How to Clean Bottom Mud in DAF Dissolved Air Floatation

Proper preparation ensures safe and efficient cleaning operations while preventing accidents and environmental contamination.

• Shut down the flotation system and drain water from the tank
• Disconnect power supply and implement safety precautions
• Ensure all cleaning tools are in good working order
• Plan transportation and disposal routes for accumulated sludge

Select cleaning methods based on sludge thickness and hardness to ensure effective removal without damaging equipment.

• For soft and thin sludge: Loosen with shovel before suction transfer
• For hard or clumping sludge: Use high-pressure water jet to break up clumps
• Pay special attention to corners and pipe joints where sludge accumulates
• Avoid hard shoveling that could damage pool floor structure

Comprehensive inspection and proper disposal ensure system integrity and environmental compliance after cleaning.

• Conduct thorough inspection of pool floor for cracks and corrosion
• Promptly repair any problems found to prevent leaks
• Clean pool walls and equipment components to remove adhering dirt
• Clean and maintain tools for future use

Proactive maintenance planning minimizes sludge recurrence and ensures long-term system stability.

• Set appropriate cleaning cycle based on water quality and operational experience
• Optimize system operating parameters like influent flow rate and flocculant dosage
• Regularly check sludge removal device operating status
• Prevent long-term, difficult-to-remove sludge accumulation
