215mm Silicone Membrane Disc Diffuser Aerator For Wastewater Treatment

EPDM disc fine bubble air diffuser Dn215 oxygen microbubble aerator for Philippines is used to transfer air and with that oxygen into sewage or industrial wastewater. Oxygen is required by microorganisms in the water to break down the pollutants. Fine bubble diffusers produce a plethora of very small air bubbles which rise slowly from the floor of a wastewater treatment plant or sewage treatment plant aeration tank and provide substantial and efficient mass transfer of oxygen to the water. The oxygen, combined with the food source, sewage, allows the bacteria to produce enzymes which help break down the waste so that it can settle in the secondary clarifiers or be filtered by membranes. 

EPDM disc fine bubble air diffuser Dn215 oxygen microbubble aerator for Philippines adopts energy saving design, low installation cost, high reliability and excellent performance in intermittent and continuous aeration process fine.
1. Use imported material, good elasticity, long life time
2. Little bubble diameter, high oxygenate efficiency
3. Proof deposit,install convenient

When the air is closed, the center of the membrane falls on the orifice of the 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

Mechanical punching technology, there're over 5,500 perforations in Dn200 aerator, over 6,300 perforations in Dn215 aerator, over 9,000 perforations in Dn260 aerator,over 10,000 perforations in Dn330 aerator. Air deflector diameter is 0.5cm, the contact space with the membrane is 0.15cm, which make the opening rate of the membrane can reach 99.9% .At the same time, it can improve oxygenation capacity and oxygen utilization rate and reduce ventilation resistance.

A folded-concave structure with better sealing performance is adopted between the membrane and the bottom plate, which solves the disadvantage that the aeration membrane is easy to fall off when the air flow is too large. At the same time, a guide ring and six air guide grooves are added to the chassis support. Compared with other existing aeration devices, under the same operating load, the required aeration volume is greatly reduced, and the aeration is evenly distributed throughout the tank.

The professional machine is shaped by many processes, refined and cast, controlling every process and creating the perfect product.

Our EPDM membrane uses imported rubber, mixing with other materials,for example, antioxidants to let our membrane can service long time and resist acid and alkali. And the punching process made the holes dense and uniform, which can let aeration effect better.
