Management practices for micropollutant control in road runoff
Management practices for the control of micropollutants found in road runoff: from the “invention” of technical solutions to the “design” of innovative practices.

Flocculated sediments can reduce the size of sediment basin
Our results suggests that current sediment basin design could be modified when chemically-assisted settling is implemented, taking up less space and cost in construction sites.

Flocculated sediment and runoff quality improved by polyacrylamide
This study emphasises that the passive treatment of stormwater runoff using GPAM is a very effective method of flocculating sediments in turbid water.

Underwater sound mitigation of bubble curtains with different bubble sizes
Without mitigation measures, piling generates sound pressure levels which exceed the limit values for the sound exposure level and the peak level at distance 750 m. In this work, results from acoustical tests on bubble curtains as well as a first attempt for modeling the mitigation effect of bubble curtains are presented and discussed.

Effects of Clearflow products on trout
Our Clearflow products have been subjected to extensive research in Canada where it has been demonstrated there is little or no impact on river trout.

Noise reduction study - air bubble curtain in offshore piling
This paper describes a semi-analytical model that is used for the investigation of the sound reduction during marine piling when an air bubble curtain is placed around the pile.

Bubble Curtains attenuating noise pollution for harbour porpoises
This research shows bubble curtains dampen noise from offshore wind farm construction and reduce temporary habitat loss for harbour porpoises.

Research - evaluating oxygen transfer
This research shows results of the aeration systems we sell being uniformly excellent and producing some of the highest SOTE values observed.
