Manufacturing, Industrial & Mining Water Treatment
Cleaner Heat Transfer Higher Throughput Lower Running Costs
Every industrial site runs on water it did not choose — hard, high-TDS, recycled or abstracted. That water scales cooling circuits, boilers, heat exchangers, pipelines and pump impellers, and the plant pays for it in energy, chemicals, cleaning downtime and lost output. HydroFLOW® is chemical-free industrial water treatment technology that controls scale and biofouling from a single install — retrofitted to live plant, with no shutdown and no consumables.

Scale Doesn’t Stop Production — Until It Does
Industrial water is working water. It is recirculated through cooling towers, pushed through heat exchangers, boiled into steam, pumped down hydrotransport lines and reused until it is saturated. Every one of those steps increases the water's propensity to scale, and once it becomes supersaturated the dissolved minerals bond to an equipment surface — especially hot surfaces — as hard calcium carbonate, gypsum or sulphate scale. That is why scale forms fastest on the equipment you can least afford to lose — condenser tubes, boiler waterside, plate exchangers, spray nozzles, pump impellers and pipeline walls.
It rarely fails suddenly. It shows up first as creeping energy cost and shorter intervals between cleans, then as a stoppage nobody planned for.
Typical signs your process water is scaling up:
- Rising energy or fuel use for the same heat duty or the same pumped volume
- Chemical and antiscalant spend climbing as water is recycled harder
- Softeners, cartridge filters and strainers blinding off or seizing
- Pump impellers, flowmeters and control valves fouling
- Unplanned stoppages traced back to overheating, blockage or fouled heat transfer
What Does Scale Actually Cost Industry?
Industry and energy draw around 19% of the world's freshwater, and most of it is used more than once. The harder that water is recycled, the more concentrated it becomes — and the more aggressively it scales. The cost lands in three places at once: energy burned behind fouled heat-transfer surfaces, chemicals bought to hold minerals in check, and production lost to cleaning — whether it was on the schedule or not. Every planned descale is paid for in lost output; the stoppage nobody planned for is a crisis. Unplanned downtime alone costs the world's 500 largest companies an estimated $1.4 trillion a year — around 11% of turnover.
19% of global withdrawals
Industry and energy account for around 19% of the world's freshwater withdrawals — rising to 57% in Europe. Water reused to its limit is water that scales.
$1.4tn lost to downtime
Unplanned downtime costs the Fortune Global 500 an estimated $1.4 trillion a year — around 11% of turnover. Fouling and scale-driven cleaning are a recurring contributor.
65.7% of mines at water risk
65.7% of mining and metals facilities worldwide sit in areas exposed to a high level of at least one physical water risk — putting every cubic metre of process water under scrutiny.

The True Cost of Untreated Process Water
On an industrial or mining site, water problems hit the three things that decide the P&L — throughput, energy and maintenance. Left untreated, scale and biofilm compound across every wetted surface in the plant.
Lost Throughput & Unplanned Stoppages
Fouled exchangers, overheating machines and blocked lines force cleaning shutdowns that were never in the plan — and on a continuous process, an hour lost is an hour that cannot be recovered.
Energy Burned Behind Scale
Scale is an insulator. On condensers, plate exchangers and boiler tubes it forces the plant to burn more fuel and more power to move the same heat — a cost that never appears on a maintenance line item.
Chemicals, Softeners & COSHH Burden
Antiscalant, acid, biocide and softener salt are a permanent operating cost with storage, dosing, monitoring, handling and discharge consent attached — and they cap how hard the water can be recycled.
Pipelines, Pumps & Impellers Choking Up
In mining and high-solids process water, gypsum or sulphate scale narrows pipelines, blocks impellers, seizes valves and throws flowmeters out — driving pumping energy up and carrying capacity down.
Shell-and-tube heat exchanger: tube sheet blocked with limescale, then clear after fitting HydroFLOW® — pressure drop down from 1.2 to 0.3 and heat transfer up from 200 to 500 kcal/hour, with no acid clean and no shutdown. Read the case study →
Where the Savings Add Up.
Scale and biofilm carry a continuous cost across an industrial site — energy, chemicals, water, maintenance and lost output. Hydropath addresses six of the most significant recurring costs.
Lower Chemical Costs
Reduce antiscalant, biocide, acid and softener salt. A Texas factory cut chemical use by 75%, and Imperial Oil took antiscalant to 0.0 ppm.
Water Savings & Higher Cycles
Hold solids in suspension and run higher cycles of concentration on cooling and process water — the same Texas plant lifted its operating conductivity 3.5× on a depleting well supply.
Lower Energy & Fuel Costs
Around 1 mm of scale can cut heat transfer by about 7%. Cleaner surfaces protect duty — a Minnesota boiler gained 8% heat-transfer efficiency.
Reduced Maintenance & Downtime
Fewer acid cleans and fewer scale-related stoppages — a Philippines injection moulding plant moved from 3–6 monthly cleaning to yearly, and a cement plant eliminated daily nozzle cleaning.
Extended Equipment Life
Supporting scale and corrosion control helps protect exchangers, boilers, condensers, pumps and pipelines — deferring costly repair, relining and replacement in hard-duty service.
Fast Return on Investment
Lower chemical, energy and maintenance spend builds quick payback — Imperial Oil reported 7.2 months, and a Minnesota boiler paid back in 5.8 months, earning back 216% of the investment within a year.
Thames Water, East Hyde: struvite had been returning within weeks and narrowing the centrate line. One HydroFLOW® i Range unit on the sludge feed gave zero new scale across a six-month trial, with longer service intervals.

