Dissolved Air Releaser Maintenance Procedures

Comprehensive maintenance approaches for addressing various types of blockages and ensuring optimal equipment performance

Physical Cleaning of Surface Impurities

In the early stages of clogging, suspended particles, silt, etc., in the water adhere to the releaser outlet or internal channels. To handle this, first stop the machine and depressurize, close the valves at both ends of the equipment, and disassemble the releaser casing and core components.

Use a high-pressure water gun to flush the clogged area, using the impact of the water flow to remove surface impurities
For small particles in the crevices, gently wipe them with a soft brush, avoiding scratching the inner wall of the equipment or the release hole
After cleaning, assemble the components and open the valves for a short trial run to observe if the water flow is smooth

Key Safety Consideration

Always ensure complete depressurization and valve closure before disassembly to prevent accidents or equipment damage during maintenance.

Biological Sludge Removal Treatment

Microbial growth in the water treatment system easily forms biological sludge, which adheres to the inside of the release device, causing blockages. Use an environmentally friendly biodegradable agent, dilute it according to the specified ratio, and inject it into the release device.

Let the solution soak for a period of time to allow the agent to fully decompose the sludge
After soaking, rinse repeatedly with clean water to completely remove the decomposed sludge residue
After treatment, a filter screen can be installed at the inlet to reduce the entry of microorganisms into the equipment
This preventive measure lowers the probability of sludge re-growth and extends maintenance intervals

Chemical Descaling to Dissolve Blockages

If the blockage is caused by hard scale such as calcium and magnesium scale or iron and manganese deposits, a targeted chemical descaling agent must be used. Select an acidic or chelating descaling agent according to the type of scale.

Strictly control the agent concentration and temperature to avoid corroding the equipment materials
Inject the descaling agent into the blockage area and soak until the scale is completely dissolved
During this process, gently shake the equipment to accelerate the reaction
After descaling, rinse the inside of the equipment with an alkaline neutralizing solution
Finally, rinse with clean water to remove any residual chemicals, preventing them from affecting subsequent operation

Chemical Handling Precautions

Always follow manufacturer guidelines for chemical concentration and exposure time, and use appropriate personal protective equipment during chemical cleaning procedures.

In-depth Disassembly and Inspection

When surface cleaning and chemical treatment are ineffective, the releaser must be completely disassembled and inspected. After disassembling all components, check the release port and internal channels for severe blockages or damage.

Clean stubborn blockages with specialized tools designed for the specific equipment configuration
If severely worn or corroded components are found, replace them with the same model parts immediately
During reassembly, ensure that the seals are properly installed to prevent water or air leakage
After inspection, perform a pressure test to confirm that the equipment is leak-free
Verify that the release function is normal before resuming regular operation
