Product Description

Wastewater treatment EPDM membrane fine bubble diffuser

Product Description

 

1.The rubber washer and the corresponding groove are designed to ensure the air tightness of the product. Instead of using raw tape in the installation process, it is convenient to install, stable and reliable. 

2.Check valve structure. When operation stops, the membrane covers the structure under the action of rebound force and water depth pressure to prevent the backflow of mud water. 

3.Mechanical assembly production line, hot welding instead of adhesive process, to ensure adequate supply, uniform productquality, stable and reliable.

4.The spanner position is designed. Spanner is used to replace the traditional hand-twist installation, avoid membrane damage. And installation is convenient and reliable.

5.Six channel design, increase ventilation cross - sectional area, reduce resistance, efficient and energy - saving. The multiple positions of the membrane jointly bear air friction, reduce local wear and extend aerator membrane service life. Also, promote product 360 ° aeration, improve the product efficiency

Basic Info
--------------------------------------------------------------------------

EPDM Membrane disc fine bubble air diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications.

Disc diffuser adopts energy saving design, low installation cost, high reliability and excellent performance in intermittent and continuous aeration process.

Dense drilling is conducive to efficient oxygen transfer and utilization, in order to apply the aeration system specifications, can use different drilling mode to adjust the working pressure, such as different slot length, distance, the density of drilling.

Features:

1.Structure for preventing re-flux: When air closed,the center of membrane falls on the orifice of membrane tray,and the non-perforated area can cover the air release orifice, similar to a check valve, to prevent liquid from flowing back into the aeration system. In addition, according to the characteristics of sewage treatment process, an independent check valve has been developed, which can be used in combination with diaphragm check

2.Special punching technology: Over5,500 perforations in Dn200,over 6,300 perforations in Dn215,over 9,000 perforations in Dn260,over 10,000 perforations in Dn330. Air deflector diameter is 0.5cm, the contact space with membrane is 0.15cm, which make the opening rate of membrane can reach 99.9%.Also improve oxygenation capacity, oxygen utilzation rate and reduce ventilation resistance.

3.High pressure injection molding: The professional machine is shaped by many processes, refined and cast, controlling every process and creating the perfect product.

4.Compact structure uniform gas distribution: A folded-concave structure is better in sealing performance, which solves the disadvantage of easy tofalloff when the air flow is too large. Meanwhile,the chassis support add a guide ring and six air guide grooves. Compared with other existing aeration devices, under the same operating load, ours require aeration volume is greatly reduced,and the aeration is evenly distributed throughout the tank.
