IFR-6000 Series

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.

The IFR-6000 Series water treatment facility close-up shows blue tiled tanks with serrated metal skimmers or weirs used for filtering impurities from the water.

Benefits

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

Navigate Within Tube Settlers & Lamella

Module Features

Stiffening Ribs

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

NSF Certified

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

Trapezoidal Flutes

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

Wave Sheets

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

Featured Installations

Okatie, South Carolina

Application

The Beaufort-Jasper Water & Sewer Authority required a dual solution for particle settling and sludge removal. Brentwood was able to offer its tube settlers for increased settling capacity and the SedVac system to remove sludge from the basin floor upon settlement. Together, the two systems maximize performance through efficient sludge management.

Saskatoon, Saskatchewan

Application

The Saskatoon project, one of Brentwood’s largest tube settler installations to date, posed an interesting challenge. Being located in northern Canada, there was concern regarding the impact the water temperature might have on the performance of the tube settlers, seeing as it enters the plant barely above freezing. A successful study was completed in 2012 and demonstrated performance consistent with standard installations. This resulted in the plant converting its four large basins to Brentwood tube settlers.
