Clarifiers

KWI’s clarifier products range from our solids contact clarifier to our sedilamella. Each product is specialized for specific applications and can be readily incorporated as part of the design process.

The KWI Solids Contact Clarifier

The KWI Solids Contact Clarifier has the ability to act as both an enhanced flocculation device as well as a high rate chemical precipitator. Mixing, internal solids recirculation, gentle flocculation and gravity sedimentation are all combined into a single unit.

Key Features and Benefits

  • Lower chemical and energy consumption

  • Smaller footprint compared to conventional flocculation and sedimentation tanks

  • Lower costs for equipment, civil work and operations

Applications

  • Raw water clarification

  • Lime softening

  • Lime saturator

  • Wastewater clarification

Circular Radial-Flow Clarifiers

KWI offers Circular Radial-Flow Clarifiers whose water flow pattern in the clarifier is radial. In order to achieve the radial flow pattern, the raw water flows into the clarifier from either the center or the periphery.

Key Features and Benefits

  • Mature mechanical sludge discharge technology

  • Reliable operation and easy management

  • Radial-flow clarifier offers good sedimentation, large treatment capacity, and little agitation to the water body. (Effective SS removal)

Applications

  • Primary clarification

  • Secondary clarification

  • Tertiary clarification

  • Raw water clarification

Sedilamella

The KWI Sedilamella are ideal for upgrading existing overload clarifiers, which have no room for further expansion. KWI's solution combines the advantages of a parallel plate separator and a circular clarifier.

Applications

  • Primary clarification

  • Secondary clarification

Key Features and Benefits

  • Increase sedimentation surface, thus increasing system capacity

  • Requires only 60-80% of the area for a traditional sedimentation clarifier

  • Available in a variety of mounting styles

  • Lower capital cost than conventional settlement clarifiers

  • Stainless steel tank delivered in one piece to reduce site construction time

  • Can be supplied with integral flocculation tank & mixer

  • Large solids hopper to increase sludge consistency by competition

Sludge Thickener-KWI DAF

The KWI Dissolved Air Flotation (DAF) can be utilized for Sludge Thickening in municipal or industrial wastewater treatment processes. The sludge concentration can be up to 6% with the KWI air flotation. Sedicell® and Megacell® are specially designed for sludge thickening.
