Solutions built around your facility

Public pools and aquatic centres

Municipal facilities have the heaviest bather loads, the largest chemical budgets and the strictest documentation. They also have the hardest constraint: a public basin normally has to hold a measurable disinfectant residual, which means the realistic goal is heavily reduced chlorine rather than none. That is still enough for the chloramine smell and the eye irritation to go, and in an indoor hall the air-quality improvement often matters as much to the staff as to the swimmers.

The buying process is different too. Procurement asks for documentation, logged parameters and evidence rather than for a brochure, and the case has to survive a budget committee. That is what the public aquatic facilities page is written around.

Hotels, spa and wellness areas

In a hotel the business case is the guest, and it is a stronger argument than the chemical invoice. Guests notice the smell in the corridor outside the spa, the stinging eyes and the dry skin afterwards, and they write about all three. Hotel basins are also classified more permissively than public ones, so fully chlorine-free operation is realistic more often.

The technical picture is more tangled, though: one plant room typically serves a pool, a spa area and a hot tub, each with its own turnover and its own risk profile. Hot tubs in particular need their legionella control regime left fully intact. The detail is on hotels and spa.

What actually differs in the specification

When we quote two facilities of the same water volume, these are the lines that come out differently:

• Residual requirement. Whether your basin has to carry a measurable disinfectant decides whether the outcome is chlorine-free or chlorine-reduced. It is a classification question, not a technology question.
• Flow and turnover. Sizing follows flow rate, never basin length. A busy 25-metre municipal pool and a hotel pool of the same volume are not the same unit.
• Load profile. A school timetable produces sharp predictable peaks; hotel occupancy produces long unpredictable ones. The plant has to cope with the shape, not the average.
• Documentation. Municipal buyers want logged parameters, service intervals and evidence. Hotels usually want to know what changes for the guest and what the annual cost becomes.
• Number of basins. One unit per body of water, sized individually. Hotels almost always have more than one; municipal facilities often have a training pool and a therapy basin as well.
• Where the money comes back. Municipal: chemical spend, ventilation load and building wear. Hotel: the same, plus reviews and repeat bookings — which is real value but harder to put on an invoice.

Wellboat oxygenation and disinfection

A wellboat is not a building, but its questions are just as specific. Two separate jobs share one vessel: holding dissolved oxygen stable with fish on board through loading, transport and unloading, and disinfecting the empty wells, piping and equipment between assignments. NanoSWIM answers them with two systems, the ABAN-20 oxygenation module and the ARVAND-O3 ozone-nanobubble skid. Both are offered through a pilot programme and sized per vessel, and neither has on-board results yet. The detail is on wellboat oxygenation and disinfection.

If none of these is your facility

Private pools, municipal and industrial water treatment and live fish transport beyond the wellboat systems are all covered, just not from this page — those sit under applications instead, organised by what the water has to do rather than by who owns the building.

And the honest boundary applies here as it does everywhere on this site. Nanobubble treatment is a circulation-loop technology: it needs a loop to install into and a flow rate to design around, it does not replace filtration, and on its own it leaves no lasting residual in the basin. Where the pool is small, lightly used and already cheap to dose, the capital cost may not pay back on chemicals alone. We would rather tell you that at the enquiry stage.
