IFR-6000 Series Overview

IFR-6000 series tube settlers are a cost-effective solution for drinking water and wastewater plants to increase treatment capacity, reduce new installation footprints, improve effluent water quality, and decrease operating costs. We utilize our knowledge and experience with the clarification process to provide complete tube settler systems that are custom-engineered for any application.

Our blue tubes are also designed to complement Brentwood’s sludge collection and removal systems, allowing customers to purchase a fully integrated sludge management solution from a consistent, single-source supplier.


  • Increase settling area without increasing footprint

  • Minimize turbidity load on filters

  • Cut coagulant dosages by up to half

  • Integrate with Polychem & SedVac systems for sludge removal

Module Features

Module Features

Sedimentation Rate

Precise Assembly

Engineered for quality, tube settler sheets align to form uniform modules, evenly distributing load for maximum lifespan.

Tube Settler Media

Stiffening Ribs

Formed-in stiffening ribs strengthen flute openings for industry-leading weight-bearing capacity.

NSF Certification

NSF Certified

Modules are certified to NSF/ANSI Standard 61 for drinking water applications.

PVC Tube Settlers

Trapezoidal Flutes

Corrugated sheets forms dual-angle flutes that encourage sediment compaction, allowing even the finest floc to settle.

Sedimentation and Sludge Removal

Wave Sheets

Unique wave sheets align perfectly with corrugations on adjacent tube settler modules to provide even flute spacing and create a nesting effect.
