Get reliable separation and save time and money with IPP’s ready-to-ship clarifiers for plant operations

When your operation requires high-capacity liquid-solid separation to improve product quality or wastewater discharge, clarifiers provide essential performance across a wide range of industries. With over 47 years of process equipment expertise, IPP offers immediate access to high-quality used clarifiers sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. 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

Clarifier FAQ

Have questions about Clarifiers or our services? Learn more about our products and why customers choose IPP.

What industries rely most on clarifiers?
Wastewater treatment, chemical production, food and beverage processing, mining, and power generation industries all depend on clarifiers for efficient solid-liquid separation.
How do clarifiers compare to centrifuges?
Clarifiers use gravity-based separation and are better suited for large volumes with lower energy costs, while centrifuges use centrifugal force for faster, more compact separation of finer solids.
What maintenance is required for clarifiers?
Routine inspection and maintenance of skimmers, drive mechanisms, rakes, and sludge pumps are critical to ensure efficient operation and prevent downtime.
What are the benefits of buying used or secondhand process equipment from IPP?
Buying used from IPP saves up to 70% over new equipment, provides immediate availability, supports sustainable business practices, and leverages 47 years of industry expertise.
