The Purus range

Four Purus sizes. One vessel architecture.

A consistent vessel architecture across four form factors: Purus 20.1 (~20 kL/day, 1 m²), 50.2 (building-scale fixed), 100.5 (~100 m³/day skid) and 100.20 (~3 ML / 30 days, 20-ft container). Same five filter elements and the same maintenance philosophy. Throughput figures shown on this page are for gel-membrane configuration; coarser elements deliver higher flow at the same footprint. Sizing for your duty is part of the engineering conversation. Verification on request.

Range overview

Pick the size. Pick the element. Done.

Throughput and deployment context drive the size choice. Water quality target drives the filter element choice. Across the range the same five filter elements apply, so you can dial flow, removal target and operating economics independently of unit size.

Note on throughput. All throughput figures shown are for gel-membrane configuration — the most demanding water-quality target on the platform. Coarser element selections (3 µm through 20 µm) deliver significantly higher flow at the same vessel footprint. Sizing for your duty is part of the engineering conversation.

Purus 20.1 compact fixed unit
Compact / 1 m² footprint

Purus 20.1

The smallest of the range. Fits a 1 m² floor footprint with 20 kL/day throughput — engineered for small commercial duty, specialised process water and remote or off-grid installs where space is the binding constraint.

Throughput ~20 kL/day
Footprint 1 m²
  • Small commercial buildings
  • Boutique hospitality
  • Remote / off-grid sites
  • Specialised process water

Tailored to your site

Need a custom configuration?

The four configurations above cover the most common deployment patterns — but every site has constraints. Non-standard footprint, mixed element trains, regulated-environment materials, integration with existing infrastructure, or throughput that lands between the standard sizes. The engineering team scopes custom builds end-to-end.

Sized to your throughput

Non-standard daily volumes scoped against your duty cycle, recovery target and feedwater profile.

Custom footprint

Vertical, horizontal or modular form factors for tight plant rooms and stacked installs.

Element train mix

Multi-stage trains (e.g. 20 µm → 3 µm → Gel) tailored to your feedwater chemistry and water-quality target.

Materials & finish

Food-grade, pharma-grade or marine-grade vessel materials and surface finishes for regulated environments.

Service option

Don’t want to own the equipment?

Our Purus plug-and-play sidestream service puts a unit on your chiller circuit and we operate and maintain it for a monthly service fee. Pricing follows a short site assessment, and there is an indicative range on the service page.
