The real cost

What’s really driving up your pool costs?

Managing water in a commercial pool involves three recurring financial problems – all of them solvable.

01

Does HydroFLOW help reduce Cryptosporidium risk?

Cryptosporidium is a chlorine-resistant parasite, so physical filtration — not chemical disinfection — is the primary line of defense against it in pools.

✓ With HydroFLOWElectronic flocculation clusters fine particles, including those in the size range relevant to the parasite’s oocysts, into larger clusters the filter captures more effectively. The treatment supports the existing filtration barrier and complements it.
02

The most expensive business water tariffs

Commercial and public swimming pools in Israel receive no subsidy and are charged the “high tariff” of water corporations – roughly NIS 13.5-15.6 per cubic metre of water and sewage. Every backwash dumps dozens of cubic metres to drain – billed twice.

✓ With HydroFLOWUp to 50% fewer backwashes – a direct cut to your water and sewage bill.
03

Massive water waste in filter backwashing

In each backwash, water already heated and treated with expensive chemicals is discharged to sewage – then cold water must be refilled and reheated from scratch. Fuel, gas and electricity costs climb accordingly.

✓ With HydroFLOWFewer backwashes means retained heated water and significantly lower energy costs.
04

Chloramines, turbidity and chemical costs

Tiny organic particles slip past the filters, cloud the water and create chloramines – responsible for the sharp chlorine smell, eye-stinging and accelerated corrosion. The traditional fix: more chemicals, more cost.

✓ With HydroFLOWElectronic flocculation clusters particles – fewer chloramines, clearer water, less chemical spend.
05

Green water or algae in the pool

Cloudy water is usually caused by particles the filter misses; green water is an algae bloom.

✓ With HydroFLOWImproved filtration and disrupted biofilm — which algae rely on — help address both conditions: at a wave pool in Ukraine, the water cleared to a blue hue within 12 days. The treatment works alongside the existing disinfection regimen, not in place of it.

The solution

How does HydroFLOW work?

The system is installed externally on existing piping ahead of the filters – no pipe cutting, no pool downtime. A constant electronic signal at ~150kHz performs physical flocculation: causing microscopic particles and chloramine compounds to coagulate into large clusters that the sand filter captures easily.

Biofilm disruption
Less shelter for bacteria

The signal disrupts biofilm attachment to surfaces, and supports more effective action by existing disinfectants.

Up to 50%
Fewer backwashes

Larger flocs are captured more easily by the filter — reduced backwash frequency, depending on bather load and filter type.

About 1.5 years
Typical payback period

Depending on pool size, bather load and local water tariffs — payback time can vary from pool to pool.

None
Infrastructure changes

No cutting, welding or pool shutdown. The pool operates throughout the entire installation.

Installation process

Three steps to an advanced solution.

01

Installation

The HydroFLOW system is installed externally onto the pool’s water pipework, with no cutting or pool shutdown.

02

Treatment

The electrical signal is induced in both directions through the water, treating the whole circulation system from a single point – continuously, 24 hours a day.

03

Result

Filtration improves within days. As water clears, chlorine dosing and backwashing can be progressively reduced – delivering a more efficient, cost-effective operation.

Exactly where the system works around the pool circuit

Filtration and clarity

Larger flocs are captured more easily by the filter — clearer water, fewer backwashes.

Preventing filter caking and channeling

Prevents caking and channeling in the filter media — the filtration layer stays effective over time.

Limescale in heating systems

Protecting heaters and heat exchangers in heated pools and hard water — maintaining energy efficiency.

Biofilm and bacteria

Disrupting biofilm attachment to surfaces and pipework — less shelter for bacteria, safer water.

Pumps

Keeping circulation pumps free of limescale and biofilm, for reliable flow.

Chemical optimisation

Less chlorine, acid and flocculants required — alongside a properly maintained disinfection regime.

Applications

Who is it for?

Public and municipal swimming pools

A perfect solution for community sports centres seeking to significantly cut operating expenses while maintaining a high service standard for swimmers.

Hotel and guesthouse pools

Maintaining an aesthetic standard and crystal clarity with no byproduct odours that bother guests – while achieving significant savings in ongoing costs.

Country clubs and water parks

Protecting extensive filtration systems with a fast ROI – often within less than 12 months, purely from direct savings on water and sewage payments.

FAQ

Your questions answered

How does HydroFLOW improve pool filtration?
The system transmits an electronic signal into the pool pipework that causes microscopic particles to coagulate into larger clusters (flocculation). Larger clusters are far easier for the sand filter to capture – filtration is more efficient, water is clearer, and the filter stays effective for longer between backwashes.
How much can backwash frequency be reduced?
Depending on pool volume, bather load and filter type, backwash frequency can be reduced by up to 50%. Every backwash saved means dozens of cubic metres less discharged to sewage – a direct saving on the water corporation bill.
Does installation require pipe cutting or pool shutdown?
No. The HydroFLOW unit is clamped externally onto existing pipework, with no cutting, welding or structural changes. The pool continues to operate throughout the entire installation process.
Does it help with chlorine smell and chloramines?
Yes. Electronic flocculation reduces the organic particles in the water – the particles that react with chlorine to create chloramines. Fewer chloramines means less sharp chlorine smell and less eye-stinging for swimmers.
How does it help with bacteria and Legionella?
Validation tests conducted by global company SGS and ALS laboratories showed a reduction of up to 99% in bacteria, including Legionella. The electronic signal disrupts bacterial cell membranes and breaks down biofilm.
What is the expected return on investment?
At typical commercial pools in Israel, payback is reached in less than 12 months – thanks to combined savings in water, sewage, chemicals and heating energy. The exact figure depends on pool volume and the local water corporation tariff.
