Product Q&A

Q:What is the working principle of the sand filter?

Raw water enters the filter inlet and percolates through a thick layer of graded particles like sand or gravel. Suspended materials attach to the media, and clean water exits through filtration nozzles. When pressure differential reaches a preset value, the system triggers an automatic backwash cleaning process.

Q:How does the automatic cleaning process work?

In automatic installations, a pressure differential switch senses when the pressure across the filter reaches a maximum design value. It sends a signal to the controller to start backwashing, where pressurized water flows in reverse to suspend the filter bed and wash out dirt particles through the back-flush valve.

Q:What are the available control ways for the filter?

The filter supports three control ways: Differential Pressure, Time, and Manual operation, allowing users to choose the method that best fits their specific application requirements.

Q:What materials are used for the tank housing?

The tank housing is available in Carbon Steel or Stainless Steel. The tank thickness can be selected from 4mm, 6mm, or 8mm depending on the pressure requirements.

Q:What is the maximum working pressure?

The maximum working pressure is 10 Bar. The system operates within a minimum pressure of 0.15Mpa and a maximum pressure of 1.0Mpa.
