Filter Builder
Five filter elements, one vessel. Pick an option, set your duty cycle, influent turbidity and economics, and see flow, daily output, water quality and the annual return live. Same pumps, same footprint — different element, different outcome.
The 30-element Purus vessel runs a range of filter elements at a consistent geometry. Pore size sets the flow, the removal target, and the operating philosophy. Coarser elements push more volume; the gel membrane brings the microbial removal and regenerable economics.
All values calculated against the standard Purus vessel configuration. Daily volumes assume 24 h running — adjust below in the builder if you run a different duty cycle.
| Filter element | Pore size | Flux (LMH) | Flow (L/min) | Daily volume (m³, 24 h) | Turbidity removal | Effluent NTU | Long-term recovery | Savings vs cartridge / yr | Best for |
|---|---|---|---|---|---|---|---|---|---|
| 20 Micron | 20 µm | 5,000 | 471 | 679 | 75% | 2.5–5.0 | 93–95% | $800 – $1,500 | Highest throughput / lowest pressure drop |
| 10 Micron | 10 µm | 3,000 | 283 | 408 | 85% | 1.5–3.0 | 91–94% | $1,200 – $2,200 | Balance of flow and particle removal |
| 5 Micron | 5 µm | 2,000 | 189 | 272 | 92% | 0.8–1.5 | 90–93% | $1,800 – $3,000 | Solid flow with clarification |
| 3 Micron | 3 µm | 1,500 | 141 | 204 | 96% | 0.4–0.8 | 89–92% | $2,500 – $4,000 | Finer removal, still high flow |
| Gel Membrane | ~10 nm | 1,000 | 94 | 136 | 99.9%+ | <0.05 | 88–92% | $6,000 – $15,000+ | Virus removal, regenerable, lowest opex |
Adjust the inputs and the right-hand panel updates live. The defaults are the published technical values — the cost and duty-cycle fields are placeholders for you to swap in your own procurement and operating numbers.
Why this option: —
These are the technical anchors the builder runs on. Flow and capacity figures are derived from Blue Quest’s engineering parameters and operating data. Figures are subject to site-specific verification.
Flow, capacity and savings values are derived from Blue Quest engineering parameters and operating data. Detailed engineering specifications are proprietary and not published.
Hours running × duty cycle × flow. Coarser filters typically run 100% duty; gel defaults to 80% to allow backwash.
Effluent NTU = influent NTU × (1 − removal%). The gel membrane figure (99.9%) is grounded in Blue Quest trial data showing ~99.999% bacteria and particulate removal, published conservatively. The four micron filters’ percentages are indicative starting points subject to site-specific verification.
Annual loss = backwash volume per cycle × 12 cycles/day × 365. Per-filter backwash volumes are indicative; real cadence varies with fouling.
Each Purus vessel runs on a dedicated pump set sized for the platform. Multi-vessel installations scale the pumping infrastructure proportionally; vessels backwash sequentially to maintain uptime.
20–3 µm savings benchmarked against an equivalent high-flow 6″ pleated polypropylene cartridge system (3M / Pall / Pentair / Parker class): ~$200–$400 per cartridge depending on micron rating, replaced every 2–4 months in industrial service, plus labour (~$60–$80 per change-out), housing wear and disposal. Figures from vendor and trade-supply pricing data.
Gel savings benchmarked against the full multi-barrier safe-water train required to match virus-grade output: sediment pre-cartridges + UF hollow-fibre module (~$1,000+ per 4″×40″ unit) + UV lamp + cleaning chemicals + integrity testing. Ceiling reflects upper-end multi-stage RO/UV combinations.
