Sedimentation Pond

Settling pond

       Principle

Tangential flow sedimentation is a water purification method that involves installing inclined pipes and plates at a 60-degree angle above the sludge suspension layer. This allows suspended particles, solid matter, or flocs formed after adding coagulants to the raw water to accumulate into a thin mud layer at the bottom side of the inclined pipes and plates. They then slide back to the sludge suspension layer under the force of gravity, eventually settling into the sludge collection basin. The sludge is discharged through a sludge drainage pipe for separate treatment or comprehensive utilization. The clear liquid gradually rises to the collection pipe and is discharged, either directly or reused.

       Application

The inclined tube inclined plate sedimentator can be used as a配套 equipment for processes like air flotation and clarification, and can also handle various wastewater types individually.

1. The electroplating wastewater contains a mixture of various metal ions, such as铭, copper, iron, zinc, and nickel, with removal rates exceeding 90% for each. Generally, the treated electroplating wastewater can meet the discharge standards.

2. Coal mine and ore processing wastewater treatment can reduce turbidity from 500-1500 mg/L to 5 mg/L.

3. Color removal efficiency for dyeing and bleaching wastewater reaches 70-90%, with a COD removal rate of 50-70%.

4. Removal of large amounts of organic matter from wastewater in industries such as leather and food processing, with a COD removal rate of 50-80% and a solid impurities removal rate exceeding 90%.

5. Chemical wastewater COD removal rate: 60-70%, color removal: 60-90%, suspended solids meet emission standards.

       Advantages

1. Simple structure, no fragile parts, durable, reduces maintenance.

2. Stable operation and user-friendly.

3. Low power consumption, energy-efficient.

4. Space-saving, low investment, rapid startup, and high efficiency.
