As we all know,hollow fiber uf membrane uses epoxy resin glue to encapsulate the hollow short fibers in a cylindrical descriptor. The poured epoxy resin is dried and laser cut on both sides of the cylindrical descriptor to form a shell-and-tube heat exchanger. And other structures. Uf membrane module can be produced by refitting a cap on each side of this structure. The inlet pipe and concentrated water part of ro uf membrane are generally above the caps on both sides of the module, and the water production part on the inner wall of the cylinder is called the axial water production structure, and the sealing cap is also called the radial water production structure. At present, the most popular large, medium and small components are mostly radial water production structures.
The assembly of uf membrane module can be divided into two types: lying type and standing type. The flat membrane stack has a fast processing speed and a small footprint. It is suitable for large and medium-sized or super large-scale operating system software. However, choosing this method can facilitate the accumulation of the lower half of the membrane surface and is not suitable for cleaning with membrane modules. In a practical sense, the horizontal type uses the operating cost to obtain the indoor space cost, while the standing type uses the indoor space cost to obtain the operating cost. When selecting the assembly method of ultrafiltration components, the natural environment and construction scale of the actual project should be considered.
The system arrangement of uf membrane module also has two sorting modes: series and series. In the special high mortar consistency material liquid treatment industry, it is stipulated that the total flow rate of membrane surface washing is large, the output of a single component is small, the utilization rate is low, and the component loss is small, and it can form a series structure. In the sewage treatment industry, the mortar consistency of the source water is low, the output of a single ro uf membrane is large, the utilization rate is high, and the loss of membrane modules is large. A dry series structure will cause the water production rate of the rear module to be greatly reduced, so choose A simple tandem structure of dry film modules was created.
