How Does Gravity Thickening Of Sludge Work

A large amount of mud and sludge will be produced in sand making and sand washing factory. If it is not treated in time, it will pollute the environment. It is necessary to use the thickner to treat the sludge and sewage from sand washing. How does gravity thickening of sludge work?

LDHB independently developed the high-efficiency thickener, which is based on the traditional vertical flow sedimentation equipment, improves the structure of the internal feeding barrel, greatly improves the sedimentation efficiency. The tank body is round, the suspended solids settle into the conical sludge hopper at the bottom of the tank under the action of gravity, and the clear water is discharged from the overflow weir around the upper end of the tank. The overflow port is equipped with scum filter and baffle to ensure the effluent quality. The underflow concentration can reach 70%, and the treatment capacity is 3-8 times higher than that of the traditional concentrator.

Based on the traditional vertical flow sedimentation equipment, LDHB S-series thickener has improved the structure of the internal feeding barrel, which greatly improves the sedimentation efficiency. The plane of the tank is round, the suspended solids settle into the conical sludge hopper at the bottom of the tank under the action of gravity, and the clarified water is discharged from the overflow weir around the upper end of the tank. The overflow port is equipped with scum filtering device and baffle to ensure the effluent quality.

It is a solid-liquid separation equipment based on gravity sedimentation. When working, the solid particles suspended in the pulp in the concentrator vertebral body settle under gravity, and the upper part becomes clear water, so that the solid and liquid can be separated. The slurry wastewater with solid content of 2% ~ 15% can be raised to slurry with concentration of 60% ~ 70% by gravity sedimentation, and the upper part of the tank can realize clear water overflow, so as to achieve the purpose of sewage purification and solid-liquid separation.

Gravity sludge thickener features

  1. Due to the slender tank, flocculant is added in the concentration process, which accelerates the concentration process of material sedimentation and overflow water clarification.
  2. It adopts the working principle of suspension filtration, medium adsorption and precipitation, without purification membrane and vulnerable parts.
  3. The tank body is made of high-quality carbon steel (or stainless steel, epoxy glass fiber reinforced plastic, etc.) with good strength and corrosion resistance.
  4. It has the advantages of low cost, large capacity, high efficiency and stable performance.
