1. Breaking the Water Crisis
Did you know? Bahrain is an island nation located in a desert region, with scarce natural water resources. It heavily relies on seawater desalination and groundwater. As a water-intensive service industry, car washing faces operational cost pressures and environmental regulatory challenges. What if wastewater could be transformed into a stable and reliable "second water source"?
2. Core Technical Process Explained
First Stage: Oil and Grease Pretreatment
Using Yimei's DNF system, micro-bubbles efficiently remove suspended solids, oils, and detergent foam. This reduces the biochemical load in subsequent stages and adapts to the fluctuating nature of car wash wastewater.
Second Stage: Biological Purification and Dissolution
Utilizing the MBBR process, microbial films on suspended biological carriers degrade dissolved organic matter (BOD/COD). This method ensures high efficiency, strong impact resistance, and minimal sludge production, making it ideal for small to medium-scale wastewater treatment.
Third Stage: Deep Purification
Through sand filtration, precision filtration, and activated carbon adsorption, residual turbidity, color, and trace pollutants are removed. This guarantees clear, transparent, odorless, and tasteless effluent, meeting high-quality reuse standards.
**Process Unit | Core Functions | Target Wastewater Characteristics** |
DAF (Dissolved Air Flotation) | Removal of oils, grease, colloids, and suspended solids (SS) | Wastewater containing oils, fats, and fine particles that are difficult to settle naturally (e.g., food scraps, hair, fibers). |
MBBR (Moving Bed Biofilm Reactor) | Degradation of biodegradable organic matter (BOD/COD) | Medium-strength organic wastewater (e.g., COD 500-2000 mg/L) requiring stable, efficient, and shock-resistant biological treatment. |
Filter (Filtration) | Removal of suspended solids, turbidity, and color | Final "polishing" treatment to protect downstream processes (e.g., reverse osmosis) or meet strict effluent clarity/visual standards. |
3. Other Applications of This Model
This solution is not limited to car washes and can also be applied in:
Vehicle repair shops
Meat and seafood processing plants
Dairy factories
Breweries and beverage production
Vegetable oil refining and processing
Large restaurants and the hospitality industry
4. Yimei’s Integrated Solution: More Than Just Technology
Yimei’s combined process is not merely a technical solution—it represents a revolution in water resource management thinking. It proves that even in the most water-scarce regions, sustainable water cycling paths can be created through technology and ingenuity, giving every drop of water a new life.
