Absolute Microbial Barrier — The High‑Flow, Chemical‑Free Purification Solution

Conventional disinfection methods (chlorination, UV) cannot fully remove viruses, and may produce harmful disinfection by‑products or fail against chlorine‑resistant microorganisms. Sand filtration alone is ineffective against colloids and large organic molecules.

Nollet Ultrafiltration (UF) Membrane provides a physical absolute barrier that completely removes pathogenic microorganisms (bacteria, viruses, algae), colloids, and high‑molecular‑weight organic matter without any chemical additives. Featuring a PVDF composite membrane with uniform pore size (<0.1 μm), it ensures consistently safe effluent regardless of feed water fluctuations. Ideal for river, reservoir, and mountain spring water purification, seawater desalination pretreatment, as well as industrial wastewater treatment and reuse.

Inside-out module

Suitable for water purification of rivers,reservoirs,mountain Springs, pretreatment seawater desalination, industrial wastewater, wastewater treatment, sewage reuse, etc.

MBR membrane module

This MBR membrane module features reinforced PVDF hollow fiber with a 0.02 μm pore size, ensuring superior filtration. Its proprietary sealing and cluster design prevent breakage and sludge clogging. Suitable for urban sewage, reclaimed water reuse, industrial wastewater, landfill leachate, etc., it delivers high flux and exceptional long-term durability.

Outside-in Membrane Module

It is used for water purification of rivers, reservoirs, mountain springs, pretreatment of seawater desalination, industrial wastewater treatment, sewage reuse, etc.

Submerged Membrane Module

It is used for water purification of rivers, mountain springs , reservoirs, and backwash wastewater from sand filter tanks,  industrial wastewater treatment, sewage reuse, etc.

Key Advantages of Nollet Ultrafiltration (UF) Membrane:

1.Absolute pathogen removal – Uniform pore size (<0.1 μm) and high microbial removal rate deliver superior microbiological safety (virus removal >99.99%, bacteria >99.9999%).

2.Fouling‑resistant & easy to clean – PVDF composite membrane chemistry reduces irreversible fouling, simplifying maintenance and extending service life.

3.No filament breakage – Proprietary bottom sealing technology prevents membrane filament damage during operation, ensuring long‑term integrity.

4.Broad application scope – Proven in drinking water (river/reservoir/spring water), RO pretreatment, and industrial wastewater treatment & reuse.

What application scenarios are Nollet’s UF membranes suitable for?

Nollet provides high-performance ultrafiltration water treatment solutions tailored to diverse water quality requirements and plant scales. Our ultrafiltration membrane filter technology is engineered for excellence across the following scenarios:

  • Municipal & Rural Water Supply:As a core ultrafiltration water filter component, it ensures the delivery of safe drinking water for both large-scale urban centers and rural development projects, effectively removing pathogens and turbidity.

  • Industrial Wastewater Treatment: Ideal for complex industrial effluents, our ultrafiltration system helps facilities meet stringent discharge standards while optimizing operational costs.

  • Municipal Sewage & Reclaimed Water Reuse: Nollet’s membranes facilitate the transition toward a circular water economy by purifying municipal sewage for non-potable reuse, such as irrigation or cooling processes.

  • Seawater Desalination Pretreatment:  To protect sensitive downstream equipment, our ultrafiltration membrane filter acts as a robust pretreatment barrier, significantly extending the lifespan of Reverse Osmosis (RO) systems in desalination plants.
