Compact treatment, full Purus chemistry.
A plug-and-play 5 m² dynamic-membrane unit at gravity-class power draw. Sized for six-star buildings, HVAC loops, water harvesting, micro-breweries, and side-stream applications. Identical gel chemistry to the rest of the Purus range.

Outright purchase. Service and gel re-supply contracted separately, monthly.
Hardware sold to a financier at full retail; leased to you over 24 months at ~15% finance equivalent. Service and gel re-supply invoiced separately, monthly, by Blue Quest. Removes the CAPEX hurdle for tender-sensitive municipal and industrial customers.
Compact, automated, remote-monitorable. Drops into building services without the footprint or chemical handling of conventional UF.
Catchment-scale potable polishing for remote, rural and regional operations. 6-log pathogen removal chemical-free; 1.8 bar means solar-compatible.
Plug-and-play with existing plant. Removes biological matter and particulates ahead of RO trains, extending downstream membrane life 2-5×.
A short brief gets you indicative sizing, a CAPEX/OPEX comparison, and (if useful) a Water Challenge proposal. Replies typically within one business day from a named senior engineer.
