The zone of aeration is the region between the earth's surface and the water table. The main components of this region are the soil and rocks. Their pores are at times partly filled with water and air, and aeration occurs when the air and water mix or come into close contact.Both the submersible pump and solenoid valve were installed with a time control switch and liquid level relay to realize automatic control. Two nano-microporous aeration discs (diameter: 8 cm) were placed at the bottom of the aerobic zone, and the aeration rate in the reactor was controlled to be 1.0 L/min by a gas flow meter.1. The zone of aeration is located immediately beneath the root-zone. The zone of saturation lies below the zone of aeration. 2. The soil and rocks in the zone of aeration have pores which are partially filled with water and air. The zone of saturation comprises rocks and soil whose pores are saturated with water. 3.Zone of Aeration. A zone below the land surface but above the water table, where pore spaces are filled mainly with air. Water that exists in the pore space in this zone is referred to as "soil moisture." The "capillary fringe," where capillary action draws moisture from the water table upwards, is considered to be part of the zone of aeration.Clarification: The intermediate zone is generally of small thickness and may be even absent in many cases.
