How much do You Know about Fine Bubble Disc Diffuser Aerator?
Fine Bubble Disc Diffuser Aerator is the necessary equipment for blast aeration and oxygenation. The selection of aeration equipment not only affects the effect of sewage biochemical treatment but also affects the land occupation, investment, and operation costs of the sewage field.
The structure and composition of the Fine Bubble Disc Diffuser Aerator
The structure type of the aerator is a disc type, which is composed of a microporous rubber membrane of the aeration disc, an aerator tray, etc., and is a high-efficiency oxygenation equipment. Rubber diaphragm material Silicone rubber.
The rubber diaphragm is disc-shaped and fits securely in its tray. There are micropores on the rubber membrane. The small I-shaped pores on the surface of the membrane and the arrangement of the openings in the spiral circle can not only keep the diameter of the bubbles discharged from the aerator within 1.0-2.0mm, but also make the aeration The resistance of the inflator is relatively reduced. Guaranteed to meet the requirements of oxygenation and the uniformity of gas distribution in the pool throughout the service range. The middle area of the rubber diaphragm is a non-opening area, which is specially designed as a self-closing structure. When the aeration is stopped, the air hole will be sealed and closed under the action of water pressure, effectively preventing the sewage from flowing back.
The function of the Fine Bubble Disc Diffuser Aerator
When the Fine Bubble Disc Diffuser Aerator is inflated with air, it is compressed by the gas, and the micropores on the rubber diaphragm expand by themselves to fill the pool with oxygen, and the air bubbles become smaller after the micropores are cut. The size of the bubbles can be adjusted with the increase or decrease of the air volume, to obtain a better oxygenation effect. The design of the sealing ring and O-ring around the rubber membrane ensures airtight performance between the rubber membrane and the fixing disc. When the air pressure increases, the sealing ability also increases, which can effectively prevent air leakage.
When the aeration stops, the aerator diaphragm has a self-closing function and is equipped with a check valve. The micropores on the rubber diaphragm will close by themselves, and the sewage will not enter the aerator system, and at the same time, it can prevent sludge clogged. After stopping the aeration for a long time, it can still aerate normally. The aerator and the air distribution pipe are connected through the thread in the special rubber adapter, which is convenient for the connection and disassembly of the aeration system and is convenient for maintenance and replacement. At the same time, the special rubber adapter has a sealing function after the thread is tightened to ensure a firm connection and a reliable seal.
The application field of the Fine Bubble Disc Diffuser Aerator
Fine Bubble Disc Diffuser Aerator is widely used in sewage treatment and purification processes. In these processes, a large amount of sludge needs to be aerated so that the organic matter can be decomposed by a large amount of oxidation and nitrification reactions. It can also be applied to the pre-aeration of the oxidation tank, the aeration process, or the oxidation and decomposition equipment of municipal and industrial sludge.