Industrial & Mining Water Treatment Minerals in Suspension, Not on Surfaces
A patented electronic signal that conditions process water for cooling circuits, boilers, heat exchangers, pipelines and pumps
HydroFLOW® induces a patented ~150 kHz signal into the water through the pipe wall. The signal changes how dissolved minerals behave: instead of bonding to boiler tubes, exchanger plates, nozzles and impellers as hard deposit, calcium, magnesium and sulphate ions form loose clusters in the water. When the water concentrates and becomes supersaturated, those clusters crystallise in suspension — as fine, powder-like crystals carried away in blowdown, filtration or the process stream rather than fouling surfaces.
The plant therefore gains control at the point where deposits form — the moment of crystallisation — rather than cleaning them off afterwards. There are no consumables to buy, no dosing or monitoring regime attached to it, and no pipework to modify. The signal propagates in both directions through the pipe, so one correctly sized unit conditions a whole circuit from a single fitting, working continuously on any pipe material from 15 mm tube to several metres industrial main.
Learn More About Our TechnologyOne Technology — Across the Whole Site
From the cooling tower to the boiler house to the pipeline, a single fitting alters the scale and energy position across an industrial or mining operation.
Treated Water Redissolves Deposits
Because new scale stops forming, the water regains capacity to dissolve minerals — and slowly draws existing deposits back into solution, layer by layer, while the plant keeps running.
Gradual and Safe by Design
Progressive removal avoids the risks of acid descaling — minimising dislodged flakes that can block valves and strainers, with no corroded metal and no system shutdown while it happens.
Proven at Full Industrial Scale
At a Chinese LNG plant, two Multihead 50″ units on 1,270 mm seawater condenser pipes cut bacteria by 97% and saved an estimated $56,000 a year.

Applications
Key applications for manufacturing, industry & mining
An industrial site's water problem is rarely confined to one location; it extends from the cooling tower to the boiler house to the pipeline. Each application below links to its dedicated treatment page.
Cooling Towers
Controls scale on fill, condensers and pipework so industrial cooling towers run higher cycles of concentration with less blowdown and dosing.
Steam Boilers
Reduces waterside deposit on boiler tubes, protecting fuel efficiency — and softening existing scale so it purges through blow-down.
Heat Exchangers
Reduces fouling on plate and shell-and-tube exchangers to protect approach temperatures, pressure drop and process duty.
Pipelines
Maintains carrying capacity on process, effluent, return-water and hydrotransport lines — reducing occlusion and the pumping energy behind it.
Pumps & Impellers
Keeps impellers, seals and wear rings clear of deposit — from ordinary hard water to high-solids service — protecting duty point and avoiding overheating trips.
Sulphate & Other Scaling
Addresses gypsum, barium and strontium sulphate and other ionic scaling that softeners and conventional antiscalant programmes struggle with.
High-Concentration Processes
For process water pushed to its limits — evaporators, recycled and reclaim circuits, and any stream run deliberately close to saturation.
Biofouling & Biofilm
Helps disrupt biofilm across cooling circuits, seawater intakes and process lines, protecting flow, hygiene and heat-transfer efficiency.
Corrosion
Supports corrosion control by limiting deposit and under-deposit attack on wetted surfaces — extending asset life alongside your existing regime.
Process Overview
Simple Installation. No Interruption to Cooling.
Our patented technology retrofits onto your existing pipework while the plant remains in operation.
The Fit
The HydroFLOW® unit installs around your existing pipework — cooling, boiler feed, exchanger inlet, process line or pump discharge. No cutting, no welding, no production stop. Compatible with any pipe material.
The Signal
A patented electronic signal propagates in both directions through the water, treating the whole circuit from a single point — working continuously, 24/7, with no dosing and no monitoring regime.
The Results
New scale stops forming and existing deposits gradually redissolve. Cleaning intervals stretch, chemical dosing falls, heat transfer and pumped throughput hold, and unplanned stoppages reduce.

