english Pressurised DAF Equipment Installation Guide
Proper installation is crucial for optimal performance of Dissolved Air Flotation systems
Pre-Installation Preparation Phase 1
The installation begins with thorough pre-installation preparation to ensure the site meets all requirements.
- Evaluate the installation site for flatness and stability
- Ensure sufficient space for access and future maintenance
- Verify clear pathways for pipelines and electrical systems
- Inspect all equipment parts for damage or missing items
- Confirm components match manufacturer's specifications
An uneven surface can cause instability in the DAF tank and affect operational performance.
Core Components Installation Phase 2
The second step involves installing the core components of the DAF system.
DAF Tank Installation
Position the tank on a flat surface and secure it to prevent shifting. Use anchor bolts or stabilizing pads depending on size and weight.
Pressure Vessel Mounting
Mount in a location that allows easy connection to both the air compressor and the DAF tank.
Air Compressor Placement
Place in a well-ventilated area to ensure proper heat dissipation, with attention to reducing vibration.
Alignment is critical: Misalignment can disrupt water flow and bubble distribution.
System Connections & Debugging Phase 3
The third phase focuses on system connections and initial debugging.
Pipeline Connections
Connect pipelines between the DAF tank, pressure vessel, air compressor, and water inlet/outlet points.
Electrical Connections
Link the control panel to the compressor, pumps, and sensors. This work should be done by qualified personnel.
Preliminary Testing
Conduct a preliminary test: fill the system with water, activate the compressor to check air flow and pressure levels.
Seal integrity: All pipe joints must be sealed tightly to prevent leaks that can reduce pressure and compromise air dissolution.
Inspection & Acceptance Test Phase 4
The final step is a comprehensive inspection and acceptance test.
- Operate the entire system at normal conditions to evaluate performance
- Check for leaks in pipelines and joints
- Verify that bubbles form uniformly in the DAF tank
- Confirm control panel accurately monitors and adjusts parameters
- Review operation manuals with on-site staff
Once all checks pass and the system operates as expected, the installation process is considered complete.
