High Rated Solid Contact Clarifiers:

HRSCC- High_Rate_Solid_Contact_Clarifier

We are manufacturing world class Solid Liquid Seperation HRSCC that have capacity to act as both an improved flocculation device and high rate chemical precipitator. Here, mixing, internal solids recirculation, gentle flocculation and gravity sedimentation are all combined within single unit. The solid contact clarifiers mix the influent flow with previously settled solids within the draft tube. In this, the gentle mixing within the reaction well promotes agglomeration of floc particles and chemical precipitates. Then, the aggregated solids settle out more quickly in the clarification area. In the solid contact clarifiers, clarified overflow is removed through a radial launder system that draws water from the complete surface area to avoid solids carryover caused by uneven velocity currents. This Clarifier is a high rate, solid contact, sludge recirculation in minimum space and using a minimum amount of chemicals, produces an effluent of the highest quality. Used for clarification, lime softening, Silica reduction or organics reduction of water & waste waters containing suspended solids, colors and organic impurities. It provides means for chemical addition and mixing, flocculation and up flow clarification in a single unit.
The mechanism would be of centrally driven type with fixed full bridge spanning the tank diameter with necessary walkway and handrails to access drive unit at the centre.

Principles of Operations:Coagulation/Flocculation

  • Colloidal particles and suspended solids brought together by Coagulants
  • Coagulated particles made heavy by flocculants
  • Heavy flocs made to settle down
  • Substantial concentration of previously formed flocs, recycled for ‘Seeding effect’ responsible for speedy flocculation Hydraulic Separation
  • Uses up flow design to move water into settling zone for Clarification.
  • Features:

  • Low energy mixing for chemical reactions & formation of floc particles
  • Unique low shear high volume impeller.
  • Gravity sedimentation clarification and enhanced flocculation in one unit.
  • Consumes less chemical input.
  • Low horsepower requirements.
  • Requires less space than conventional flocculation and sedimentation train.
  • Considerable savings in terms of tank age, civil work, and operational costs.
  • Applications:

  • Clarification of surface water
  • Lime soda softening
  • Removal of colloidal silica
  • Color removal
  • White water recycling
  • Primary (physico-chemical) treatment of waste water
  • Removal of heavy metals in the chemical and automobile industries
