The problem
Dead Zones And Standing Sludge
Nutrient-rich runoff drives eutrophication, eutrophication drives algae, and the decomposition that follows a bloom consumes what oxygen was left. Over 2,300 lakes and rivers are contaminated. Without oxygen aquatic life dies, sediment chemistry turns, and organic sludge accumulates in the layer nobody can reach.
Runoff and algae each carry roughly $1.1 billion — runoff in cost to states per the US EPA, algae across 22 states in the last decade. Two separate accountings of the same water problem arriving at the same order of magnitude is why water security sits on the risk register rather than on the annual maintenance line.
The conventional responses are disruptive by design. Chemical dosing treats the symptom on a schedule and adds its own load, while dredging means mobilization, dewatering, disposal and a water body out of service for the duration. Both are capital events that have to be justified in full up front.
- Eutrophication: over 2,300 lakes and rivers contaminated
- Hypoxia: without oxygen, aquatic life dies
- Polluted runoff: $1.1 billion cost to states (US EPA)
- Algae: more than $1.1 billion in cost across 22 states in the last decade
- Dredging takes the water body out of service and creates a disposal stream
- Deliberate contamination of water supply remains a live security threat
How it works
Treatment That Floats On Site
The Axbold Guardian is deployed in situ. It floats on the water body in a submersible enclosure at roughly 37 inches high and 82 pounds, and it treats where the problem is rather than moving the problem to where treatment lives. Nothing is added to the water except gas: air, oxygen or ozone.
Natural air nanobubbles activate aerobic growth for healthier water. Gas throughput is 171.9 LPM (45.4 GPM) at 90% mass transfer into the fluid, and by mass the platform delivers 222 grams per minute of air. Because the bubbles average 76 nm, carry an electrical charge and can stay in solution for months, oxygen reaches and remains in the lower column and at the sediment interface, which is where hypoxia does its damage. Coarse bubbles cannot do this; they rise and vent before they get there.
Where the load calls for oxidation rather than aeration, the same platform delivers up to 368 grams per minute of ozone, subject to generation capability, shredding toxins at the functional group level. Gas selection is a program decision made after the water is tested.
- In-situ floating deployment with no chemicals, no dredging and no dewatering
- 222 g/min air, or 245 g/min oxygen or 368 g/min ozone subject to generation capability
- 90% mass transfer into the fluid at 171.9 LPM (45.4 GPM) of gas
- 76 nm average bubble size, electrically charged, persistent in solution for months
- Portable and low-profile, needing less permitting, equipment and space
- Can be powered by solar panels at shoreline sites without service

What changes
The Water Body Stays Open
Mt. Woodson's Golf Course water healed in 80 days with 1 Axbold Nanobubbler on 1 of 5 ponds. Remediation that runs this way asks little of the site around it: no basin drawn down, no material trucked off for disposal, no access route cut for heavy plant. The work happens in the water rather than to the ground around it.
Because deployment is in situ and reversible, remediation stops being a single capital event. A unit set on one pond, one basin or one arm of a lagoon can be judged on data and then held, moved or added to, which is a different decision shape from a dredging campaign that has to be committed in full before anyone can see whether the water improves.
Axbold operates this as a service rather than a hardware sale. Emergent programs remediate active threats with heavy duty oxidation, Proactive programs hold standing risk down with persistent aquatic resilience work, and Embedded programs apply where the physical asset needs to sit on the balance sheet.
- No closure, no dewatering, no disposal stream to permit
- Operates on 2.7 kWh, solar-capable for remote shorelines
- Two moving parts and 90% less servicing time than conventional nanobubble units
- Quarterly checkup of one hour or less, 10 year useful life
- Deploy on one basin first, then scale on measured results
- IP68 Grade 316 stainless construction, floating in a submersible enclosure
Common questions
Is anything added to the water?
No chemicals are added. The only input is gas, either air, oxygen or ozone, infused into the water as ultra fine bubbles averaging 76 nm. There is no reagent to store, meter or account for, and nothing to dose on a schedule.
How does this compare with dredging?
It does not do the same job. Dredging physically removes accumulated material, including inert solids that no amount of oxidation will address, and if a basin has lost volume to silt that remains a dredging problem. Where the issue is organic sludge, algae and hypoxia, in-situ nanobubble oxidation restores oxygen to the lower column and sediment interface so aerobic processes can act on organics in place, without mobilization, dewatering, disposal or closure.
How long does it take to see a change?
It depends on the water. Mt. Woodson's Golf Course water healed in 80 days with 1 Axbold Nanobubbler on 1 of 5 ponds. Load, depth, temperature and sediment history all move that timeline, which is why Axbold programs include built-in testing and data services, so the trajectory is tracked against a baseline taken from your own water.
What does a deployed unit require in the field?
Very little attention, and the attention it does get is scheduled rather than reactive. Axbold monitors deployed systems proactively, so a field visit is a checkup on a unit already known to be running rather than a call-out after something has gone wrong. That is also what makes routine service time worth spending on the operator relationship instead of on the machine.
