How to Extend the Service Life of DAF Dissolved Air Flotation

• 1. Regular Daily Maintenance

  Regularly check the operating status of all components, focusing on core components such as the dissolved air tank, releaser, and scraper. Promptly clean any blockages in the releaser to prevent poor flow from affecting equipment operation; regularly wipe the scraper blades, check the lubrication of transmission components, and add special lubricating oil as needed to prevent component wear and jamming. Meanwhile, regularly clean debris around the equipment and remove sediment from the tank to maintain a clean operating environment and reduce external factors that could damage the equipment.

• 2. Standardize and Control Operating Parameters

  Strictly follow the equipment operating procedures to set operating parameters, avoiding significant fluctuations in dissolved air pressure, water flow rate, and reagent dosage. Excessive dissolved air pressure can damage the inner wall of the tank, while insufficient pressure will affect the treatment effect and increase the burden on the equipment. Reagent dosage needs precise control; excessive dosage can cause corrosion and scaling of components, while insufficient dosage may lead to sludge buildup. Maintaining stable parameters reduces component fatigue and extends the overall service life of the equipment.

• 3. Enhance Influent Pretreatment

  Before influent enters the water, pretreatment is necessary to remove large impurities, hard particles, and corrosive substances. Pretreatment facilities such as screens and sedimentation tanks intercept impurities that may scratch the inner wall of the equipment, clog pipes and components, prevent hard particles from causing wear inside the equipment, and prevent corrosive substances from corroding the equipment materials. Pre-treatment before entering the flotation equipment can reduce equipment wear from the source and lower the failure rate.

• 4. Promptly Address Potential Faults

  If abnormal noises, vibrations, or unusual water output are detected during operation, the equipment must be stopped immediately for inspection. Identify the root cause of the fault and address it promptly to prevent minor issues from escalating into serious malfunctions. For vulnerable components, maintain a stockpile of suitable spare parts for rapid replacement in case of failure, minimizing equipment downtime. Conduct regular comprehensive maintenance and repairs, promptly addressing or replacing aging or corroded parts to ensure the equipment remains in good operating condition and extends its overall service life.
