Considering the high volume of water consumption in various industries and the lack of water resources in the country, reuse of used water through filtration can play an important role in saving the consumption of this vital element. Among the most important manufacturing industries of the country, where the optimal performance of many machines and equipment depends on water, we can mention iron, aluminum, copper mines and sand production factories. Considering the importance of water reuse in these industries, the use of thickener for water purification is a very efficient solution that has come to the aid of manufacturers in the last few years with the advancement of technology.
Now you may have a question, what is a thickner? Thickeners, which are also known as thickener pools, are actually huge ponds filled with water that are capable of separating solid particles from water with the help of centrifugal force and reusing water sources contaminated with particles from machine operation. Instruments are helpful.
Application of thickener in industry
Water is the basis of every industry, and saving and reusing it in all fields of work is important in order to reduce costs and help preserve the environment. Using thickener for water purification is a useful and economical solution that many industries have today. Steel, tile and ceramic industries, paper making, dairy industries, food industries and heavy metals are only limited examples of the uses of this extremely practical tool. Reasonable price, simple operation and easy maintenance are among the features that have made industrial thickener popular and widely used.
One of the biggest consumers of thickener for water purification are sand production factories, the performance of some of their machines, such as the salt sand machine, is completely dependent on water, and the use of thickener in this industry plays a vital role in purifying and reusing water. does

Getting to know how water purification thickener works
The industrial thickener consists of a cylindrical basin filled with water, the contents of which are completely purified with the help of sedimentation or solid separation from the liquid. The working method of the thickener is that after entering the industrial wastewater into the tank and reducing its turbulence, part of the solid water particles are exposed to various forces such as gravity and centrifugal force due to the difference in weight and the movement of the thickener paddles and settle at the bottom of the pond. After the formation of the thick paste (Underflow) in the lower part of the thickener tank, it is time to leave the clear liquid formed on the water, which is called the thickener head or Overflow, which takes place through the channel in the upper part of the pond. In the last stage of the thickener method, the sediments deposited in the end section are sent to the central duct of the thickener with the help of one or more rotating arms and are thus removed. .
Introduction of thickener components
Regardless of the type and size, all water purification thickeners used in different fields of work consist of a series of fixed components, each of which plays a vital role in the purification and filtration process of industrial wastewater. As mentioned earlier, the sand production industry is one of the biggest consumers of the thickener that uses the thickener. This type of water purification thickener is also composed of the same parts as other industrial thickeners, the most important of which are as follows:
The supporting structure or the main body of the thickener (tank)
The main body of the thickener as a support for the thickener structure can be made of concrete or metal, and its size and material selection is made according to the following:
- Expected resistance
- Weather conditions
- The state of the land
- Operating temperature
- cost

Input feed tank (Feed Wee)
The inlet feed tank is one of the most important components of the thickener for water purification, which is responsible for the uniform and undisturbed distribution of the incoming flow into the pond or the thickener tank.
drive protection structure (mechanism protection)
This part is actually the same bridges installed around the thickner structure, which make it easy to access the device. Among the important advantages of using these protective bridges inside the thickener structure, we can mention the transfer of load around the tank, easier use of the lift and access to the drive from both sides.
Drive and wife collection
With the help of this set consisting of drive and electric gearbox, enough power is provided for the movement of the paddles and the settling of solid materials in the lower part of the thickener of the stone crusher. Usually, the thickener drive is of mechanical or hydraulic type and is able to stop or warn if the amount of torque inside the device increases.
Sarriz Thickner (Over Flow)
This part of the thickener system is responsible for transferring the flow of the small head from the inside of the device to the outside, and the water is guided by it through the grooves on the body.
Under Flow
The finer set in the thickener system is used to remove the pulp or the grains settled in the lower part of the machine. The function of the thin thickener is automatic and through the pump.

Let’s know the types of mine thickener!
The industrial thickener as a powerful purifier of all types of wastewater has various types and the choice among them should be made completely according to the field of work and the desired industry. The most important types of thickeners available in the market are as follows:
1. Ordinary thickener
This type of thickener, which is referred to as the simplest type of water purification thickener, consists of a cylindrical basin whose height is much smaller than its diameter. Conventional mine thickener is used more than other thickeners due to its simple structure and operation and low operating costs. The output pulp concentration of this type of thickener is usually between 35 and 50%, which is considered a suitable rate for most industries. In general, normal thickeners are offered in three models: base, bridge and rail by the manufacturers of this field.
The normal sand thickener works in such a way that first, through the sedimentation mechanism and with the help of centrifugal force, solid particles suspended in the effluent are settled at the end of the tank. The clean water comes out of the device through the small grooves at the bottom.
2. Lamella thickener (plate)
In the situation where the wastewater produced by the industry has a large volume, it is recommended to use the thickener lamella device, which has a high capacity for water purification. Also, this type of thickener can be useful in work environments with limited space due to the small space it occupies. Unlike the normal thickener, there is no paddle in the lamella thickener structure and instead it consists of two upper and lower parts, the upper part of which consists of a series of plates with a slope of 45 to 55 degrees, and the lower part is shaped like It is conical or cylindrical.
The working method of lamella thickener (plate) is in such a way that first the effluent enters the device through the vertical ducts located on the sides of the inclined plates, then it is transferred to the space between the plates through slot-like valves. In the next step, solid grains suspended in water settle on the plates and flow into the lower tank. At the end of the process, the water left from the purification process will be free of any solid impurities.
3. Deep conical thickener
Conical thickener with a large depth and a smaller cross-sectional area than other thickeners, has a 50-60% output material concentration. The capacity of this type of thickener is usually 5 to 6 times the capacity of other types of water purification thickeners, and due to the small space it occupies, it is recommended to use it in work environments with a limited area. Since the amount of solid particles in the final output is relatively high due to the upward flow of water in this type of thickener, its use is recommended only for industries with a very high volume of wastewater.
4. High rate thickener (HRT)
The high rate thickener has almost the same performance as the lamella thickener and consists of a large number of inclined plates that accelerate the wastewater treatment process. In situations where high output capacity and limited space occupation are considered by the employer, high rate thickener will be a suitable option.
What are the most important advantages of Tickner?
The use of thickener in manufacturing industries, in addition to making it possible to reuse water resources, has other advantages, and this has caused industrialists to pay special attention to this industrial wastewater treatment tool. Among the most important of these benefits are:
- Reduce water consumption
- Reduce production costs
- Easy installation due to the simple design of the thickener
- Low maintenance cost due to the simplicity of the thickener structure
