Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been a trusted manufacturer of advanced wastewater treatment solutions since 2015. Our 3-Stage Filtration Zero-Discharge Wastewater Recycling Unit with Automatic Backwash, IP65 Rated represents the pinnacle of efficient, sustainable water management. Designed for harsh industrial environments, this unit combines robust three-stage filtration with intelligent automatic backwash technology, ensuring uninterrupted operation and zero liquid discharge. With a factory spanning 10,000–30,000 square meters and annual export value between US$10 million and US$50 million, we deliver reliability and performance that meets global standards.
Our system is engineered to recycle wastewater into clean, reusable water, drastically reducing operational costs and environmental footprint. The IP65-rated enclosure protects sensitive electronics from dust and water jets, making it suitable for outdoor or wet-area installations. Whether your application involves industrial process water, cooling tower blowdown, or municipal sewage, this unit provides a dependable zero-discharge solution that aligns with stringent environmental regulations.
Key Features & Technical Specifications
- 3-Stage Filtration: Pre-filtration (gravel), primary filtration (fine sand), and polishing filtration (activated carbon) remove suspended solids, turbidity, and organic contaminants.
- Automatic Backwash: Intelligent control system triggers backwash based on time or differential pressure, ensuring continuous operation without manual intervention.
- Zero-Discharge Design: Closed-loop system recycles 100% of treated water back to the process, eliminating effluent discharge.
- IP65 Rated Enclosure: Dust-tight and protected against low-pressure water jets from any direction, ideal for demanding industrial settings.
- Modular Construction: Skid-mounted or containerized options available for easy transport and quick installation.
- Energy-Efficient: Low pressure drop design reduces pumping costs; backwash water is also recycled internally.
