Wastewater treatment EPDM membrane fine bubble diffuserProduct
Description 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 check2.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.Disk specificationφ215mmφ260mmφ300mmSize8 inch9 inch12
