Systems

Every system we build, grouped by what it physically does to the water — filter it, push it through a membrane, exchange its ions, or kill what lives in it.

4 families 11 systems 0.5 – 500 m³/hr Design · build · commission

Four families, eleven systems. The grouping is deliberate: systems inside a family share a working principle, so they share sizing logic, materials, failure modes and the questions an engineer will ask you before quoting.

Almost no plant buys one. A working train is normally two or three families in sequence — filtration to protect a membrane, a membrane to carry the bulk load, resin to polish, disinfection to hold the result. Start with the family that matches your problem; the category page tells you what has to sit either side of it.

How The Families Sequence Colour = family

A representative high-purity train, coloured by the family each stage belongs to. Not every plant needs every stage — but the order rarely changes.

The Four Families Eleven systems

Each family has its own category page — working principle, placement in the train, a selection matrix and the systems inside it. Jump straight to a system, or read the family first.

FILT Pretreatment
Water Filtration Systems
Media beds · gravity or pressure · backwashable
The first thing water meets and the cheapest insurance in the plant. Sand and multigrade media strip suspended solids and turbidity; activated carbon takes out chlorine, taste, odour and organics before they reach a membrane. Get this stage wrong and every stage after it fails early.

MEM Bulk Removal
Membrane Separation Systems
Pressure-driven · UF → NF → RO by pore size
Separation by physical exclusion — push water through a barrier and leave the contaminant behind. The workhorse family for bulk salt and solids removal, and the stage that decides your recovery, your reject volume and most of your running cost.

IX Polishing To Limit
Ion-Exchange Systems
Resin beds · regenerable or continuous
Swaps the ions you do not want for ones you can live with. Where membranes remove a percentage, resin removes to a limit — which is why hardness control, demineralisation and final polishing to sub-ppb conductivity all live here.

DIS Microbial Control
Sterile Disinfection Systems
Chemical-free · no residual, no by-products
Microbial control without adding anything to the water. Ozone generated on site oxidises and then decays back to oxygen; UV light scrambles DNA as water passes a lamp. The only disinfectants acceptable inside a purified-water loop.

Start From The Problem What is wrong with your water

If you do not know the equipment name, start here. Each line is a complaint we hear, and the family that answers it.

The complaint
What is actually happening
Family
Water is cloudy, or filters downstream clog within days
Suspended solids and turbidity arriving untreated at the plant inlet.
Chlorine smell, and RO membranes failing early
Free chlorine oxidising the membrane surface — an unprotected polyamide film.
Scale in boilers, heaters and cooling circuits
Calcium and magnesium hardness precipitating on hot surfaces.
TDS too high for the process; product quality varies
Dissolved salt load that no filter can remove — it needs separation.
Need sub-ppb conductivity, and cannot handle acid or caustic
A polish specification tighter than membranes reach, without regeneration chemicals.
Discharging too much, and paying for fresh water twice
Recoverable effluent leaving site instead of returning to the front of the train.
Microbial counts drift up in storage between batches
Stagnant stored water with no continuous sanitising duty on the tank.
Colour, odour or COD that survives conventional treatment
Refractory organics that need oxidising rather than filtering.

Send the water analysis. We will send back the train.

A raw-water report, your flow rate and the quality you have to hit are enough for us to lay out the stages, size each one and tell you where the cost actually sits — before anyone talks about a quotation.
