The Thickener Tank is equipped with a slow moving vertical paddle, like a fence. The sludge is usually pumped continuously from the sedimentation tank to the thickener, and the thickener has a low overflow rate, so that excess water overflows and the sludge solids concentrate at the bottom. The sludge layer is maintained by controlled removal, which can be carried out continuously at a low rate. By this method, sludge having a solid content of 8 to 10% or more can be produced. This means that about 2/4 of the water has been removed when the original sludge content is 2%, and one of the targets for sludge treatment has been achieved.

Gravity thickening involves the use of specially designed round tanks to concentrate fine sludge into more dense sludge products. One limitation of this form of clarified water treatment is that it is primarily an excess sludge sludge activated sludge process. Thickened tanks have vertical blades that move slowly. The sludge flows into the concentration tank and eventually removes excess water from the solids collected at the bottom. Gravity thickeners have a tank-like process, but they have a sloping design that allows solids to collect at the bottom.

In most cases, dewatered sludge usually contains a large amount of water, up to 70%, although it is in a solidified state. Therefore, pre-drying and dewatering of sludge is very important. Although the use of sludge drying beds is the most common method of performing this process, it is very time consuming and can take several weeks to complete. To speed up these processes, waste management plans also use solid-liquid separation devices to perform this process. In fact, centrifugation is becoming one of the best ways to purify sludge.

The choice of sludge treatment method depends on several factors, including characteristics, volume, time, and available processing options. When looking for dehydration services, finding a partner who can provide a full range of services, the right dehydration technology, and the most cost-effective solution for your specific problem is important. Zhejiang Golden Machine Factory is your choice.

The sludge concentration is measured in a variety of ways. Each method depends on the downstream process, the size of the wastewater treatment plant, and the physical limitations associated with it. Thickener Tank is one of them. Gravity thickening involves the use of specially designed round tanks to concentrate fine sludge into more dense sludge products.

A limitation of this form of clarified water treatment is that it is primarily used for excess aqueous sludge from activated sludge processes. Thickened tanks have vertical blades that move slowly. The sludge flows into the concentration tank and eventually removes excess water from the solids collected at the bottom. Gravity thickeners have a tank-like process, but they have a sloping design that allows solids to collect at the bottom.

Typically, it contains biosolids removed from liquid sewage. Sludge concentration is important because it is the process used by wastewater treatment centers to increase solids concentration and reduce free water. This step minimizes the load on the downstream process, such as sludge dewatering and digestion.

In most cases, static concentration is used in organic sludge, such as sewage treatment plant sludge, in the absence of polymer. It may be beneficial to inject lime only when the fermentable sludge remains in the unit for a long period of time (for example, without dehydration on weekends) or in hot areas. The goal is to maintain a pH of 7 to 8 at the bottom of the unit. This requires lime to be added in a proportion of 10% suspended solids to control the deleterious effects of fermentation and odor.

In centralized installations, we often see an “open-air big well” in an open-air environment. This is a high-efficiency Thickener Tank that plays a very important role in the beneficiation process. The mineral processing industry usually refers to it as a Thickener Tank well according to its shape. So what is the principle of a high efficiency Thickener Tank?

The hydraulic center transmission type concentrator of Zhejiang Golden Machinery Factory consists of transmission device, bridge frame, dosing device, feeding pipe, fixed cylinder, cloth drum, scraper, shaft, long raft, short raft, boom, electric control device, hydraulic Station, maintenance hangers and other components. It works in the same way as a traditional concentrator. Under the action of the flocculating agent, the slurry particles in the concentration tank form a cluster structure. When the size of the pellet consisting of ore particles is increased to a certain extent, it will be under its own weight. The precipitate settles to the bottom of the concentrating tank and becomes mucus.

The pregnant liquid is separated from the lean leaching residue in the concentrator filtrate-solids circuit. The decision to use this separation is based on the sum of the economic factors of the pilot plant and the design phase. Although no countercurrent decantation is added during the refining process, the problems addressed in concentrated leach slag and the experience gained in industrial plant operation are related to countercurrent decantation, particularly when applied to slow settling leach slurry. Or when there is a relative slurry.

Valuable, nasty or toxic steam with high vapor pressure. The nickel sulphide concentrate is leached with air and ammonia under pressure to dissolve nickel, copper and cobalt and most of the sulphur, leaving a residue of iron and siliceous material. Part of the ammonia used to recover copper in the subsequent distillation stage is recovered from the solution as a higher sulfide. Nickel is precipitated under hydrogen pressure at a high temperature.

Thickener Tank and fining agents use a slowly rotating jaw arm to separate solid particles. The liquid feed containing suspended solids is fed into a tank having a diameter of 5 to 500 feet. As the particles settle, the inclined jaws move the concentrated slurry toward the center of the tank where it is removed. The clear liquid overflows the top of the tank and is collected in the tank.

There are three main types of thickener tank/clarifiers: bridge supports, column supports and traction. In a bridge-type stent thickener, such as the one shown below, the tweezers and drive mechanism are suspended from a bridge across the diameter of the can. For diameters less than 100 feet in diameter, they are usually economical.

The carrion absorption arrangement is advised to accomplish flocculation with a minimum of big-ticket chemicals. The flocculation catchbasin has borderline inlets and outlets to aerate flocculation by abbreviation agitated shear. This architecture creates a affable boil accepted accumulated with carrion and polymer. This rotational motion aswell increases the absolute carrion abode time for floc development.

The arch clarifier is acclimated for primary carrion treatment. After coursing ample altar and alluvium out of the water, the raw wastewater is beatific to the primary clarifier.


Both thickeners and fining agents are acclimated to abstracted liquids and debris by settling. A apply is acclimated to apply the debris and a fining abettor is acclimated to absolve the liquid.
