Hebei Xing Hong Kong Environmental Protection Equipment Co., Ltd. spirit of "virtue-oriented, business integrity, mutual benefit" principle struggled for years, since the establishment of the majority of users of praise. We sincerely welcome all walks of life to cooperate with us. Contact 0311 -85,236,167. Hu: 13831199587. Disc diffuser is used early, more mature aerator. The aerator is the beginning of the disc, and is corundum and ceramic materials (EDI disc of this material also has, according to a foreigner myself that quality is also good, but ridiculously expensive; basic need now also in Europe and America, and in the China could not even push). The main disadvantage of the disc below. 1, there is a dead zone of aeration (simple analysis, the entire bottom of the plate are), stirring performance as tube. 2, relative to waste pipe, the entire project cost is higher than the tube. 3, when no aeration, mud deposited directly on the surface of the disc is started again until the re-stirring up the mud should, be more expensive than the tube 30 to 40% of the energy (according to the foreigner that their two in the United States SBR process in a similar comparison, combined calculated conclusions). 4, layout density than tube, if you compare the small pond, aeration and is very large, so you can only use tube, because in this plane can not no matter how much cloth disk. Benefits: From GB provision, the disc head loss than the smaller tube, probably 1000pa; oxygen transfer efficiency compared to some tube to slightly a little bit. Compared with the disc, tubular aerator advantages are obvious: a stirring performance. Entire tube aerator is 360 degrees punch, there is no dead zone aeration. 2, saving the cost of part of the pipeline, the project cost to be significantly lower than the disc. 3, no aeration when the mud deposited on the tube surface only a small range of most middle (EDI this range is not perforated), a little to the side of one o'clock curvature is increased, the mud will not sink in it. Start again when the vibration pick up and quickly put the mud mixing. Therefore, SBR, CASS such processes, tubular advantage is very large. 4, in the aeration requires a great deal, the pool area is relatively small in the case, only the tube to meet the requirements. While the tube is greater than the pressure head aerator disc, oxygen transfer efficiency is slightly lower, but has been considered in the design of this point. Some more fabric through appropriate channels, to ensure that tube and the disc can achieve the same oxygen transfer efficiency, at least we are doing. And the aeration system pressure loss, primarily from depth pressure (generally 5 to 6 meters water depth), and that the pipe pressure drop 1000pa difference (the design has been equilibrated), almost negligible.
