Oxyvision has recently supplied 500 meter diffuser hoses for use as bubble curtain in canals in the Netherlands, with aim to separate sea water from freshwater during the period while the sluice is open for traffic. The method is to lower a boom with several diffuser hoses, which engage in periods when the water is stationary and boat traffic is taking place. Feedback indicates that the bubble curtain works as intended and that there is an urge to install adittional curtains in nearby canals.
