Clarifier
Overview
A Clarifier is a sedimentation unit designed to separate suspended solids, biological sludge, and flocculated particles from water or wastewater through gravity settling. Clarifiers are widely used in ETP, STP, WTP, CETP, and industrial process plants for efficient solid-liquid separation and production of clear overflow water.
Vikas Engineering designs and manufactures clarifiers in various configurations such as Circular Clarifiers, Rectangular Clarifiers, Primary Clarifiers, Secondary Clarifiers, Lamella Clarifiers, and Tube Settler Clarifiers.
Treatment Process Flow
Wastewater Inlet → Floc Formation → Gravity Settling → Clarified Water Overflow → Sludge Collection → Sludge Removal
Types of Clarifiers
Type | Application |
Primary Clarifier | Removal of settleable solids from raw wastewater |
Secondary Clarifier | Separation of biological sludge after aeration |
Circular Clarifier | Most common for STP & ETP applications |
Rectangular Clarifier | Large flow treatment systems |
Lamella Clarifier | Compact high-rate clarification |
Tube Settler Clarifier | Enhanced settling efficiency |
Hopper Bottom Clarifier | Sludge concentration applications |
