Reaction clarifiers (also called High Rate Solid Contact clarifier HRSCC or Solid Contact Clarifier or Solid Contact Clarifier or Sludge Blanket Clarifier) are largely used in pre-treatment of raw water.
Paramount Limited makes clarifier mechanism which is suitable for installation either in RCC/ Steel tank. The recommended slope is 1:12 at the bottom of the clarifier tank for efficient removal of sludge. The unit provides mixing, internal recirculation, flocculation, settling, clarification, positive sludge thickening and removal within a single basin. The sludge is scrapped from the bottom of the tank by rotating scrapper arm.
Raw water enters the primary reaction zone through the inlet into the recirculation drum. Coagulating chemicals may be added in the influent pipe near the point of entry into the recirculation drum. Additional treatment chemicals may also be added in this pipe or directly into the reaction well.
In the recirculation drum, initial mixing and reaction take place in the presence of previously formed floc. The chemicals and recirculated sludge are thoroughly mixed with the raw water by large volume turnover accomplished by the turbine. Further mixing and contact take place in the secondary reaction zone within the reaction well cone, where flocculation is carried to completion in the presence of large quantities of recirculating floc and solids. This treatment ensures thorough chemical mixing and complete floc and precipitates development.
The percentage of solids in the slurry pool within the reaction well may be varied by adjustment of the rotational speed of the turbine and by regulation of the depth and concentration of sludge in the bottom. From the bottom of the reaction well, the flocculated water flows outward and upward where the separation of the floc and water takes place in the outer sedimentation zone. The velocity of the upward flowing clarified water continually diminishes as it rises to discharge into the launder system at the water surface.
