# Purus GO

> A mobile tubular ultrafiltration unit designed and built in France by SME Bridge SAS.
> It enables the on-site diagnosis and treatment of heavily loaded industrial effluents
> (up to 10 g/L TSS) with no prefiltration and no flocculant. The goal: pay less to dispose
> of effluents and recover what has value — through on-site diagnosis, a mobile pilot trial
> before any investment, then project-owner assistance (AMO).

## The product
- Purus GO: mobile tangential-flow ultrafiltration unit with wide-bore tubes, fitted in a van.
- Specifications: 10 g/L TSS treated · 30 nm cutoff · particles and fibres up to 10 mm tolerated · pH 2–10 · ≤ 49 °C · no prefiltration · no flocculant.
- Process: buffer tank (cooling + pH neutralisation) → Purus GO → two separated streams (clear filtrate / concentrate).
- Filtrate: reuse, ion exchange or discharge depending on analyses and applicable requirements. Concentrate: reduced volume for disposal or recovery.
- Standard configuration ≈ 2 m³/h on lightly loaded waters; a 10 m³/h containerised version has been designed; 4G telemetry.
- Long-life membranes (up to 2 years depending on use), simple maintenance, small footprint.

## Applications
- Investment casting (waxes and ceramic slurries); high-pressure jet deburring.
- Machining (cutting fluids, emulsions); mass finishing and grinding.
- Surface treatment (rinse waters); bottle washing (wash waters); food industry (whey, white waters).
- Construction sites (excavation waters); prefiltration ahead of reverse osmosis, nanofiltration or ion exchange.

## Field evidence
- Demonstration at EPCC Bibracte (France): "clear water […] with no chemistry and no discharge into the environment" — Julien Langevin, Technical Manager.
- Finalist — Global Excellent Engineers Competition, Chongqing 2026 (Top 40 / 1,306) — [official list](https://cqrspx.cn).
- Partnership discussions initiated with a leading membrane manufacturer.
- Designed, built and self-funded in Saône-et-Loire, France · TRL 7.

## Project approach (SME Bridge)
1. On-site diagnosis — streams, disposal costs, recovery potential (2-day fixed fee).
2. Purus GO pilot trial — tested on your effluents, before/after laboratory analyses.
3. Project support — specification, integrator selection, follow-up.
