How to Operate the Dissolved Air Releaser Correctly - Wuxi Wanchuan Environmental Equipment Technology Co., Ltd.

Standard Operating Procedures for Dissolved Air Releasers

Proper operation and maintenance are essential for optimal performance and longevity of dissolved air flotation systems. Follow these guidelines to ensure efficient, safe, and reliable operation.

1

Pre-operation Preparation and Inspection

Before operation, thoroughly inspect the overall condition of the dissolved air releaser. Check for external damage and ensure all connections are tightly sealed to prevent leaks. Confirm upstream and downstream pipelines are unobstructed and remove any residual impurities. Verify compatibility between the dissolved air system and releaser, ensuring water quality meets requirements and is free of excessive corrosive substances or large particulate impurities.
2

Smooth Start-up and Operation

Follow a gradual approach during startup. Slowly introduce treated water until the releaser and pipelines are completely filled, then gradually turn on the air supply system. Maintain stable pressure during adjustment to avoid sudden changes. Observe bubble release status to ensure bubbles are fine and uniform. Monitor operating noise closely; if abnormalities occur, immediately stop operation, troubleshoot, then restart.
3

Operation Monitoring

Continuously monitor bubble morphology and water reaction during operation. If bubbles become coarser or unevenly distributed, promptly adjust air supply pressure or water flow rate. Regularly observe water condition around the releaser to prevent debris from affecting efficiency. Keep the operating environment clean to prevent external impurities from entering. Simultaneously, monitor the dissolved air system to ensure stable air supply and compliant water quality.
4

Shutdown and Subsequent Maintenance

Follow standard shutdown procedures: first shut off the air supply system, then stop water supply after pipeline pressure completely releases. After shutdown, promptly clean deposits and scale from the releaser's surface and interior. Inspect wear of key components like seals and release channels, replacing if necessary. Maintain accurate operation and maintenance records. For long-term shutdowns, take protective measures to prevent moisture and corrosion.

Visual Inspection

Regular visual checks of bubble size and distribution provide immediate feedback on system performance and help identify issues before they affect water treatment quality.

Parameter Adjustment

Fine-tuning air pressure and water flow rates based on observed bubble characteristics optimizes separation efficiency and minimizes energy consumption.

Preventive Maintenance

Regular cleaning and component inspection prevent scale buildup and mechanical failures, extending equipment lifespan and maintaining consistent performance.

Critical Safety Reminders

Always follow manufacturer guidelines and facility-specific safety protocols when operating dissolved air systems. Never bypass safety interlocks or operate equipment with known defects. Ensure proper personal protective equipment is worn during maintenance activities. Pressure systems require careful handling—always depressurize completely before opening any components. Document all maintenance activities and keep emergency contact information readily accessible.
