Filling Method of Ceramsite Filter Bed

The filling quality of ceramsite filter media directly affects the filtration effect and operating cycle.

Preparation before filling

Check the tank for leaks, ensure filter heads and plates are intact, and remove debris.

Check that the ceramsite particle size and gradation meet design requirements.

Support layer laying (if necessary)

Lay in layers according to particle size from largest to smallest:

Level each layer before laying the next to prevent mixing.

Ceramic Aluminum Filter Media Filling

Wet Filling (Recommended): Fill the tank with water to a depth of 300-500mm, then slowly pour the ceramic granules into the water, utilizing the buffering effect of the water to reduce breakage. Level the granules every 300-500mm.

Dry Filling: Pour directly in, but the filling drop must be ≤1m to prevent breakage.

Post-Filling Treatment

Backwashing to remove debris and dust generated during filling (air washing → combined air-water washing → water washing)

Check the filter bed height and replenish if necessary.

Summary

The filling of ceramsite filter media can be summarized as follows: the support layer is laid in stages, the filter media is filled using a wet method, each layer is leveled after filling, and backwashing is performed after filling. Wet filling reduces breakage and is the recommended standard method. Proper filling is the foundation for the long-term stable operation of the filter.
