The fully automated high-efficiency water purifier is an intelligent water treatment system developed by our company, integrating multiple processes including coagulation, sedimentation, filtration, and automatic backwashing. Featuring a compact integrated design, this product consolidates the multiple treatment units of traditional water plants into a single unit. Through an automated control system, it achieves end-to-end water treatment from raw water to qualified output, providing a compact, highly automated, and rapid-start solution for small-to-medium-scale water supply, industrial water use, and advanced wastewater purification.
- Structure and Working Principle
- Core structural composition
The equipment is an integrated skid-mounted steel structure, with functional zoning inside, primarily comprising:
- The mixing zone: Raw water undergoes rapid mixing and flocculation with automatically dosed coagulants (e.g., PAC), forming easily separable flocs.
- High-efficiency sedimentation/clarification zone: Typically employs inclined tube (plate) sedimentation technology or sludge suspension layer clarification technology to achieve rapid and efficient solid-liquid separation.
- Multi-stage filtration zone: The settled water enters the filtration unit, where it undergoes deep filtration through a media layer typically composed of quartz sand and anthracite, further removing residual suspended solids.
- Fully automated control system: The core management unit integrates a PLC controller, water quality sensors (e.g., turbidity meters), dosing pumps, and electric valves, enabling automated control of the entire process including dosing, sludge discharge, and backwashing.
- Working Principle
The equipment follows the classic water treatment process route of "chemical coagulation—precipitation clarification—deep filtration—automatic backwash", and is connected in series by the control system to operate continuously automatically.
- Automatic dosing and coagulation: The control unit automatically adjusts the metering pump based on raw water flow or quality signals, precisely adding coagulants and coagulant aids to ensure effective floc formation.
- Efficient sedimentation: Water enters the sedimentation zone, where flocs rapidly settle under shallow sedimentation conditions provided by inclined tubes (plates), and the clarified water flows into the next unit.
- Terminal filtration: Clear water passes through the filter media layer, where residual fine particles are retained, resulting in purified water with reduced turbidity.
- Intelligent backwashing: When the pressure differential or operating time of the filter unit reaches the preset threshold, the control system automatically initiates the backwashing program. It sequentially performs combined air-water backwashing on the sludge discharge zone and filter media, restoring equipment performance without manual intervention.
- Core Technical Features
- Integrated system with streamlined process: Combines multiple traditional tank functions (mixing, reaction, sedimentation, and filtration) into a single unit, ensuring seamless process flow. This design reduces both floor space requirements and civil engineering workloads.
- Fully automated operation: The entire process—from dosing and sludge discharge to filtration and backwashing—is controlled by a PLC program. It automatically adjusts to water quality and flow variations, enabling 24/7 unattended operation and reducing operator dependency.
- The effluent quality remains relatively stable: The multi-stage purification process ensures the equipment's ability to withstand fluctuations in raw water quality, with parameters such as effluent turbidity maintained at low levels.
- Highly efficient operation with rapid startup: Utilizing advanced sedimentation and filtration technologies, this system features high surface loading capacity and quick equipment activation, making it ideal for emergency or temporary projects requiring rapid water supply.
- Modular design with flexible scalability: These units can be configured as standard modules, allowing parallel combination to meet higher water treatment demands, with relatively simple expansion.
