Water you have already treated can go back to work
If your plant treats water in order to discharge it, you are paying twice: for the water you buy and for the water you let go. Regeneration returns that flow to the process at the quality each use needs — no more, no less. Circular economy applied, not a slogan.
Typical uses of reclaimed water
- Cleaning of plant, floors and equipment
- Irrigation of green areas and dust control on roads
- Make-up to cooling circuits and towers
- Washdown, vehicle and machine washing
- Non-critical process water, depending on the sector
Buying clean water to throw it away almost clean
Reuse stops being an abstract idea when you set it next to the water bill, the discharge cost and campaign restrictions.
Rising mains consumption
All the water that enters the plant is bought at drinking-water prices, even if it is used to wash a floor or water a road.
Discharge cost
Every cubic metre that leaves also costs: the levy, the permit conditions and, in some cases, haulage to a waste manager.
Restrictions and drought
Supply restrictions that arrive right at the production peak and put the operation at risk.
Already-treated effluent that is wasted
Plants with their own treatment that discharge water which only needs a polishing stage to go back into the circuit.
Customer and tender requirements
More and more tenders and supply-chain audits ask about water use and circularity measures.
Fear of oversizing
The reasonable fear of putting in an expensive plant for a use that does not need it. The answer is to match quality to use, not to maximise it.
Reclaim only to the quality the use requires
The principle is simple: first you define what the water will be used for, and only then how much to treat it. Treating too much makes the plant expensive without adding value; treating too little makes it useless.
Site water balance
What comes in, what goes out, where, and at what quality. That map is what shows which stream is worth reclaiming and which is not.
Definition of the end use
Cleaning, irrigation, cooling or process. Each destination has its requirements and its reuse rules, and from those come the design target parameters.
Reclamation train
Solids separation and filtration, advanced oxidation (POAC) when difficult load remains, and final disinfection by UV or electrolysis depending on the use and the storage time.
Storage and reclaimed-water network
A tank, pumping and a network separate from drinking water, labelled and independent to avoid any cross-connection.
Control, logging and maintenance
Measurement of the reclaimed-water control parameters and a running log, with operator training and consumables delivered with the first installation.
Be careful with the figures. The recoverable share of water depends on the real site balance, effluent quality and the end use: we do not give savings figures before seeing those data. Reuse is also subject to regulatory requirements and to a permit depending on the use; we check that case by case before proposing anything.
What you gain by closing the loop
Saving on both sides
Every cubic metre reclaimed is one you do not buy and one you do not discharge. The impact comes in on both sides of the account.
Less dependence on supply
A flow of your own that cushions restrictions and cuts in the months when you produce most.
Evidence for customers and audits
Verifiable consumption and circularity data for tenders, sustainability reports and customer audits.
A plant sized to the job
A system sized to the end use, compact and expandable if another demand is added tomorrow.

Where reuse pays
| Industry with its own treatment | You already treat the water: what is missing is the polishing stage and the network to send it back to cleaning, irrigation or cooling. |
|---|---|
| Vehicle and machine washing | High, concentrated consumption; recirculating the wash water is the most direct case. |
| Food industry | Wash and process water with a clear destination in wash-down and auxiliary services. |
| Sites with green areas and roads | Irrigation and dust control, uses that do not need drinking quality and consume a large volume. |
| Hotels, campsites and sports complexes | High seasonality and pressure on supply right in high season. |
| Aggregate plants and quarries | Recirculation of wash water with pH and suspended-solids control. |
Can this water be brought to drinking quality?
Start from the outlet of your WWTP or from the industrial simulator. The reuse train (activated-glass filtration, chlorination and pH, advanced oxidation, carbon polish, cavitation and UV) is sized on your flow rate and tells you whether it gets there, whether it sits on the edge, or which parameters stay out. It is more approximate than the wastewater simulator and we say so: a test closes it.
The train, stage by stage
Where we start and where we get to
Guidance, not a commitment: a test on your water closes the result. Target: parametric values in RD 3/2023 (Annex I). No stage desalinates: if the only thing that fails is conductivity, the route is reverse osmosis or ion exchange.
Request the reuse studyLet’s see whether your water can go back into the process
We need little to start: approximate consumption, what you do today with the treated water, and which use you would like to put it to.
We will tell you frankly whether your case pays or not. When it does not, we say so too: that is the only way the next conversation is worth having.
