Tubular Diffuser
Tubular Diffuser
Fine Bubble Tubular Diffusers are designed for maximal strength at minimum positive buoyancy. Although tubes are usually not as efficient as discs, tube diffusers are often the most economical choice of all diffusers, particularly for outer diameter of 90mm x 1m because of their relatively large size & high air capacity compared to disc diffusers. They require fewer header pipes, less support stands and less installation time than disc diffusers. The tube membranes are extruded from low extractable oil content EPDM polyurethane, silicone or nitrile. Perforations are available in 1 mm or 2 mm slit lengths and both saddles and nipples are designed to mount to US or metric dimension pipes. These have membrane life time up to 10 years in municipal waste water treatment plants, depending on waste water influent and operation condition.
