What are the advantages of sludge thickener performance and how many thickening methods are available?

The sludge thickener has the advantages of simple structure, low failure rate, compact frame design, reducing the volume of the whole machine and better dehydration effect; In addition, the concentration method is divided into four methods: air flotation concentration, gravity concentration, centrifugal concentration, belt gravity concentration, etc. the following details are introduced.

1、 Performance advantages of sludge thickener

1. The special design of super diameter circular arc dewatering technology is adopted in the transition dehydration area of sludge thickener, which can make the pressure of filter belt increase gradually and effectively prevent mud running. Therefore, the sludge treatment capacity can be greatly improved.

2. The frame is compact design, and the guide roller is installed in S-type, which makes the whole machine volume smaller and the dehydration effect is better.

3. The sludge thickener has simple structure, low failure rate, stable operation, special screen selection and obvious pre dehydration effect.

4. The "virtual roller" device is added to make the pre pressure dehydration more stable and effectively prevent mud running.

5. The electric control system is equipped with perfect interlock protection device to ensure the safety and reliability of the whole machine operation, and effectively prevent the damage caused by the wrong action.

6. The principle of PLC control design is to adjust the sludge feeding and dosing quantity automatically according to the running speed of the main machine, so that the productivity and dehydration rate can reach a good state and basically reach unattended.

2、 The method of thickening sludge thickener

1. Air flotation concentration method

Air flotation concentration is a method to separate solid particles from water by releasing the gas dissolved in water in the form of micro bubbles, and can be attached to sludge solid particles quickly and evenly, so that the density of solid particles is less than water and then floats up.

2. Gravity concentration method

Gravity concentration is to realize sludge concentration by using the relative density difference between solid particles and water in sludge. If gravity concentration method is adopted, the water content can be reduced from 99, 2% - 99 and 6% to 97% - 98%. For sewage treatment plants with primary and secondary sedimentation tanks, the two sludge can be mixed for gravity concentration.

3. Centrifugal concentration

The principle of centrifugal concentration is to concentrate by using different centrifugal forces with different specific gravity of solid and liquid in sludge. It is suitable for biological and chemical sludge of large and medium sized sewage treatment plants.

4. Belt gravity concentration method

Belt gravity concentration is a mechanical concentration method which uses belt gravity concentrator. In operation, it will be affected by macromolecules in sludge, and the humidity is large during operation, so it needs careful operation.
