6. Common Questions (FAQ)

6.1 What is the service life of the UF membrane in HLUF-120T?

Under normal operating conditions (with regular backwash and chemical cleaning), the PVC UF membrane has a service life of 3-5 years. The actual life depends on raw water quality and maintenance frequency. For replacement parts, refer to accessorysuopprting equipment.

6.2 How often does the machine require chemical cleaning?

Chemical cleaning frequency is determined by raw water pollution degree: generally once every 1-3 months. The machine is equipped with an automatic cleaning reminder function, and cleaning agents (citric acid & sodium hydroxide) are recommended for optimal membrane performance.

6.3 Is installation and maintenance support provided?

Yes. Hella Water provides a detailed user manual, installation video, and 7*24 online engineer support. On-site installation service is available upon request, with the client responsible for visa, flight tickets, accommodation, and labor costs of the engineer.

6.4 Can the ultrafiltration system handle raw water with higher TDS or turbidity?

Yes. For raw water with TDS ≤1000 ppm and turbidity ≤10 NTU, the HLUF-120T can achieve stable treatment after matching the appropriate pretreatment system. For high-turbidity or high-TDS raw water, we can customize a combined system of pre treatment filtration system and ultrafiltration.

6.5 What are the main application scenarios of the 120m³/H ultrafiltration machine?

It is widely used in: 1) Municipal water supply and secondary water supply; 2) Industrial process water (e.g., electronics, food, beverage); 3) Commercial water purification (e.g., direct drinking water station); 4) Wastewater reuse treatment; 5) High-quality drinking water production for communities or enterprises.

6.6 What is the difference between pure water machines and ultrapure water machines?

Pure water machines (TDS ≤10 ppm) meet potable water or general industrial water standards, while ultrapure water machines (TDS ≤0.1 ppm) adopt PLC integrated control, suitable for high-precision scenarios such as medical production, semiconductor manufacturing, and laboratory use. Both support customization based on demand.
