As water treatment projects continue to demand higher efficiency, lower energy consumption, and more stable effluent quality, ultrafiltration technology is becoming an increasingly important part of modern treatment systems. For municipal utilities and industrial users alike, selecting the right membrane product can directly affect operating costs, footprint, and long-term system reliability.
The Frere Lumina Immersion Ultrafiltration Membrane is designed to meet these challenges. Built with 1.35 mm high-flux PVDF composite membrane fibers and a high-density module design, the Frere Lumina series delivers high water production flux, stable permeate quality, strong anti-fouling performance, compact footprint, and reduced energy consumption. It is especially suitable for demanding applications such as reclaimed water reuse, advanced wastewater treatment, and municipal water supply.
One of the core strengths of the Frere Lumina series is its advanced membrane structure. The membrane fibers feature an average pore size of 0.03 μm, with a highly uniform pore distribution and high porosity. This design helps improve filtration precision while also enhancing fouling resistance and extending service life. Through optimized membrane material formulation and manufacturing process upgrades, the operating flux has been increased by 25%, allowing users to achieve higher productivity without sacrificing stability.
In addition, the membrane module adopts an ultra-fine inner-lined fiber design with a column-type configuration. This increases packing density by 50%, enabling more membrane area within the same installation space. For project owners, this translates into a smaller footprint, lower civil construction requirements, and reduced total project investment.
Water safety and effluent consistency are critical in both municipal and industrial applications. The Frere Lumina Immersion Ultrafiltration Membrane offers a bacterial retention rate greater than 5 Log and a virus retention rate greater than 4 Log, ensuring safe and stable produced water quality. This high level of retention makes the system suitable for applications where hygienic safety and reliable treatment performance are essential, including drinking water treatment and water reuse systems.
Because of its stable filtration performance, the Frere Lumina series can help treatment facilities meet strict water quality targets even under changing influent conditions.
Energy efficiency has become one of the biggest concerns in water treatment plant operation. A key advantage of the Frere Lumina series is its compatibility with unpowered siphon water production. In large-scale municipal water supply projects, this design allows water production without conventional powered suction, reducing operating energy consumption by more than 50%.
At the same time, the system can increase water production efficiency to 97%, making it a highly attractive choice for plants seeking both economic and environmental benefits. For operators focused on lifecycle cost control, this combination of low-pressure operation, energy savings, and high recovery offers significant value.
In real-world treatment systems, influent water quality and flow often fluctuate. The Frere Lumina series is engineered with strong resistance to shock loads in both water quality and water quantity, enabling it to handle more complex feed conditions than many conventional membrane products.
This makes it especially suitable for projects where influent conditions are unstable, where operating costs must be tightly controlled, or where large-scale treatment capacity is required. Its robust design supports long-term stable operation even in challenging environments.
Thanks to its high flux, fouling resistance, and flexible operating mode, the Frere Lumina Immersion Ultrafiltration Membrane can be widely used across many water treatment sectors, including:
Municipal drinking water treatment
Municipal reclaimed water reuse
Advanced sewage treatment
Textile printing and dyeing wastewater
Pulp and paper wastewater
Basic chemical wastewater
Mine water treatment
Steel industry water treatment
PCB and electroplating wastewater
Power industry water treatment
Semiconductor process water systems
This broad application range makes the Frere Lumina series a versatile solution for both public infrastructure projects and industrial water treatment systems.
As treatment standards rise and pressure grows to reduce both footprint and energy use, membrane systems must do more than simply filter water. They must deliver stable quality, high efficiency, lower operating cost, and long-term durability.
The Frere Lumina Immersion Ultrafiltration Membrane is built with these goals in mind. With its uniform membrane pore structure, high packing density, excellent bacteria and virus removal, and optional unpowered siphon operation, it provides a practical and forward-looking solution for modern water treatment challenges.
For utilities, engineering contractors, and industrial end users looking for a dependable ultrafiltration solution, Frere Lumina offers a strong balance of performance, economy, and sustainability.
