Configurations
Real-world Purus installations rarely run in isolation. The five-element platform pairs with reverse osmosis, UV disinfection, activated carbon and other technologies to hit specific application targets. Below are common treatment-train architectures that engineering has seen succeed in industrial practice.
Each card outlines what the pairing addresses, what Purus specifically contributes to the train, and the typical applications. Click through to discuss specifics with engineering — every site is different.
Membrane-protection pre-filtration
What it solves Reverse osmosis membranes foul rapidly without effective particulate pre-treatment. Purus 20 µm delivers high-throughput clarification ahead of the RO stage.
What Purus contributes 5,000 LMH flux, ~75% turbidity removal, regenerable element vs disposable cartridge alternatives that drive ongoing opex.
Typical applications Cooling-tower makeup recycle · brackish-water treatment · process-water polish ahead of RO.
Multi-barrier safe water
What it solves Drinking-water and recreation-water duty requires both membrane-grade filtration and disinfection. The 3 µm pre-filter (mandatory pairing for the gel element) removes the particulate load; the gel element handles the microbial barrier; UV adds the disinfection step.
What Purus contributes 3 µm + gel-membrane train (~10 nm pore), virus-grade removal (6 log), <0.05 NTU effluent, regenerable via backwash. Sold as one train, one vessel envelope.
Typical applications Municipal polish · aquatic recreation · wave parks · hospitality safe-water reticulation.
Clarity + taste / odour control
What it solves F&B and hospitality applications need taste / odour removal beyond particulate clarification. Purus 5 µm handles particulates; activated carbon polishes organics and chlorine.
What Purus contributes 5 µm element, 2,000 LMH flux, ~92% turbidity removal, regenerable pre-stage that lengthens carbon bed life.
Typical applications Brewery process water · hospitality water reticulation · beverage manufacturing.
Boiler-feed protection
What it solves Ion-exchange resins foul rapidly on particulates and have limited tolerance for suspended solids. Purus 3 µm gives fine-cut pre-filtration that protects the IX bed.
What Purus contributes 3 µm element, ~96% turbidity removal, low pressure drop, regenerable element vs continuous cartridge change-outs.
Typical applications Boiler feed-water · dam-water power applications · steam-system makeup.
Cascading clarity for high-turbidity feeds
What it solves High-particulate feedwater overwhelms a single-stage filter. Staged elements handle the load sequentially — coarse to fine — protecting downstream stages and reaching membrane-grade output.
What Purus contributes Three elements (20 µm, 3 µm, Gel) on the same Purus platform geometry. The 3 µm pre-filter is the mandatory pairing for the gel element. One supplier, one service contract, one engineering envelope.
Typical applications Storm-water recovery · mining dewatering · recycled-water polish · high-turbidity raw-water polish.
High-capacity production
What it solves Single-vessel flow is insufficient for production-scale demand. Multiple Purus vessels in parallel multiply the flow rate without changing the element or the engineering envelope.
What Purus contributes Same pump set per vessel · same footprint per vessel · same element — scaling is genuinely linear. Vessels backwash sequentially so platform uptime is maintained.
Typical applications Municipal supply · large-scale recycled-water · industrial process-water at volume.
