Crown Type Fine Bubble Air Aerator with EPDM Membrane In Black
Product Description
The surface of rubber diaphragm shall be smooth, flat, free of impurities, bubbles and cracks. The raw materials are mainly imported high-quality synthetic rubber with special ingredients, which are made by injection molding machine through scientific formula. It has the advantages of strong corrosion resistance, high strength and temperature resistance, and its service life can be more than 5-6 years.
ABS support part has the characteristics of high strength, high pressure bearing, good impact resistance, use temperature of - 30 ~ + 100 ℃, UV radiation resistance, acid, alkali and chemical corrosion resistance.

Installation
1. Installation of air distribution pipe
2. Installation of microporous aerator
3. Operation and maintenance
Remove all debris from the aeration tank before starting operation.
The time interval from the completion of aerator installation to trial operation and formal operation shall be as short as possible.
Painting, welding and other construction are prohibited in the aerobic tank installed with aerator but not yet in operation to avoid damage to rubber membrane of aerator.
Check the air switch and inject clean water, at least submerge the aerator 100 ~ 200mm. After a short time of air supply, close and cut off the air source. Check the air tightness of the aerator and air pipe network one by one. If there is air leakage due to poor sealing, air bubbles will appear here.
Check whether there is air leakage at the sealing places of all pipeline interfaces.
Under the condition of standard ventilation capacity of 1.8m3/h, check whether the aeration distribution is uniform, and the ventilation area of each microporous aerator is greater than 80%.
If it is not put into normal operation immediately after the completion of the test run inspection, the water level shall be raised to at least 1 m to submerge the aerator to prevent the adverse effects of ultraviolet rays and the possible extremely cold and hot weather temperature on the rubber membrane.
In the case of a long interval, considering the evaporation of water in the pool, the clear water should be supplemented in time. The aerator shall be aerated with standard air volume for at least ten minutes every day.
When the temperature is lower than 0o, the water level in the tank is about 1.5m ~ 2m to prevent the aerator from freezing.
