HRSCC (HIGH RATE SOLID CONTACT CLARIFIER)
We are manufacturing world class Solid Contact Clarifiers 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.
