This series of water purification units integrates the essence of processes such as coagulation, sedimentation, sludge discharge, backwashing, water collection, and filtration, achieving fully automated operation without manual intervention. It is an essential water purification unit for realizing automated management in water treatment plants. When paired with our factory-produced ZJ-type automatic dosing devices and disinfection equipment, it can form a fully functional water purification station (plant). This series of water purification units not only has a wide range of applications and excellent treatment efficiency with superior effluent quality, but also features low self-consumption of water, reduced power consumption, and a compact footprint. It saves water, electricity, and labor, eliminating the need for auxiliary pumps and facilities, making it a new energy-saving product. **Scope of Application:** 1. Suitable for water treatment plants in rural towns, industrial, and mining enterprises using rivers, lakes, reservoirs, or other water sources with raw water turbidity less than 300 mg/L, serving as the main water purification treatment unit. 2. Particularly adaptable to lake water sources with low temperature, low turbidity, and seasonal algae. 3. Functions as a pretreatment device for high-purity water, beverage industry water, boiler feedwater, and other applications. 4. Used in various industrial circulating water systems to significantly improve the quality of recycled water. 5. Applied in reclaimed water treatment systems, using effluent from sewage treatment plants as the water source, for purification and reuse. **Main Features:** 1. Apart from managing the primary pump room and dosing system, the water purification unit itself automates processes including reaction, coagulation, sedimentation, sludge collection, sludge discharge, water collection, distribution, filtration, backwashing, and排污, requiring no manual operation. Operators only need to perform periodic water quality monitoring. 2. A high-concentration flocculation layer allows impurity particles in the raw water to fully collide, contact, and adsorb, adapting to various water temperatures and turbidity levels. It achieves high removal rates of impurities and offers algae removal functionality under year-round operating conditions. 3. A rapid sludge concentration chamber and an adjustable automatic sludge discharge system ensure timely removal of excess sludge and impurities, maintaining stable removal efficiency. 4. Efficient coagulation and sedimentation ensure consistently high-quality effluent. 5. An innovative water collection system with minimal head loss ensures uniform and effective water collection, improving volumetric efficiency and resulting in significant energy savings due to extremely low head loss. 6. Automation of the water purification system guarantees efficient filtration (effluent turbidity remains below 3 mg/L when raw water turbidity is under 3000 mg/L) and automatic backwashing, eliminating the need for additional backwash pumps or air compressors, thereby saving substantial capital investment and operational costs. 7. Low self-consumption of water, approximately <5%, actively contributes to conserving limited water resources. 8. Compact design reduces footprint by over 50% compared to conventional water purification structures, with a height of about 4.10 meters, allowing installation both indoors and outdoors. 9. Easily expandable, modifiable, reusable, relocatable, or adaptable for reuse in different locations.
