Run it on your own water before you buy it

Nanobubble performance depends on the water and the duty, not on a datasheet. So the order is: run it on your system first. The acceptance indicators and test method are agreed in writing before the unit ships; a test report follows at the end. If the targets are met we talk purchase. If not, the unit goes back under the agreement.

Why we send a unit instead of a quotation

The same machine can produce twice the result on one site and half of it on another. That is not a defect in the machine — it is the water.

01

Nameplate is not site result

Flow, bubble size and concentration on a specification sheet are measured in clean water under standard duty. Your water has hardness, chlorides, oil and suspended solids. The number that matters has to be measured where the unit will run.

02

Duty decides, not marketing

Cycles of concentration, velocity, temperature, pH and the existing chemical regime all move the outcome. Buying without a trial moves all of that uncertainty onto you.

03

Swap promises for data

Before delivery we write down the indicators, the test method and the sampling points, and both sides sign. Then we read the result. Nobody has to be persuaded by a slide.

How the trial runs

Six steps, each with something handed over at the end of it.

  1. Step 01 — Send the duty. Flow, water analysis, existing process and the problem. More detail gives a sharper assessment.
  2. Step 02 — We assess. A reply within one business day on whether a trial makes sense, the model we would send, and how it would be installed. If it is not a fit, we say so.
  3. Step 03 — Agree the KPIs. Indicators, test method, sampling points and cycle length confirmed in writing and signed by both parties.
  4. Step 04 — Ship and install. We supervise installation and commissioning. Most duties are side-stream, so no shutdown in the majority of cases.
  5. Step 05 — Run. Continuous operation for 15–30 days as agreed, with operating data logged and samples taken on schedule.
  6. Step 06 — Report, then decide. A test report compared against the pre-trial baseline. Met: we talk purchase. Not met: the unit is returned under the agreement.

Acceptance indicators to agree up front

An indicator has to be measurable, repeatable and comparable. The table is a starting point; the final list follows your site conditions.

ApplicationSuggested indicatorTest methodTypical period
Cooling water / hot-water descalingFouling resistance or heat-exchange approach, scale inhibitor dose, turbidity, scale thicknessSide-stream connection; before/after comparison over matched periods20–30 days
Ozone advanced oxidationCOD / colour removal, ozone dose, off-gas ozone concentrationParallel comparison or staged test15–25 days
Aquaculture oxygenationDissolved oxygen, ORP, ammonia, feed intake and survivalZoned within one pond, or matched-period control15–30 days
Flotation / oil removalEffluent TSS and oil, sludge water content, chemical dosePaired influent / effluent sampling15–25 days
Membrane fouling controlRate of transmembrane pressure rise, chemical cleaning interval, flux recoveryCompare against a section without the unit20–30 days

Indicators and test method are agreed once, before delivery, and are not changed unilaterally mid-trial. Sampling points, sampling frequency and who measures — your laboratory or a third party — are written into the trial agreement.

Trial terms (public summary)

Commercial terms are those of the signed trial agreement. This is the part we publish.

Who can trialEnd users; projects led by a design institute or EPC; regional partners (transferable to their customer)
Which modelsMatched to flow and application — see below; the assessment decides
Period15–30 days, set by what the indicator needs to show
CostDeposit and rental are agreed in the trial agreement by model and period; credited against the purchase if you buy
Basis of judgementKPIs and test method agreed in writing before delivery and signed by both parties
ReturnIf the agreed indicators are not met, the unit is returned under the agreement, with freight responsibility written in
Use restrictionsNo dismantling; unit sealed; transit insurance during shipping and installation; normal wear is not chargeable

Request a trial unit

Seven fields, under a minute. We read the duty; we do not run a call centre. If it is not a fit we tell you.

The form composes an email in your own client — nothing is stored on this server, and no data leaves your machine until you press send.

Decide on data, then decide whether to buy

Send the water analysis and system parameters. We reply within one business day on whether a trial makes sense, with the model we would send and the indicators we would propose.
