What size particle does Size GAC filter correspond to?

The Size GAC (Granular Activated Carbon) filter corresponds to the size of activated carbon particles that are utilized in water treatment processes, including dialysis. The size ranges and mesh specifications reflect how finely the activated carbon is grinded and subsequently how effective it can be at adsorbing contaminants from the water.

The correct size designation of 12*40 mesh indicates that the granules of carbon pass through a 12 mesh screen but are retained by a 40 mesh screen. This size provides a balance between effective contaminant removal and water flow rate, ensuring that the filtration process is efficient while also allowing adequate water supply.

In contrast, the other options represent different particle sizes that may not align with the ideal filtration properties required in dialysis water treatment. The significance of using the appropriate mesh size lies in optimizing the filtration capability while minimizing pressure drop and flow resistance in the hemodialysis system. Therefore, the selection of 12*40 mesh for the Size GAC filter is crucial for the effective purification of water used in dialysis treatments.
