Silicon Ingot and Wafer Slicing​

    In semiconductor and solar cell manufacturing, silicon wafers are sliced from ingots using abrasive techniques that generate large volumes of fine particulate-laden cooling water. This slurry must be purified before the cooling liquid can be recirculated. JOECHRE filters are ideal for this task, offering two proven solutions: precoat filtration with slurry and dry discharge, or direct filtration on sub-micron membranes for finer separation. Both methods produce crystal-clear filtrate and support reliable cake discharge, even at very low cake thicknesses. The fully automated, enclosed system ensures consistent performance and minimal operator involvement. JOECHRE filters help reduce waste, lower operating costs, and support more sustainable wafer slicing operations through efficient coolant recycling.​
