High Efficient Wastewater Treatment Fine Bubble Disc Diffuser

12 inch fine bubble disc diffuser    9 inch fine bubble disc diffuser    8 inch fine bubble disc diffuser    6 inch coarse bubble disc diffuser  Membrane Disc 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. The membrane disc diffuser can be operated over a wide range of airflows with minimum maintenance for long term performance. Features   ♦ Low resistance loss                                     ♦ Highly Tear Resistant                ♦ Anti-clogging, anti-backflow ♦ Ageing-resistant, anti-corrosion                        ♦ High efficiency,energy-saving Typical Applications  Technical parameters Model HLBQ-150 HLBQ-215 HLBQ-260 HLBQ-300 Size 6 inch 8 inch 9 inch 12 inch Shape Disc Disc Disc Disc Type of Bubble Coarse Bubble Fine Bubble Fine Bubble Fine Bubble End Connection 1"NPT thread 3/4 ''NPT thread 3/4'' NPT thread 3/4 ''NPT thread Air Flow Rate(m3/hr) 6-8 1.8 3.0 4.2 MOC of Diffuser EPDM EPDM EPDM EPDM MOC of Diffuser support ABS ABS ABS ABS By considering the pressure balance, the best way of air pipe design is to connect all the pipes into a ring network. Inlet pipe valves should be set up each to conveniently adjust the volume of air. Air pipe designed velocity: main for 10-15 m/s; branch for 5 m/s. Installation height between surface of the diffuser and bottom of the ditch: 270 mm, 250 mm; the push plate type for 200 mm.
