Choosing used clarifiers from IPP helps companies cut costs, avoid project delays, and maintain regulatory compliance with proven separation solutions.

Clarifiers are gravity-based separation units designed to remove suspended solids from liquids, either by settling (sedimentation) or flotation. They are critical in both industrial processes and environmental systems, ensuring that clarified liquids meet required purity standards before further processing or discharge.

Primary uses across industries

• In wastewater treatment, clarifiers separate sludge and particulates before final discharge or secondary treatment.
• In chemical manufacturing, clarifiers remove fine solids from process streams to improve product quality.
• In food and beverage processing, they clarify juices, beer, dairy, and other liquids to achieve desired appearance and purity.
• In mining and mineral processing, clarifiers recover valuable process water and manage tailings.
• In power generation, they treat cooling water and boiler feed water to minimize fouling and scaling.

Types of materials processed

• Industrial wastewater streams with suspended solids
• Process liquids containing fine particulate matter
• Food and beverage liquids requiring polishing and clarification
• Mining slurries and tailings requiring solids removal

Common materials of construction

Clarifiers are built for durability, chemical compatibility, and sanitation:

• Stainless steel for food-grade and chemical-resistant applications
• Carbon steel with coatings for industrial wastewater and mining operations
• Concrete or fiberglass basins for very large-scale municipal or industrial applications

Key features of industrial clarifiers

• Gravity separation for efficient, energy-saving solids removal
• Wide range of designs including circular, rectangular, and lamella clarifiers
• Skimmer mechanisms for scum and floating material removal
• Sludge rakes and underflow systems for efficient solids handling
• Modular and customizable designs for easy integration into new or existing systems
