2. Project Core Pain Points and Requirements

2.1 Severe Raw Water Contamination
The raw water has 18 out of 39 tested parameters exceeding standards, including high concentrations of heavy metals (mercury, cadmium), toxic organics (benzene, toluene, xylene), and harmful substances (cyanide, nitrite). Direct use will cause equipment corrosion, product quality issues, and environmental hazards—critical for sensitive fields like medical production and semiconductors.
2.2 High Purity Demand for Target Water
Industrial scenarios such as semiconductor manufacturing and boiler water supply require ultra-low impurity levels. For example, boiler water needs minimal scaling ions (chloride, sulfate), while medical production demands strict control of toxic organics and heavy metals. The system must achieve 99.5% desalination and comprehensive removal of pollutants.
2.3 Stable and Efficient Operation Requirements
The system needs to adapt to potential raw water quality fluctuations while maintaining consistent output. It must operate continuously with low maintenance, as downtime in industrial production (e.g., semiconductor fabrication) leads to significant economic losses.
2.4 Compliance with Local Standards and Logistics Needs
The treated water must meet San Antonio’s local industrial water standards. Additionally, the equipment requires international transportation-friendly packaging to avoid damage during transit, with a short lead time (15 days) to meet urgent project timelines.
2.5 Cost-Effective Customization
Customers may have specific water quality or installation space requirements. The solution needs to support flexible customization without excessive cost increases, while ensuring long-term operational cost efficiency (e.g., low chemical consumption, long membrane lifespan).

6. Frequently Asked Questions (FAQ)
6.1 Technical Questions
Q1: What is the service life of core components like UF and RO membranes, and how to maintain them?
A1: – UF Membrane: Service life of 2-3 years; maintain by regular backwashing (automatic function included) and chemical cleaning every 3-6 months.
- RO Membrane: Service life of 2-3 years (99.5% desalination rate retention); key maintenance: control inlet water SDI <5 and residual chlorine <0.1mg/L, replace precision filter (5μm PP cotton) when pressure difference >0.2MPa, and conduct regular membrane cleaning (CIP cleaning system supported).
- Hella Water provides a detailed maintenance manual and online guidance to extend component life.
Q2: Can the system adapt to fluctuations in raw water quality?
A2: Yes. The system is designed with multiple adaptive features:
- The pre-treatment stage (quartz sand + activated carbon) effectively handles turbidity and residual chlorine fluctuations.
- The anti-scaling dosing system automatically adjusts chemical dosage based on water hardness, preventing scaling under varying conditions.
- The RO system’s high-pressure pump with pressure protection adapts to inlet pressure changes, ensuring stable operation even if raw water TDS exceeds 1000mg/L (with membrane model adjustment).
Q3: What safety protection measures does the system have?
A3: The system is equipped with comprehensive protection devices:
- Pressure Protection: High/low pressure switches (shutdown/alarm for abnormal pressure).
- Electrical Protection: Overload protection, high/low voltage switches.
- Water Quality Protection: Conductivity alarm (triggers if treated water quality fails).
- Mechanical Protection: Safety valve, liquid level alarm (prevents dry running of pumps).
- Membrane Protection: Precision filter (prevents large particles from damaging membranes), residual chlorine control (avoids oxidation).
6.2 Operational and Economic Questions
Q1: What is the daily operating cost of the system?
A1: Daily operating costs mainly include three parts:
- Energy Cost: Total power 52Kw; assuming 8 hours of operation per day and $0.15/kWh, daily electricity cost is ~$62.4.
- Consumables Cost: PP cotton filter (replaced monthly, ~$50/unit), chemicals for dosing system (~$30/day), membrane replacement (amortized ~$20/day).
- Labor Cost: 1 operator suffices for daily monitoring (no full-time attendance required); daily labor cost ~$40 (varies by region).
- Total Daily Operating Cost: ~$152.4 (varies by local energy and labor prices).
Q2: What should I do if the system malfunctions during the warranty period?
A2: Follow these steps for warranty claims:
- Contact Hella Water’s after-sales team immediately with photos/videos of the malfunction and a detailed description.
- The online engineer will provide troubleshooting guidance within 24 hours; minor issues are resolved via remote support.
- For major defects (e.g., faulty pump, membrane damage due to quality issues), Hella Water will send replacement parts for free or arrange on-site repair (client covers logistics for parts in some regions).
- Ensure proper usage per the instruction sheet—warranty does not cover damage from improper operation.
Q3: Is on-site installation necessary, and what are the requirements?
A3: – Installation Option 1 (Recommended): Self-installation with free support (manual, video, online engineer). Suitable for clients with basic industrial equipment installation experience.
- Installation Option 2: On-site engineer service (client pays visa, flights, accommodation, and labor costs). Recommended for complex scenarios (e.g., integration with existing production lines).
- Installation Requirements: Flat and stable ground (supports system weight ~2000KG), 380V 3-phase 50Hz power supply, raw water inlet pipeline (matching pump interface), and drainage for backwashing wastewater.
