Purus dynamic-membrane filtration

Membrane-grade water at industrial throughput.

Purus is Blue Quest’s dynamic-membrane filtration platform: one vessel architecture, five filter elements from 20 µm coarse pre-filtration down to ~10 nm gel-membrane duty. Membrane-grade water quality at industrial throughput and sand-filter economics. Engineered and assembled in Windsor, Brisbane. Try the Filter Builder, or talk to us about a site trial. Performance figures are indicative; site-specific verification on request.

From this, to this.

Before and after shots from an industrial chiller-water installation. The Purus train delivers the clarity you see on the right — same feed, same plant, same operating day.

The technology

Engineered in Brisbane. Built for the toughest water duties.

Blue Quest commercialises the Purus range — a dynamic-membrane filtration platform that delivers membrane-grade water quality at the throughput and operating cost of industrial filtration. Five filter elements share one vessel architecture, so you can dial in the trade-off between flow, removal target and operating economics.

The result is water aimed at demanding microbial and clarity targets, at a footprint and cost that doesn’t compromise. Trialled on real water at sites including CS Energy’s Kogan Creek dam, Evolve Group manufacturing, Terella Brewing and Surf Lakes, with samples analysed by ALS Laboratories.

The platform scales linearly: add vessels for more throughput, swap the element for a different removal target. The same pumps, the same footprint, the same maintenance philosophy.

Fine-filtration barrier

Gel-membrane configuration: ~10 nm size exclusion, with up to 7-log MS2 bacteriophage removal in university laboratory tests. Site-specific verification on request.

Industrial throughput

From high-flow pre-filtration to ultrafine clarification — one vessel, five element options.

Regenerable economics

Backwash-regenerable operation cuts the consumables bill that dominates traditional cartridge OPEX.

Services

Prefer us to run it for you?

Blue Quest now offers chiller water treatment packages for commercial and industrial sites across Queensland: scheduled maintenance, and an optional plug-and-play Purus sidestream service that we install and operate. Chemical supply from Viva Blu.

Package 1

Standard Maintenance

Scheduled visits, water sampling, dosing checks and clear reporting. The simple entry point for most sites.

Package 2

Purus Sidestream Service

A plug-and-play Purus unit draws a sidestream from your circuit, filters it and returns the water. We install and operate it. Backed by a manufacturing chiller trial.
