6. Common Questions (FAQ)
6.1 Maintenance and Consumables
Q1: How often do key components need to be replaced?A1: Precision filter elements (every 3-6 months), UF membranes (3-5 years, 10% annual replacement), and cleaning chemicals (replenished monthly). Replacement cycles depend on raw water quality. For replacement parts, visit [accessory supporting equipment].
Q2: What is the frequency of chemical cleaning?A2: Recommended every 3-6 months under normal operation. The frequency may increase if raw water turbidity or iron content is higher than average.
6.2 Warranty and After-Sales Service
Q1: What is covered under the 12-month warranty?A1: The warranty includes manufacturing defects in equipment (pumps, membranes, valves, control system). Consumables (filter elements, chemicals) and human-induced damages are excluded. Free online technical support is provided for life.
Q2: Can Hella Water provide on-site service in Uruguay?A2: Yes. On-site installation, maintenance, and troubleshooting services are available. The customer bears travel, accommodation, and labor costs for engineers.
6.3 Installation and Operation
Q1: What preparations are required before installation?A1: The customer needs to prepare a flat installation site (≥100㎡), stable power supply (380V/50Hz 3-phase), raw water inlet pipeline, and purified water storage tank.
Q2: How does the system adapt to raw water quality fluctuations?A2: The PLC system adjusts backwashing frequency and pump speed in real-time to handle fluctuations in turbidity and TSS, ensuring consistent water quality.
6.4 System Performance
Q1: What is the maximum raw water turbidity the system can handle?A1: The system is designed for raw water turbidity <20 NTU. For turbidity >20 NTU, a pre-sedimentation tank is recommended to protect the UF membranes.
Q2: Can the system be expanded for higher capacity?A2: Yes. The modular design allows adding additional 200m³/h modules to increase total capacity (e.g., 1200m³/h, 1500m³/h) based on future needs.
