FAQ

What are the main components of the UF membrane system's operating costs?

The operating costs mainly consist of three parts: energy consumption, membrane cleaning chemicals, and spare parts replacement.
① Low energy consumption;
② Minimal chemical dosage;
③ Long replacement cycle of spare parts. The overall operating cost per ton of water is far lower than that of traditional processes.

Can UF membrane systems be customized according to actual needs?

Yes. Nollet's professional technical team will tailor-make intelligent membrane filtration water plant solutions based on customers' pain points, on-site working conditions (raw water quality, treatment capacity) and future development plans, covering membrane module specifications, system processes, and intelligent control modules. Meanwhile, we provide in-depth solution optimization and secondary development services.

Is the effluent quality of UF membrane filtration certified by authorities?

Nollet ultrafiltration (UF) membranes have obtained ISO 9001 Quality Management System Certification and Sanitary Safety Certification for Water-Contact Products (Water-Contact Product Approval). The effluent quality complies with relevant national and industry standards, and can be directly used as high-quality drinking water or industrial process water.

What if membrane modules malfunction or performance degrades?

1.Within the Warranty Period: Free repair or replacement is available for non-human damage (Nollet's comprehensive warranty policy). 2.After the Warranty Period: Preferential spare parts supply and maintenance services are provided with no hidden costs.

Is daily maintenance of the UF membrane system complicated?

It’s not complicated. The system is equipped with automatic backwashing and chemical cleaning functions, eliminating the need for frequent manual operations. Nollet provides detailed operation manuals and one-on-one on-site training. O&M personnel only need to master basic inspection skills (such as pressure and flow monitoring), and can enjoy lifetime technical support thereafter.

What is the service life of UF membranes, and how to extend it?

Under normal operation and standardized maintenance, the service life of Nollet ultrafiltration (UF) membranes exceeds 8 years.Key methods to extend service life:
① Regular cleaning;
② One free on-site inspection per year (a value-added service of Nollet);
③ Avoid over-temperature and over-pressure operation, and strictly follow the operating specifications.

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

It is widely applied to scenarios including municipal water supply, rural safe drinking water, industrial wastewater treatment, municipal sewage treatment, reclaimed water reuse, and seawater desalination pretreatment. Tailor-made system solutions can be provided based on the water plant scale and raw water quality.

What advantages do Nollet's UF membranes have over traditional water purification technologies?

1.Better Water Purification Quality: Meeting the direct drinking water standard.
2.Lower Operating Costs: Energy consumption is only 1/3 of that of traditional processes, and no large amount of chemical agents need to be added.
3.Intelligent and Convenient: A digital and intelligent control platform is built to monitor the membrane operation status in real time, supporting remote alarm and control.
4.Longer Service Life: Made of high-performance PVDF material with strong chemical stability, the service life can reach more than 8 years under normal maintenance.

What is the core working principle of ultrafiltration (UF) membranes?

Ultrafiltration (UF) membranes are a type of polymer separation material with a pore size ranging from 0.01 to 0.1 μm. Driven by pressure, they achieve physical sieving, which can efficiently retain impurities such as suspended solids, colloids, bacteria and viruses in water while preserving water molecules and beneficial minerals, thus realizing advanced water purification.

Customer Reviews

Having collaborated with Nollet for 3 years, we are impressed that the stability of its PVDF composite ultrafiltration membranes has exceeded expectations — the produced water quality consistently meets standards, and their 10-year service life is nearly double that of traditional membrane materials, significantly reducing our replacement costs. What’s even more convenient is the intelligent remote monitoring and control system: real-time equipment operation monitoring is achievable without additional staffing, boosting operational and maintenance efficiency by 60%. It truly deserves the reputation of an industry benchmark that participates in formulating national and industry standards.

Previously, the water quality in the village was turbid, and the treatment process was both energy-consuming and required frequent chemical dosing. After Nollet's eco-friendly membrane filtration equipment was put into operation, it achieves filtration through gravity-driven technology—no chemical addition is needed, and it can operate unattended. Finally, the villagers have access to safe and reliable drinking water. Their technical team provided on-site installation and commissioning throughout the entire process, and responds quickly to any subsequent issues. They truly deliver technology to the "last mile" of people's livelihood needs.

We chose Nollet as our core supplier based on three key factors: First, its strong technological strength—backed by over 30 invention patents, its membrane products boast internationally advanced performance, fully meeting the requirements of our high-end projects. Second, its sufficient production capacity—with an annual output of 3 million square meters, it perfectly matches the supply rhythm of our national projects. Third, its comprehensive services—providing end-to-end industrial chain support from solution design and engineering construction to post-operation maintenance. It has remained a reliable partner throughout our 5-year cooperation.

Having collaborated with Nollet for many years, our deepest impression is their dedication to technological innovation and professionalism in work. From the implementation of intellectual property management systems to the recognition as a "Specialized, Refined, Characteristic, and Innovative" enterprise, and further to the application for the first set of major technical equipment certification, their technological achievements are solid, the materials prepared are standardized, and their level of cooperation is extremely high. As a national high-tech enterprise, through continuous R&D investment and down-to-earth products, they have shown us the enterprise's pragmatic spirit and sense of responsibility.
