Product Description
Sludge thickening or the process of increasing the concentration of solids & decreasing the volume of free water is a prerequisite in waste water treatment plants, both municipal and industrial. Our expertise lies in presenting a wide range of Sludge Thickener that aligns with highest separation requirements of different industrial sectors. The range we offer comes in solid freestanding designs that gives products proven performance, also easing their operational procedure. The sludge thickeners we offer also have slow moving arms and feature vertical pickets that prevents air pockets by breaking the gas bubbles and also leads to proper aggregation of the flakes in the sludge. Excellence in operation coupled with low maintenance makes the range of Sludge Thickener we provide suitable for use in backwash water recovery in different types of water treatment plants. The plants are also engineered to provide filtrate washwater recovery in STPs.

Types of Sludge Thickener:
  • Gravity Thickening: Specially fabricated circular tanks equipped with vertical paddles are used for sludge thickening. A sludge having solids content of almost 8% to 10% or even more can be acquired using this procedure.
  • Dissolved Air Floatation:  In the floatation thickening procedure, solids get detached from water and move in an upward direction. This happens when small air bubbles attach to the suspended solids, lowering the specific gravity of the solids as compared to the specific gravity of water.
  • Centrifugation: Different types of wastewater sludges can be thickened using this procedure. Here, the sedimentation process is boosted with the application of centrifugal force. The process is usually employed for thickening WAS or Waste Activated Sludge.
  • Rotary Drum Thickener: No odour and zero splashing guaranteed when this process is used for sludge thickening. A heavy duty SS structural frame well appended with a proper sludge distribution system, filtering drum & drum washing system, etc., is used for the purpose. The thickening procedure also requires the use of a drum drive system.
Advantages of our Sludge Thickener:
  • Gives good reduction in the sludge volume
  • Hassle free installation, even in existing tanks
  • Delivers good efficiency when it comes to moisture content reduction
  • Provided with a proper scum removal device and an electro-mechanical torque limit switch
  • The walkway is fabricated using A grade steel and similar metals
  • Necessary arrangements provided for removal of accumulated sludge
