Purus dynamic-membrane filtration
Membrane purity at sand-filter economics. From 20 µm coarse pre-filtration down to 10 nm gel-membrane virus removal — one vessel, your numbers, your industry.
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.

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 that meets the toughest microbial and clarity targets, at a footprint and cost that doesn’t compromise. Independently validated on real water at sites including CS Energy’s Kogan Creek dam, Evolve Group manufacturing, Terella Brewing and Surf Lakes.
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.
Gel-membrane configuration delivers 6 log microbial reduction — verified on real water.
From high-flow pre-filtration to ultrafine clarification — one vessel, five element options.
Backwash-regenerable operation cuts the consumables bill that dominates traditional cartridge OPEX.
Pick a filter element, set your duty cycle and economics, and see flow, daily output, water quality and the annual return live. Five options, one vessel, your numbers.
