Application Fields
The UFc90AL ultrafiltration membrane is tailored to address the evolving challenges in municipal water supply systems, where source water quality can fluctuate due to seasonal, industrial, or environmental factors. Its implementation can be found in:
Municipal Drinking Water Plants: Ensures turbidity control and microbial barrier protection in the pretreatment phase before final disinfection.
Surface Water Clarification: Efficiently removes particulate matter and organic pollutants from lakes, rivers, or reservoirs.
Groundwater Treatment: Ideal for regions with high iron, manganese, or suspended matter content.
Pretreatment for RO/NF Systems: Reduces SDI (Silt Density Index), extending the lifespan and performance of downstream membranes.
Decentralized Community Water Systems: Offers compact and scalable water purification solutions for rural or remote municipal supply projects.
With its reliable performance in high-throughput systems, the UFc90AL contributes significantly to safeguarding public health while lowering maintenance frequency and water treatment costs.
FAQ
Q1: What makes the UFc90AL suitable for municipal pretreatment compared to conventional filtration systems?
A1: The UFc90AL offers a significantly higher filtration precision than conventional sand or cartridge filters. Its 0.03 μm pore size effectively removes bacteria and fine particles, improving water safety and reducing chlorine demand in subsequent treatment stages.
Q2: Can the UFc90AL handle variable raw water conditions such as high turbidity or algae bloom?
A2: Yes, the membrane's outside-in structure and strong mechanical stability allow it to manage fluctuating water quality. Regular backwashing and chemical-enhanced cleaning help maintain flux and performance even in challenging seasonal conditions.
