FBS have a solution in the form of the bubble curtain. Using a synthetic sintered tube fed by low-pressure air supply, a uniform rising curtain of small bubbles can be created in the water column. This can provide a solution for: Prevention of silt accumulation Debris, weed, leaf, fish and oil deflection at cooling and raw water intakes Flotsam deflection at marina and harbour entrances Inshore oil-spill containment around tanker berths etc Lake and pond aeration Air is supplied by an economical low-pressure blower, for low running costs and maintenance, and high reliability.
