First, fill the filter system with sterile water and then use deoxygenated water instead of sterile water.
The second step, adjust the two loops, pre-coating, replace the pre-coated water with the wine to be filtered, and filter.
The third step is to clean the unloading soil, use a separate pipe grid for backwashing, scrubbing through the wash ball, and flush the lines.
After the last filtration, the whole system is sterilized. The overall system operation is more convenient.
