Case of TSMC Nanzih Science Park Wastewater Pit | Application of AS-type Float Switch Sewage Pump
In high-tech industries such as semiconductors and biotechnology, large volumes of process wastewater are generated daily. Taking TSMC’s Nanzih Science Park as an example, all wastewater is first collected in underground pits before undergoing subsequent treatment. To ensure stable pumping and system safety, the park has adopted the AS-type float switch sewage pump, combined with an intelligent water level control mechanism.
Automatic Start-Stop Design to Prevent Dry-Running Damage
The AS-type submersible pump is equipped with a float switch device that enables automatic start and stop according to the water level in the pit:
-
When the water level rises: the pump automatically starts, immediately transferring wastewater to the treatment system.
-
When the water level drops: the pump automatically stops, preventing dry-running and equipment damage.
This automation not only improves operational efficiency but also significantly reduces maintenance costs.
Stable Transfer to Meet Discharge Regulations
With the application of the AS-type float switch sewage pump, wastewater can be reliably and continuously delivered to the downstream treatment system, ensuring that the discharge process complies with environmental regulations. This guarantees a safer production environment for the park while demonstrating the company’s commitment to environmental responsibility.
