Our factory now needs to make a water filter with 1-2 levels of filtration and fully automatic backwashing. The first stage is ceramic filtration, the diameter of the ceramic ball is 0.8mm~1mm, and the filter height is 1.2 meters. The second stage is ceramic filtration, the diameter of the ceramic ball is 0.5mm~0.6mm, and the height is 0.9 meters. The conditions given are not very harsh, but the accuracy is 10~70 microns. Friends who hope to get expert guidance or have information in this regard can borrow it. Thank you all for your guidance.:loveliness:
