Industries

Same equipment, different rulebook. What each sector must prove about its water — and where plants in that sector usually come unstuck.

7 sectors GMP · IP / USP / EP Discharge consent Audit-ready documentation

An RO skid does not care what industry it is in. The paperwork does. A pharmaceutical loop and a textile recovery plant can share almost every component and still be entirely different projects — because one is qualified against a pharmacopoeia and the other against a discharge consent.

These pages are written for engineers and plant managers inside each sector: the governing specification, the failure mode that costs most, the instrumentation you will be asked to show, and the train that satisfies it.

IP / USP / EP purified water · WFI · sanitisable loops

The only sector where the water system itself is an audited asset. Conductivity, TOC and bioburden must be continuously demonstrable; every weld, slope and dead leg is a documented decision. Generation and distribution are separate builds with separate qualification packages — which is why they have separate pages here.

Other Sectors Six

Each page states the governing specification, the usual failure mode, and the train we would propose against it.

Semiconductor
Semiconductor & Microelectronics
18.2 MΩ·cm · TOC & particles in ppb
The tightest water specification in industry. Resistivity, TOC, dissolved oxygen, silica and particle count are all controlled simultaneously, and the loop never stops moving.
Usual failure mode
Particle and TOC excursions traced to loop materials and dead legs rather than the generation plant.

Food & Beverage
Food & Beverage
Potable + ingredient grade · microbial stability
Water is a declared ingredient, a cleaning agent and a utility on the same site — three different specifications behind one inlet. Taste and mineral balance matter as much as purity.
Usual failure mode
Microbial drift in storage between production runs, and CIP rinse water quality nobody logged.
Sector page →
Textile
Textile & Polyester Yarn
Hardness & iron control · high recovery
Dyehouse water decides shade reproducibility, and effluent decides whether the plant keeps running. Recovery is no longer optional in most textile clusters.
Usual failure mode
Shade variation from hardness and iron swings; recovery plants sized on averages, not dye-batch peaks.
Sector page →
Petrochemical
Petrochemical
Boiler feed · silica & conductivity limits
High-pressure steam is unforgiving about silica and conductivity, and condensate is too valuable to throw away. Cooling and process circuits run alongside at very large volumes.
Usual failure mode
Silica carry-over into turbines, and condensate returned to the boiler without polishing.
Sector page →
Pulp & Paper
Pulp & Paper
Very high volume · colour & COD load
Enormous throughput at modest quality, with a heavy organic and colour load on the effluent side. The economics live in reuse and in how little fresh water each tonne consumes.
Usual failure mode
Fresh-water intake creeping up because recovered water is not clean enough to return to the machine.
Sector page →
Chrome Plating
Chrome Plating & Metal Finishing
DM rinse water · heavy-metal recovery
Rinse water quality shows up directly as spotting and adhesion defects, and the rinse itself carries metal that must be recovered rather than discharged.
Usual failure mode
Spotting from rinse conductivity drift, and metal-bearing rinse sent to effluent instead of recovery.

What Each Sector Is Judged On Read across

The governing parameter differs by sector, and it drives the whole design. Everything else is negotiable; this column is not.
