflow into the pilot thickener. The thickener tank is a 2 m diameter by 2 m high side wall tank with a 14° floor and a small discharge hopper (45° slope).
Consider the WesTech conventional segmented blade for superior clarifier operation in a conventional clarifier. ... The wall-mounted baffle is low in cost and requires no maintenance. ... (EDI): Converts the high energy feed from the center column into a lower velocity flow that is gently mixed in an impinged or tangential flow into the ...
Table of Contents At start-up, the relatively high level of feed solids, 17-20%, called for in design led to difficulties in achieving the degree of flocculation necessary to meet required settling rates. It was recognized that decreasing feed solids would improve thickener performance while reducing flocculant consumption (Figure 2). This was accomplished by …
The Conventional Thickener Solid Liquid Separation The Conventional Thickener Click on the thumbnail to maximize the image: Description The bridge type; This layer finds its way into the overflow launder and contaminates the clear overflowing liquid with fines This problem is solved by incorporating a scum baffle that retains the scum layer so that a special rotating scum …
This led to the development of the continuous thickener in its present day configuration in 1905. The use of continuous thickeners rapidly expanded to the chemical, sanitary and water treatment industries. Thickener Operation. During thickener operation, feed enters the feedwell, via a feed pipe or open launder.
Aptamil Feed Thickener can be used to thicken standard infant formula products, or specialty formulas. If an infant is on standard formula and requires a thickened feed, Aptamil Gold+ Reflux Infant formula, which already contains a thickener, is recommended. How to use Aptamil Feed Thickener – Learn More. Reminder:
The Conventional Thickener. Description. Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are …
In Lamellas and other types of thickeners, the feed wells can be an adjacent tank, a rectangular channel adjacent to the operating elements, a launder, a feed box, or an …
A thickener consists of a circular tank with a gradually sloping cone-shaped bottom with a discharge in the center. A slow-moving rake mechanism forces settling solids to the center …

A central slurry feed launder with a feed connection. Two plate pack compartments with overflow launders that straddle the feed launder. Each stack consists of a set of plates at an inclination of 45-60 degrees and a clearance of 5-10 cm depending on the volume and sliding characteristics of the settling sludge as it enters hindrance.
The 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. …
Laboratory settling tests on the feed to the decantation thickeners have shown that sulphates—whether added in solid form, as, for example, (NH4)2SO4, or present in the barren solution, as CaSO4—increase the free settling rate about 25 per cent over that obtained with water made alkaline with lime.
True to the spirit of our organization, our cost-effective designs deliver both innovative and conventional approaches. Our scope of supply includes not only a large variety of clarifier types, sizes and configurations, but complete turnkey support and project oversight. ... • Center Drive & Feed • Kraus-Fall Peripheral Feed • CLAR-I ...
Conventional practice is to add flocculant as a dilute solution to the feed slurry in a launder or feed pipe, possibly using staged addition so as to improve the floc growth. ... Flocculant use was comparable in most cases to …
The overflow launder at the tank periphery receives water recovered from the pulp and evacuates it slowly to avoid dragging fine particles. ... In a Conventional Thickener the feedwell is located in the upper part of the tank. ... The only source of solids in the thickener is the feed and, since no solid passes to the overflow, the solid flux ...
One sample consisted of the thickener feed slurry (nominal − 1.2 mm) and the other consisted of the thickener underflow slurry. A third sample was prepared by ...
It is critical to introduce the incoming thickener feed in an even and concentric manner in order to overcome short circuiting of fine unsettled solids into the overflow launder. ... Conventional Applications. Many thickeners suffer from short circuiting and high flocculant consumption because of poor feedwell design, as shown in Figure 1 below
Froth booms, bridge sprays and launder froth baffle . This is used for low froth applications designed to mobilize froth on the thickener surface. Best suited to pumped feed and where the feed pipe is not laundering. Level 2. Froth booms, bridge sprays, launder froth …
