Bubble Tubing® Application

Litter & Weed Control Bubble Curtains

Keeping water spaces clean and reducing invasive plant spread using Bubble Curtains.

Floating litter, plastics and drifting weed can quickly degrade the quality and amenity of lakes, reservoirs, rivers, canals and harbours.

Bubble Curtains, delivered as a Bubble Tubing® application, provide a proven way to corral and deflect debris.

The rising plume of microbubbles generates vertical flow and a gentle surface barrier that steers litter and weed towards collection points, helping to improve water quality, limit invasive spread and protect high-value urban and natural water spaces.

The curtain is permeable, so it does not inhibit navigation and allows fish passage.

Systems use self-weighted Bubble Tubing® that is simple to deploy from bank or vessel and can be configured for temporary tasks or long-term operation.
Layouts are versatile, straight runs, arcs or full enclosures, and connect to silent or renewable-powered compressor options for sensitive sites.
ISO 9001-engineered diffuser technology delivers reliable, low-maintenance performance with self-cleaning perforations, low energy demand, robust chemical/UV/salinity resistance and a 5-year warranty, safe for aquatic fauna and flora.
