In recent years, Shuiyi has spearheaded significant initiatives, including the national 863 program "Integrated Technology for Advanced Water Treatment by Membrane Method", Zhejiang Province's "Leading Talents Program + X" research and development program, and Ningbo's "Science and Innovation 2025" major project. The company has actively participated in several major national and provincial scientific and technological projects. Shuiyi's research in separation membrane technology has garnered numerous accolades, such as the First Prize in Science and Technology Progress from Ningbo City and the Second Prize from the China Federation of Commerce in Science and Technology Progress.
At the core of its operations, Shuiyi focuses on technological innovation and is one of the select few manufacturers in the industry that possesses a complete range of membrane materials and products, including PVDF, PTFE, polyamide, PS, PES, among others. The company has developed comprehensive water treatment system solutions based on these technologies, encompassing Membrane Bioreactors (MBR), Ultrafiltration (UF), Submerged Membrane Filtration (SMF), Nanofiltration (NF), and Reverse Osmosis (RO). These products are extensively utilized for advanced treatment of municipal tap water, sewage standard discharge and reclaimed water reuse, preparation of industrial pure water, industrial reclaimed water reuse, and achieving zero discharge. Membrane-based regeneration restores water to its source. Shuiyi possesses comprehensive one-stop service capabilities that encompass materials, components, equipment, systems, and engineering, with the goal of becoming a global professional service provider for membrane liquid separation materials and products.
Product Description
Shuiyi Ultrafil™ Series (NIPS) RP-760V UF Membrane to Replace of Veolia ZW1500X UF Membranes
The Shuiyi Ultrafil™ (NIPS) Series Pressurized Ultrafiltration Membranes are manufactured using high-standard PVDF to form
homogeneous hollow fiber membranes. They offer exceptional removal efficiency for suspended solids, colloids, microorganisms,
bacteria, and viruses, ensuring consistent and reliable permeate water quality.
The standardized membrane modules adopt an outside-in filtration structure, which provides greater tolerance to variations in feed
water quality. The modules are available in a variety of models and are structurally compatible with mainstream products on the market,
allowing for seamless replacement. A modular skid-mounted design enables easy expansion and integration, with simple installation and low maintenance costs.
Our Advantages
Anti-Fouling & High Flux
Incorporating patented hydrophilic modification technology, the membrane exhibits excellent anti-fouling performance. It maintains high operational flux under low transmembrane pressure (TMP), resulting in a longer flux decay cycle during operation.
Excellent Permeate Quality
With a precise 0.03 μm nominal pore size and a homogeneous sponge-like structure, the membrane delivers high removal efficiency for colloidal particles, bacteria, and viruses-ensuring superior, stable, and reliable water quality.
Extended Service Life
Membrane fibers are sealed using a centrifugal potting process, producing a bubble free sealing layer and preventing glue creep. This structure withstands repeated, high intensity air-water scouring, reducing the risk of fiber breakage and ensuring long operational life.
Application Fields
The Shuiyi Ultrafil™ Series Pressurized Ultrafiltration Membranes feature high flux, a high degree of system integration, low capital investment, and a compact system footprint, making them suitable for projects with high permeate quality requirements
and limited space. They are widely applied in municipal drinking water, municipal reclaimed water, textile and dyeing wastewater, pulp and paper wastewater, basic chemical wastewater, mine water, steel industry water, PCB and electroplating wastewater, power plant water, and microelectronics water treatment.
