What equipment is needed to produce pure water?

Capping machine, leak detector (when the equipment output is large, the capping machine leaks, and the leak detector is responsible for re-capping the leaky barrels of the multi-capping machine), barrel brushing machine (external brush, internal brush and internal brush), full-automatic bottling machine (automatically transferring the barrels from the barrel washing station to the barrel washing station of the filling machine), lid washing machine (sterilizing the lids) and filling machine (collecting and washing barrels and filling) Bucket bagging machine (covered with plastic film on the finished purified water), stacker (relative to the production line with high output), find a vat or bottle, get some filtering equipment, things for filling, sealing and labeling, and packaging machinery.
