*To Entrain means to draw in and transport.
This process begins with our Diffused Aeration style of aerators. we have a wide range of diffusers in which we offer both disc styled or tube styled membrane diffusers. The tube style diffuser membranes entrain water from 360° around the tube, this allows them to reach deeper water while the height of the diffuser base stops them from disturbing the fishery base. Disc style diffuser membranes entrain water from the top of the membrane up through the column.
During the summer, when the temperature heats up thermal stratification occurs. this is when within the fishery water layering occurs. The top layer of water will be warmer and oxygen rich whereas the bottom layer will be cooler and oxygen deficient, the transition layer which separates these two is called the thermocline. The difference in water density at the thermocline stops the two from mixing.
The diffused aeration systems that we offer pump air through the diffuser membranes. this is then able to travel to the fishery surface as millions of tiny bubbles. As the bubbles travel through the layers of thermal stratification they will entrain water, this water is transported to the surface where it will become naturally oxygenated.
Through the medium of aerating and circulating from the fishery bottom up, the toxic gasses previously trapped under the thermocline can escape, which will then provide a balanced habitat for aquatic life.
The aeration also creates aerobic conditions near the fishery bed where microbial processes can naturally break down nutrients which would otherwise be used in the production of noxious aquatic weeds and algae.
