List three unique properties of water a. First unique property: b. Second unique property: cAn aeration grid also helps the media mix in the tank and provides a continuous supply of oxygen. As with other aeration processes, the additional oxygen in the tank feeds the microorganisms so they can efficiently work on the organic matter in the water. A mesh sieve keeps the media inside the tank so they don’t escape.The zone of aeration is a zone under Earth's surface where air (and sometimes a mixture of air and water) fills in the openings between soil particles and rock material. In contrast to zone of saturation, zone of aeration is a portion in which the pore spaces are partially filled with air, not entirely, but with a mixture of air and water, where air and water fill the …Zone of aeration has less water held to the soil and rocks by capillarity force, whereas, zone of saturation are filled with water in all the rock spaces and its pores (Baldwin and McGuinness, 1963).
