Reverse osmosis
Brackish and seawater trains from 2 to 200 m³/h, tapered two-stage arrays, isobaric energy recovery on high-salinity duties.
Industrial membrane separation
Membrane water treatment plants engineered to a guaranteed permeate spec
Reverse osmosis, ultrafiltration, nanofiltration and EDI trains built to order — from 2 m³/h polishing skids to 200 m³/h seawater desalination halls. Every train is projected, witness-tested and delivered with its own performance envelope.

Separation technologies
Six membrane processes, one process desk
Each train is projected in-house against your feed analysis before a single vessel is cut. We do not resell a catalogue — we size the array, pick the element and stand behind the permeate number.
Ultrafiltration
Outside-in PVDF hollow fibre on fixed-flux control. The stage that decides whether the RO downstream reaches its warranty life.
Nanofiltration
Selective softening and colour removal where full demineralisation would be an expensive over-treatment.
Electrodeionization
Continuous chemical-free polishing to 18.2 MΩ·cm for microelectronics, pharmaceutical and power station duties.
Water reuse
MBR and tertiary RO trains that take a treated effluent back to process-grade water instead of to the outfall.
Seawater desalination
Full desalination halls with pressure-exchanger energy recovery, boron control and remineralisation.
Why work with us
Engineered, built and supported in-house
One team carries your project from the first enquiry to years of reliable operation — nothing is handed off, and nothing gets lost between departments.
01
Designed around your requirement
Every system starts from what you actually need — your water, your duty, your site — not from a fixed catalogue configuration.
02
Built and tested before it ships
Each unit is assembled and fully tested in our own workshop, so commissioning on site holds no surprises.
03
Supported after handover
Operator training, spare parts and engineering support from the same people who designed the system.
Equipment catalogue
Standard trains, project-specific arrays
Every model below is a real starting configuration with a published envelope. The array is then re-projected for your water.

Where our plants run
Duties we build for
Power generation
Demineralised boiler make-up
RO plus EDI trains feeding subcritical and supercritical boilers to a silica-limited spec.
Life sciences
Purified water generation
Sanitary 316L skids, orbital-welded distribution and full IQ/OQ documentation packages.
Municipal reuse
Tertiary effluent recycling
MBR followed by tertiary RO returning treated effluent to cooling and irrigation duty.
Coastal supply
Seawater desalination
Pressure-exchanger trains with boron control and calcite remineralisation for potable supply.
96 h
Standard crossflow trial before a difficult water is quoted
Process engineering
We project the water before we quote the steel
A membrane plant is only as good as the assumptions behind its projection. Clearflow runs every enquiry through a full ionic balance, a scaling index check and — where the water is unusual — a bench-scale crossflow trial on the actual sample before a price is issued.
- Full ionic balance and charge-balance check on the supplied analysis
- LSI, S&DSI and sulphate saturation screening at design recovery
- Element-by-element flux and concentrate velocity profile
- Antiscalant selection and dose modelled at worst-case temperature
- Specific energy calculated with and without energy recovery
- Witnessed factory acceptance test on clean water before despatch
From enquiry to handover
A predictable delivery route
Four gates, each with a document you actually receive — not a milestone chart you never see again.
01
Water analysis review
You send a full analysis and a duty. We return a charge-balanced review, the scaling risks and the recovery ceiling your water will physically support.
02
Projection and proposal
A projected array with element-by-element flux, a specific-energy figure, a P&ID and a priced scope. Two working days on standard duties.
03
Fabrication and FAT
Skid built in our assembly bay, wetted parts certified, then a witnessed clean-water factory acceptance test against the projection.
04
Commissioning and care
Site installation supervision, membrane wet-up, performance verification at contract conditions, then a normalised performance monitoring plan.
