Frequently Asked Questions

Only water, air and oxygen. The reactive species generated by plasma are delivered into the water as nanobubbles and revert to water within minutes. No chemical agents are added at any stage. Systems are currently running at more than 20 sites nationwide; had there been fish mortality or similar problems, those operations could not have continued.

For the AnyNble-PRS750 running 24 hours a day, electricity comes to roughly KRW 1 million per month. Maintenance runs about 5–7% of the equipment purchase price per year, varying with site location and the number of units.

Winter operation is not a problem. While running, the water stays ice-free for roughly 250 m in front of the unit. Incheon Grand Park uses this to draw water for firefighting helicopters during winter wildfire season.Source: incheonin.com — coverage of winter firefighting-helicopter water intake at Incheon Grand Park (Korean)

From our earliest days we had to prove two things. First, that nanobubbles are actually produced — confirmed by test reports from national institutions. Second, what that does for water quality — and that we proved in the field, not the lab. We installed at sites where conventional methods had failed, demonstrated the improvement, and only then delivered. This is only possible if you can supply large volumes of nanobubbles reliably, 365 days a year.

Give us five things and we will size it. (1) Water volume. (2) Current water quality and inflow water quality. (3) Inflow rate — with volume this gives us retention time. (4) The site's main problem: algae, water grade, odour complaints. (5) Whether existing treatment facilities are in place.

Manufacturing takes 30–60 days depending on quantity. If the electrical work is ready, installation takes one to two days.

Songdo Central Park is a lake fed by West Sea seawater, and Jeju Ojo-ri is a coastal site. Operating both has confirmed that performance in seawater is in fact better.

Keeping bottom-layer dissolved oxygen above 10 mg/L structurally lowers mortality risk. Unlike surface aeration, nanobubbles carry oxygen all the way to the tank floor. Validated at olive-flounder farms in Jeju and Wando, with 50% better turbidity and a 30% higher survival rate. Installation is best completed before the summer heat arrives.
