2, water purification station did not post the sampling point number
3, purified water needs to be added to the water point number; the first floor of the purified water tank above the pipeline without the flow direction marking;
4, the purified water physicochemical testing records: non-volatile matter test weighing without the original printout; conductivity test should be added to the unit;
5, purified water system from the EDI is purified water, but the site of the pipeline and valves, water pumps, pressure gauges are not in accordance with the standards of purified water, there is a risk of contamination.
6, purified water verification did not verify whether the action of the automatic solenoid valve is accurate.
7, the installation of purified water online conductivity monitoring without drawings.
8, purified water without management design drawings, piping non-hygienic connection, no daily monitoring, piping design is not conducive to sampling. 9, purified water irrigation and welding does not meet the requirements,
10, purified water without sampling records; purified water back to the water should be installed at the flowmeter
11, the purified water system needs to be sent to the general, the general back to the tanks, the furthest point of water use a weekly full inspection, the remaining Monthly full inspection of water points
12, the validation of the purified water system
13, the design of purified water, installation, ozone disinfection basis, welding, verification confirmation and other parts of the non-compliance
14, the purified water drawings do not match the actual, the various control valves should be indicated in the drawings;
15, piping, storage tanks, welding problems
16, reserve outlet, back to the water outlet should have a thermometer, in order to control its temperature changes, there should be flow monitoring meter
