Impurities and contaminants carried by influent water are a major source of pipeline blockage, and proper pretreatment is necessary to reduce the risk.

• Install suitable filtration devices at the inlet to intercept large particles and fibrous materials
• Use pre-processing with separation or flocculation for water containing oil or high concentrations of suspended solids
• Reduce the content of easily deposited materials to minimize impurity accumulation

Regular cleaning is a key measure to prevent pipe blockages, and a reasonable cleaning cycle and process should be established.

• Use backwashing with high-pressure water to flush pipe walls and remove adherent dirt
• Apply chemical cleaning for stubborn blockages, selecting appropriate cleaning agents
• Regularly check seals of pipe joints to prevent leakage and localized accumulation

Proper operating parameters can reduce material accumulation within pipes and minimize blockage likelihood.

• Control inlet flow rate and velocity to avoid sedimentation or excessive wear
• Adjust dissolved air system parameters for uniform and stable bubble release
• Precisely control flocculant dosage to avoid excessively large flocs

The selection of pipe materials and specifications is crucial for preventing blockages.

• Choose corrosion-resistant, smooth-surfaced pipe materials to minimize adhesion
• Design pipe specifications to ensure diameter matches flow rate requirements
• Minimize unnecessary elbows and diameter changes in pipe design
