I Put in air · Water body restoration
Lakes, streams and seas breathe again
Algal blooms and odour come from organic sediment on the bottom. Treat only the surface and it returns next year. Send air to the bottom as nanobubbles and the sediment breaks down; the bloom does not return.

Unit count and combination are sized from area, depth and inflow. Remote HMI and control panel are included. PRS750 specifications vary by module configuration and are provided on consultation.
Cheongna Lake Park configuration: 20 plasma modules + 2 × 10 L/min oxygen generators + 2 × 5 HP submerged nanobubble units (inflow 5,000 t/day). Daecheong trial: single 20 HP unit, 1,200 m² silt-curtain enclosure × 1 m depth, 2 t/min discharge.
Procedure
1 · Assessment
Review of area, depth, inflow and latest water-quality data. Site visit if needed.
2 · Design & contract
Unit count, layout, power, quotation. Route: PPS Innovative Product / technology agreement / patented-tech use agreement.
3 · Baseline & installation
Point-by-point water analysis before installation sets the baseline; then installation and commissioning.
4 · Unmanned operation & report
Continuous operation via remote HMI. Pre/post water-quality effect report delivered.
