2. Project Core Pain Points and Requirements

2.1 Severe Raw Water Quality Issues

The raw water has multiple key indicators exceeding standards. High turbidity (13.3 NTU) and TSS (5 mg/l) cause water cloudiness; excessive nitrite (0.157 mg/l) and iron (0.76 mg/l) pose health risks for direct use or industrial applications. The low pH (6.06) makes the water acidic, which may corrode equipment pipelines.

2.2 Diverse Application Water Quality Requirements

The purified water needs to meet multiple standards (WHO, KEBS) and adapt to scenarios like medical production and semiconductor manufacturing. These fields require strict control of microorganisms (bacteria, viruses, coliforms), harmful substances (nitrite, ammonia), and aesthetic indicators (color, turbidity), demanding high filtration precision.

2.3 High Capacity and Stability Demands

With a required water output of 50 m³/H, the system must maintain continuous and stable operation to meet large-scale water needs. It should also adapt to potential raw water quality fluctuations without compromising purification efficiency, avoiding downtime impacts on production or use.

2.4 Logistics and Installation Adaptability

The equipment is shipped to Nairobi via CIF terms, requiring international transportation-standard packaging to prevent damage during transit. Additionally, the client may need flexible installation support—either self-installation with guidance or on-site engineer services—to suit local technical conditions.

2.5 Cost-Effective and Customizable Needs

The client expects a reasonable total cost (including freight) and supports customized design for specific water quality or on-site space requirements. Meanwhile, the system should have low long-term operation and maintenance costs, with easily replaceable consumables and simple maintenance procedures.

6. Frequently Asked Questions (FAQ)

6.1 Technical Questions

Q1: What is the service life of the ultrafiltration membrane, and how to maintain it?

A1: The PVC ultrafiltration membrane has a service life of 2-3 years under standard operation. Key maintenance measures:

• Regular backwashing: The system’s backwash pump (ZS70-40) automatically backwashes the membrane to remove surface impurities.
• Periodic chemical cleaning: Use the dedicated membrane washing device (cleaning tank + cleaning pump) for chemical cleaning every 3-6 months to restore membrane flux.
• Avoid overloading: Ensure the front-end precise filter is replaced in a timely manner (when pressure difference >0.2MPa) to prevent large particles from damaging the membrane.

Q2: How does the system adjust the pH of raw water (too acidic)?

A2: The system is equipped with a professional dosing system. According to the raw water pH test results (6.06), a specific neutralizing agent is added to adjust the pH to the standard range (6.5-8.5). The dosing amount is intelligently controlled by the PLC system, which automatically adjusts based on real-time pH monitoring data to ensure stable water quality.

Q3: Can the system adapt to changes in raw water quality and quantity?

A3: Yes. The system has strong adaptability:

• For raw water quality fluctuations (e.g., increased turbidity or nitrite content), the ultrafiltration membrane’s high-precision filtration ensures consistent purification effect.
• For water quantity changes, the frequency converter in the host control system adjusts the pump speed to match the water demand, maintaining stable water output without wasting energy.
• If raw water TDS exceeds 1000ppm, the system can be customized with a reverse osmosis (RO) module to enhance desalination capacity.

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: The total power of the system (including pumps and control system) is about 30Kw. Assuming 8 hours of operation per day and $0.12/kWh, the daily electricity cost is ~$28.8.
• Consumables Cost: PP filters (replaced monthly, ~$40/unit), neutralizing agents for the dosing system (~$25/day), and membrane replacement (amortized ~$15/day).
• Labor Cost: 1 operator suffices for daily monitoring (no full-time attendance required); daily labor cost ~$35 (varies by region).
• Total Daily Operating Cost: ~$108.8 (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:

1. Immediately contact Hella Water’s after-sales team with photos/videos of the malfunction and a detailed description of the issue.
2. The online engineer will provide remote troubleshooting guidance within 24 hours; most minor issues (e.g., parameter setting errors) can be resolved quickly.
3. For major defects (e.g., faulty pump, membrane damage due to quality issues), Hella Water will send free replacement parts or arrange on-site repair (client covers logistics for parts in some regions).
4. Note: The warranty does not cover damage caused by improper operation (e.g., failure to follow the instruction sheet) or natural disasters.

Q3: Is professional installation required, and what are the on-site requirements?

A3: – Installation Option 1 (Recommended): Self-installation with free support. The client receives an operation manual, installation video, and online engineer guidance—suitable for clients with basic industrial equipment installation experience.

• Installation Option 2: On-site engineer service. Hella Water can send engineers, but the client must cover visa, flights, accommodation, and labor costs—recommended for complex scenarios (e.g., integration with existing production lines).
• On-site Requirements: Flat and stable ground (supports system weight ~3000KG), 380V 3-phase 50Hz power supply, raw water inlet pipeline (matching DN100 interface), and drainage for backwashing wastewater.
