Complete standard process flow
Basic Standard Procedure (General for Surface Water and Reclaimed Water Reuse)
Raw water → Pre-treatment (self-cleaning filter/multi-media/activated carbon; mandatory when turbidity>10 NTU) → Ultrafiltration (UF) system → UF product tank → RO booster pump → 5 μm security filter → Reverse Osmosis (RO) system → RO product tank (pure water/reclaimed water)
Extended treatment pathway for highly polluted wastewater (dyeing/electroplating/chemical wastewater)
Raw water → Grid → Equalization tank → Coagulation/sedimentation/gas flotation → Softening (hardness removal) → Multi-media filtration → Ultrafiltration (UF) → Reverse Osmosis (RO) → Reclaimed water for reuse; RO concentrate can be further concentrated and reduced in volume using a Direct Thermal Reversal Oxidizer (DTRO).
The complete equipment set consists of five major components.
1. Pre-treatment unit (optional) 2. UF Ultrafiltration system 3. RO Reverse Osmosis system
4. Cleaning System (CIP Online Chemical Cleaning) 5. Automatic Control and Auxiliary Systems
Key advantages of the UF+R double-membrane method
1. RO offers exceptional protection: Compared to traditional sand filtration pretreatment, UF produces stable water quality without fluctuations, while RO membrane failure rates are reduced by over 40% and service life extended by 30%.
2. Compact footprint: For the same water volume, the UF system occupies only one-third of the space required by a traditional sand filtration system, and its modular撬装 design allows integration into containers.
3. High level of automation: The entire process is unmanned, featuring automatic backwashing, cleaning, and interlock protection systems, resulting in low labor costs.
4. Wide applicability to various water types: suitable for surface water, municipal reclaimed water, industrial wastewater, groundwater, and seawater desalination.
5. Stable and compliant water output: With dual-stage purification, the treated water meets standards for industrial circulating water, cleaning water, boiler makeup water, and pure water reuse.
