Resort pool: 85% less chlorine
A 2,500 m² hotel pool complex: what changed in chlorine consumption, operating cost, hall air and water clarity — and which of those are measurements.
Read the case studyThis page collects the nanobubble case studies NanoSWIM can put figures behind. Two installations are written up in full, with the client anonymised for commercial confidentiality. We would rather give you two projects you can interrogate than a wall of logos you cannot check. If your sector is not represented yet, ask us and we will point you at the closest comparable site we have.
Every figure on this page is one we can source. Everything else is labelled as description, not measurement.
You will not find a filter widget here. With this many published references, a filter would be decoration. Instead, each sector below says what we can show today and — just as important — what we cannot show yet.
Two projects are documented in detail: a resort pool complex and an Atlantic salmon facility. For the other sectors we work in, we can usually arrange a conversation with an operator, which is worth more than a page anyway.
A headline customer count is the easiest thing in the world for a supplier to publish and the hardest thing for a buyer to check. This page is deliberately not built around one.
Pools are where most of our pool project references sit, and where buyers ask the hardest questions — a municipal facility cannot be run as an experiment for a season to see what happens.
Be aware of one structural difference before you read the pool case study: it is a hotel installation, not a municipal one. A public pool in Norway generally has to hold a measurable disinfectant residual in the basin, so the realistic outcome there is a large chlorine reduction rather than zero chlorine. If you are specifying a municipal facility, start with solutions for public facilities, then read Nanobubbles vs chlorine for what actually changes and what does not.
For public projects we would rather set up a site visit and a direct conversation with someone who operates a system than point you at a marketing page. Ask, and we will arrange whatever the operator is willing to do.
The fullest write-up we have is Resort pool: 85% less chlorine. It covers a 2,500 m² pool complex at a resort in southern Europe that cut chlorine consumption by 85% and the running cost of water treatment by 60%.
Two things are worth stating plainly. The client is not named: that is commercial confidentiality, and in this market it is normal rather than evasive. And the write-up separates the two published figures from the qualitative changes around them — chlorine smell in the hall, water clarity, how often chemicals were ordered — which are labelled as description because that is what they are.
Hotel and spa buyers usually care about guest experience before they care about chemistry, which is a fair way round. The commercial argument for that sector is on solutions for hotels and spa.
Atlantic salmon farm: 28% higher survival covers nanobubble oxygenation at a Norwegian salmon producer running a recirculating (RAS) facility. The published results there are higher survival through grow-out and a substantial increase in dissolved oxygen; no growth figure was measured.
Aquaculture buyers tend to be the most numerate readers this site gets, so that page is written to be picked apart: what was measured, what was not, and which parts of the explanation are mechanism rather than data.
The application detail — transport tanks, well boats, holding and grow-out — sits under live fish transport.
Here we have to be straight with you. We do not yet have a published case study for municipal or industrial water treatment with figures we are permitted to share. We sell into these sectors, and we would rather say that plainly than imply a track record we have not documented.
What we can offer instead is the method. Before anything is installed we will agree in writing what gets measured on your site and how: chemical consumption, dissolved oxygen, turbidity, energy draw, and whatever your discharge consent or internal control system actually holds you to. Then we re-measure the same things at the same points afterwards.
That is the difference between a reference and a claim, and it is worth insisting on from every supplier you are talking to.
Supplier websites in this industry carry headline counts: customers served, countries shipped to, installations delivered. Ours has too. Treat all of them as background rather than as evidence. They tell you a company has been trading. They tell you nothing about whether a system will hold up in your building, at your bather load, under your municipal health officer.
Three questions are worth more than any of those totals, and they are worth asking of every supplier on your shortlist, including us:
If a supplier cannot answer the third question, the first two do not matter very much.
If you are seriously considering an installation, there is a version of the project where the measurement is designed in from the start instead of reconstructed a year later from half-remembered invoices.
It works like this. We agree the baseline before commissioning — current chemical consumption, current water-quality logs, current complaint volume, current energy draw. We agree what will be re-measured, at which points, and when. And we agree in advance what may be published and what stays private, including the option of a fully anonymous write-up like the two on this page.
Become our next reference and we will send you the measurement plan we use, so you can judge the method before you commit to anything at all.
Being a reference is optional and it does not change your price. A supplier who ties a discount to a testimonial is buying evidence rather than producing it.
Two case studies with figures behind them, plus where to go when your sector is not covered yet.
A 2,500 m² hotel pool complex: what changed in chlorine consumption, operating cost, hall air and water clarity — and which of those are measurements.
Read the case studyNanobubble oxygenation in a RAS facility: survival through grow-out and dissolved oxygen, with the economics explained rather than asserted.
Read the case studyNo published case study yet. What we can give you is the compliance detail, a realistic account of residual disinfection, and a reference conversation.
Public aquatic facilitiesWhich regulations a Norwegian buyer has to satisfy, and exactly what documentation to demand from any supplier — including us.
Standards and complianceA short test you can apply to every case study you are sent this month.
“85% less chlorine” means something if you know it is consumption at one named facility over a comparable period. Without a basis it is a slogan.
Size, type, indoor or outdoor, load pattern. A result from a lightly used private pool tells you very little about a 25-metre municipal basin.
Air quality, clarity and comfort are real benefits, and they are usually described rather than measured. That is fine — as long as nobody pretends otherwise.
Confidentiality is normal in B2B. A supplier who anonymises everything and explains nothing is a different matter.
A reference call with an operator will teach you more in twenty minutes than any page on any supplier’s website, ours included.
Tell us what kind of facility you run and what you are trying to fix. If we have something comparable, we will say so and try to arrange an introduction. If we do not, we will tell you that too — and explain what we would measure on your site instead.
