II. Full-Process Treatment Technology: Building a Closed-Loop Water Quality Assurance System

AAIWTP integrates four core treatment units: pre-treatment, ultrafiltration, reverse osmosis (for brackish water/seawater scenarios), and disinfection, forming a complete water purification and wastewater treatment process. It can be flexibly adjusted according to the type of industrial raw water (freshwater/brackish water/seawater) to ensure stable and controllable water quality.

1. Pre-Treatment: Building a Protective Barrier for Membrane Systems

Aiming at large particulate impurities and organic matter in industrial raw water, the pre-treatment unit adopts a combined process of coagulation + air flotation + sedimentation + oxidation + self-cleaning filter. This effectively reduces the pollution risk of subsequent membrane systems and extends the service life of membranes. The unit is integrated into a standard high-cube container, with a coagulation zone, sedimentation zone, and regulating tank arranged from right to left. The hydraulic retention times are 10 minutes, 20 minutes, and 15 minutes respectively. The treatment capacity of a single container reaches 2500 m³/d, and the inner and outer walls are coated with anti-corrosion coatings, making it suitable for complex industrial water quality environments.

2. Ultrafiltration: Precisely Capturing Microorganisms and Suspended Solids

The exclusive Grapheilm2 ultrafiltration membrane module of HAFE-FG Water Technologies is adopted, with core advantages directly meeting industrial needs:

• Filtration precision reaches 0.02 μm, which can remove almost all particles, colloids, bacteria, and viruses. The turbidity of the produced water is ≤ 0.1 NTU, providing high-quality inlet water for the subsequent reverse osmosis system;

• The membrane material is PVDF (Polyvinylidene Fluoride) combined with patented graphene hydrophilic modification technology, featuring strong anti-pollution capability and adaptability to scenarios with fluctuating industrial raw water quality;

• The outside-in filtration method is adopted, which can withstand high suspended solid concentration in the inlet water, reduce cleaning frequency, and lower operation & maintenance costs.

Technical Parameters of Model P Ultrafiltration Membrane Rack: Membrane area is 51 m² per module; a single membrane rack contains 50-64 modules; the height of the membrane rack is 2150 mm, and the length is 9.0-10.5 m; the flow rate of a single membrane rack is 125 m³/h; the flow rate of a single module for freshwater is 2.5 m³/h, and for seawater is 2 m³/h. Different industrial projects can match the treatment scale by increasing or decreasing the number of membrane racks. For example, the GAAIWTPF-10000 model requires 200 ultrafiltration membrane modules, while the GAAIWTPS-10000 model requires 256 modules.

3. Reverse Osmosis: Efficient Desalination for Brackish Water/Seawater Scenarios

To meet the brackish water/seawater treatment needs in industrial scenarios such as coastal areas and mining areas, AAIWTP is equipped with a high-pressure-resistant reverse osmosis system:

• Core equipment is integrated into a membrane rack made of SUS316L material; the high-pressure pipeline is made of duplex 2205 stainless steel (corrosion-resistant and high-pressure-resistant), and the low-pressure pipeline is made of UPVC (Unplasticized Polyvinyl Chloride), making it suitable for harsh industrial environments;

• The size of a single container is 12000 mm × 2300 mm × 2900 mm, containing 30 reverse osmosis membrane vessels (pressure rating: 300-1000 PSI). Each membrane vessel is equipped with 6 membrane elements, and the total number of membrane elements in a single container is 180. The salt removal rate is as high as 99%, and a multi-stage system can further improve the desalination rate.

The parameters of commonly used seawater desalination reverse osmosis membrane elements are shown in the table below (Test conditions: operating pressure 800 psi (5.52 MPa), 32000 mg/L NaCl solution, 25°C, pH=8, recovery rate 8%):

Table 2: Model, Rejection Rate & Membrane Area

Operating Limits: Maximum operating pressure 1200 psi (8.28 MPa), maximum raw water flow 75 GMP (17 m³/h), maximum temperature 45°C, maximum raw water SDI₁₅ (Silt Density Index) 5, maximum free chlorine concentration < 0.1 mg/L, maximum pressure drop per membrane element 15 psi (0.1 MPa), pH range for chemical cleaning 1-13, pH range for raw water during operation 2-11.

4. Disinfection: Ensuring the Safety of End Water Quality

As the final link in the treatment process, precise addition of disinfectants not only ensures that there are no pathogenic microorganisms in the produced water but also inhibits the secondary growth of bacteria and viruses in industrial water supply pipelines. It is suitable for industries with extremely high requirements for water quality safety, such as food and pharmaceuticals.

III. Flexible Model Configuration: Matching Diverse Needs of Mid-to-High-End Industry

AAIWTP takes a 40-foot standard container (12.0 m × 2.4 m × 2.4 m) as the basic unit, and is divided into Series F (for freshwater treatment) and Series S (for seawater treatment) according to the type of raw water. The number and functions of containers can be flexibly adjusted according to project scale and water quality characteristics (such as adding a raw water supply system, clean water tank, or dedicated treatment process for unconventional pollutants).
