Application scenarios：
The skimming pipe is mainly used in structures such as grit chambers, sedimentation tanks, and equalization tanks in wastewater treatment plants. Through the skimming pipe (or skimming weir) arranged on the water surface, it collects floating scum, grease, foam, and light suspended solids and guides them into the scum collection trough, achieving continuous and stable skimming operation and improving effluent quality.
Structure&Principle：
Structure: It is mainly composed of the skimming pipe body (steel pipe or stainless steel pipe), an adjustment mechanism (lifting screw or float), a scum collection trough, a support frame, and seals. The skimming pipe is provided with notches or slits at specific angles for collecting scum.
Principle: The skimming pipe maintains its notches flush with the water surface through the adjustment mechanism. As the wastewater flows in the tank, the scum floats along with the water flow to the skimming pipe, enters the pipe through the notches, and flows into the scum collection trough by gravity or water flow 动力，thereby achieving continuous skimming.
Main Features：
1. Adopts worm gear (or eccentric wheel mechanism) transmission for smooth and labor saving operation.
2. Straight mouth and uniform overflow.
3. Can adapt to slight changes in liquid level without affecting usage.
4. Simple structure, easy installation and operation.
