Product Details
Ⅰ. Product Overview
U&D fine bubble disc diffuser has the features of U&D fine bubble membrane dffusers. lts support is made of ABS or PP+ fiberglass materials. Its standard membrane is EPDM membrane with precise pores favorable for high oxygen transfer and utilization. In order to adapt to different requirements of sizes for aeration system, different slit lengths, distances and pore opening density are used to regulate the working pressure. According to customerneeds, silicone rubber membrane and polyurethane membrane are also supplied as substitutes.

IV. Company introduction
In the field of design, materials, measuring and testmg.U&D has kept on innovating thanks to continuous investment in research and developmeat and the company's flexibility in design and production. This has brought us to a worldwide leading position in aeration technology and design
U&D has world’s most advanced membrane bubble systems totay.These novel aeration systems have been developed thanks to continuous research and development as well as active marketing, leading to U&D’s past and present leading position in the field of aeration technology.
Unique pore driling technology, which increases the surface of the unit significantly, and ensures a minion functional openings, giving air bubbles with a diameter of 0.8-1.9 mm guaranteeing a high aeration rate with large air volume circulation.Compared to ceramic (corundum) and traditional membrane aeration equipment. It's more than 50% more efficiency, making it one of the world ‘s most efficient and most advanced products.
U&D aeration systems uses the most flexible membranes design; high permeability for oxygen, operational adaptability, easy maintenance etc. show their outstanding charactertstics. far bener than traditional aeration products.
