The new type of flat membrane microporous diffuser is a technologically mature, reliable, energy-saving and efficient aerator, mainly used in the fields of municipal and industrial wastewater treatment. This product produces bubbles with small diameter, uniform diffusion, strong corrosion resistance, high oxygen utilization rate, low energy consumption, high efficienyy, and long service life.
Product features:
1.The traditional rubber diaphragm of the aerator has been replaced with a rubber diaphragm with extension compensation, which can freely rebound and avoid the tearing and detachment of the diaphragm caused by stress concentration. A reverse folding structure with good sealing performance is adopted between the diaphragm and the support plate, greatly extending the service life and effectively avoiding the phenomenon of diaphragm detachment.
2.The diaphragm adopts an inherent check valve design with a thickened center without holes. When the gas supply is turned off, under the action of water pressure and the elasticity of the diaphragm itself, the center of the diaphragm falls back on the hole of the support plate, and the unperforated area covers the air release hole, just like a check valve, which can prevent liquid from flowing back into the aeration system.
3.The diaphragm is made of imported ethylene propylene diene monomer (EPDM), which is anti-aging, corrosion resistant, acid and alkali resistant and durable.
The connection between the aerator and the pipeline adopts a unique connection method, which makes the pipeline connection more firm, has better sealing performance, and can effectively avoid the loosening of the connection parts caused by vibration during aeration work.
