Used Clarifiers

Overview

Clarifiers are settling tanks used in wastewater recycling to separate suspended solids from water through gravity and flocculation. They serve as primary or secondary treatment units, lowering turbidity and preparing effluent for further processing or discharge. Common designs include circular, rectangular, and inclined-plate clarifiers with scrapers, launders, and sludge hoppers. Select by flow rate, solids loading, available footprint, and automation needs to meet plant capacity and regulatory limits.

FAQ

What should I inspect when buying a used clarifier?

Check tank integrity (no severe corrosion or cracks), condition of scrapers, drive units, bearings, weirs, sludge hoppers, and any linings. Review maintenance records, past chemical exposures, and the condition of motors, gearboxes, and controls.

How is a clarifier shipped and installed on site?

Smaller clarifier units can ship assembled on trailers; larger tanks are modular or field-erected. Plan rigging with a crane or crawler loader for heavy parts, confirm transport permits, and verify foundations and inlet/outlet connections before delivery.

What routine maintenance keeps a clarifier reliable?

Regularly inspect and lubricate bearings and gearboxes, check scraper alignment, clear launders and weirs, monitor sludge levels and removal systems, and test drive motors and control sensors. Follow a preventive schedule and record all service actions.
