Ultrasonic algae control is a commercial technology that has been claimed to control the blooming of cyanobacteria, algae, and biofouling in lakes, and reservoirs, by using pulsed ultrasound. [ 6 ] [ 7 ] The duration of such treatment is supposed to take up to several months, depending on the water volume and algae species.
Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item.
Settling pond at the Bardney sugar factory in Lincolnshire, England Settling pond under construction, Blue Ribbon Mine, Alaska. A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater.
The largest dam removal project in U.S. history has freed the Klamath River, inspiring hope among Indigenous activists who pushed for rewilding to help save salmon. ... contributing to toxic algae ...
Bioreceptive Lightweight Concrete, Bartlett School of ArchitectureConcrete materials that are designed to encourage the growth of moss, lichens, and algae that reduce air pollution. Bioreceptivity is defined as "the ability of a material to be colonized by living organisms."
Typically, they are constructed with a concrete shell lined with polyvinyl chloride , boasting dimensions that vary from 10 to 100 meters in length and 1 to 10 meters in width, with depths ranging from 10 to 50 centimeters. William J. Oswald, was a figure in the field of environmental engineering, particularly known for his contributions to ...
The two organisms have evolved over millennia to work together, with corals providing shelter to algae, while the algae remove coral waste compounds and deliver energy and oxygen back to their hosts.
In most ponds both bacteria and algae are needed in order to maximize the decomposition of organic matter and the removal of other pollutants. [15] Algae produce oxygen (photosynthesis) and also consume oxygen (respiration), but they leave an excess of oxygen that can then be used by aerobic bacteria for respiration and for the processes of ...
