Immersion ultrafiltration equipment

main features

The hollow fiber membrane adopts PET woven mesh tube as the inner lining, embedded in the inner wall of the membrane fibers and firmly composite with PVDF functional layer. The single fiber fracture strength is above 400N, and the tensile strength is>100.0MPa. This special composite structure completely solves the problems of elongation deformation, fiber breakage, and easy damage and falling of functional layers of hollow fiber membrane fibers, ensuring the long-term stability of water quality.

The permanently hydrophilic modified PVDF material and high porosity membrane structure endow the membrane filaments with extremely strong water permeability, with a porosity of>60%. The pure water flux can reach over 300L/m2/h-0.02MPa (TMP), while the conventional ultrafiltration design flux can reach 10-40L/m2/h-0.03MPa (TMP). The designed flux is higher than that of similar imported products, and is about twice the designed flux of domestic ultrafiltration equipment.

The filtration accuracy of ultrafiltration equipment is not less than 0.1um, and the turbidity of ultrafiltration produced water is less than 0.3NTU, SDI<4， Meet the requirements for direct entry into reverse osmosis technology; The use of submerged ultrafiltration equipment can replace the process of "secondary sedimentation tank+coagulation sedimentation+sand filtration+external ultrafiltration", simplifying the deep treatment process of sewage