Support & FAQ
Frequently Asked Questions
What is industrial water treatment without chemicals?
Chemical-free industrial water treatment controls scale and biofouling by changing the physics of how minerals crystallise, rather than by dosing something into the water. HydroFLOW® clamps onto the outside of existing pipework and induces a patented ~150 kHz signal through the pipe wall. Calcium, magnesium and sulphate ions form loose clusters that crystallise in suspension once the water becomes supersaturated, so they are carried away in blowdown, filtration or the process stream instead of bonding to boiler tubes, exchanger plates, nozzles, impellers and pipeline walls.
There is no salt, no antiscalant, no dosing pump and no COSHH handling — and because it is fitted externally, it goes onto live plant with no shutdown. See how the technology works →
Does it work on high-TDS and recycled process water?
Yes — that is where it tends to earn its keep fastest. Softeners become impractical and antiscalant dose rates climb steeply as total dissolved solids rise, but the signal acts on crystallisation rather than on water chemistry, so it keeps working as the water concentrates.
That is why it is used on mine hydrotransport lines, reclaim and return-water circuits, evaporator feeds and cooling systems deliberately run at high cycles. A Texas manufacturing plant lifted its operating conductivity 3.5× while cutting chemical use by 75%, and a Phoenix plant ran to 10,000 microsiemens with no scale deposits.
Will it handle gypsum and sulphate scale in mining?
Yes. Mining process water frequently produces gypsum (calcium sulphate) and barium or strontium sulphate scale, which is harder to treat than ordinary carbonate limescale.
At an Italian gypsum mine, a Custom 200 mm unit on a 700 m underground pipeline with 90 m of vertical lift ended a three-monthly acid-cleaning cycle. At Norilsk, two Custom 12″ units on 219–245 mm hydrotransport lines running at 60–70 °C gave 8.8× lower occlusion and 2.26× more pulp pumped than the untreated line alongside them. See the mining section →
Can it remove scale that has already formed?
Gradually, yes. Once new scale stops forming, the treated water regains capacity to dissolve minerals and slowly draws existing deposits back into solution, layer by layer. It is deliberately progressive rather than aggressive, which avoids the two big risks of acid descaling: dislodged flakes blocking valves and strainers, and acid attacking the metal underneath.
At a Minnesota boiler installation the signal made existing waterside scale brittle so it broke apart and purged through blow-down — stack temperature down 24 °F and heat transfer up 8%. On a blocked shell-and-tube heat exchanger, pressure drop fell from 1.2 to 0.3 and heat transfer rose from 200 to 500 kcal/hour.
Can it be fitted to a live plant without a shutdown?
Yes. The unit clamps around the outside of existing pipework — no cutting, no welding, no draining and no break in production. Installation is typically measured in minutes per unit, and it is compatible with any pipe material, from small copper tube up to 1,250 mm seawater condenser mains.
This is a large part of why sites trial it: fitting it does not commit you to a shutdown, and removing it does not either.
Does it replace our existing chemical programme?
It replaces or substantially reduces the scale-control element — antiscalant, softening and acid descaling. Corrosion inhibitor, pH control, boiler water chemistry and any statutory Legionella duties on open cooling systems are separate functions and should be maintained as required.
In practice most sites reduce rather than eliminate. A Texas factory cut chemical use by 75%; Maple Leaf Foods halved ferric dosing from 200 ppm to 100 ppm; and Imperial Oil's Kearl Lake site took antiscalant dosing specifically from 2.0 ppm to 0.0 ppm across a 12-month monitored trial.
What sort of payback should we expect?
It depends on what the water currently costs you in chemicals, energy, cleaning labour and lost production, but industrial paybacks reported by our customers are typically counted in months rather than years. Imperial Oil reported 7.2 months; a Minnesota steam boiler reported 5.8 months and 216% ROI; a Texas manufacturing plant reported under a year.
The largest single line is usually not the chemical invoice — it is the production hours recovered from cleaning shutdowns that no longer have to happen. A Netherlands block factory removed two acid cleans a year entirely, and a cement plant ended daily nozzle cleaning.
How do we prove it works on our own site?
With a documented, step-by-step testing protocol run on your own plant. We agree the baseline first — chemical dose rates, conductivity or cycles, cleaning intervals, stack or approach temperatures, pumped throughput, energy use — then fit the units and measure the same parameters over an agreed trial period.
Where possible we run it as a side-by-side: at Norilsk one hydrotransport line was fitted and an equivalent line left untreated, and the untreated line lost three-quarters of its flow in 45 days while the treated line held. Results in our case studies are measured and verified by third-party facilities managers and technical staff, and we would expect yours to be verified the same way. Talk to an engineer →
