Industries we power

A salmon farm, a flotation cell and a cooling circuit share nothing commercially. Their water fails in one of two ways: too little gas dissolved, or too much suspended.

Nanobubbles answer both. Cavities under 200 nm stay suspended for days to weeks instead of bursting in seconds, and their negative zeta potential lifts fine solids, oils and organic film. Nothing is dosed, so nothing is left behind — more on water treatment without chemicals. Only the symptom changes by sector.

Blowers at full load, a consent date closing in. Energy per kilogram of oxygen actually transferred is the honest comparison, and flotation removes 80 %+ of suspended matter with no coagulant. Denser sludge means fewer transports — our approach to wastewater aeration.

Two complaints bring growers here: emitters that block, and a root zone going anaerobic after irrigation. Oxygen held in suspension reaches the roots instead of degassing in the header, and air is usually gas enough — more on irrigation water treatment.

A dosing regime treats bulk water; biofilm lives on surfaces, under a layer the biocide barely reaches. Bubbles that persist for days get there instead, and controlled film means fewer cleaning cycles and less downtime — our approach to cooling tower water treatment.

Standing water arrives seasonal: warm upper layer, oxygen-starved bottom, odour and algae. Surface aerators move water; nanobubbles put gas into it and leave it there for days to weeks — more on pond aeration.

Flotation cells lose the fine fraction: a conventional bubble is too large and too short-lived to catch it. Charge and interface area do it instead. Abrasive slurries are why the platform carries a ceramic stage beside membrane and venturi — more on froth flotation.

Produced water carries dispersed oil and fine solids, and the usual answer is a chemical programme with its own storage and disposal burden. Charged bubbles float both off, leaving less liquid to dewater and less mass downstream — more on produced water treatment.

Two problems at once: process water that must be clean, and surfaces that must be clean with nothing left behind. Ozone nanobubbles disinfect and revert to oxygen; the bubbles themselves degrease — more on food processing water treatment.

Membranes fail on what reaches them: turbidity, fine solids, biofilm. Floating solids out of the intake keeps them off the membrane, and 50 %+ turbidity reduction is published for that duty — more on desalination pretreatment.
