Procurement companies must confirm the following for the installation of pure water equipment:

1. Confirm Installation Dead Corners

Measure the dead corners during actual installation and confirm the environmental protection project installation meets design standards.

②Detail the test results in the report.

2. Verify that the welding of components/systems/equipment is conducted according to the approved welding procedures; confirm that the system/equipment's automatic and manual welding inspection rates meet the regulations.

3. Pressure Test Confirmation - Verify system leakage during system pressure testing; the pressure test program meets requirements and was successfully completed.

Safety Precautions for Environmental Protection Equipment Installation

1. During the installation of environmental protection equipment, purification equipment and fans should be assembled according to standards and in order. Care should be taken to prevent debris from falling into the fan during installation to avoid damaging the blades.

2. Installation Notice: As glass fiber reinforced plastic is generally flammable, no open flame is allowed during installation and maintenance.

3. Environmental Protection Equipment Installation: To ensure purification effectiveness, the installation cost for environmental protection projects should maintain a circulating liquid concentration in the storage tank. When the waste gas is acidic, the concentration of sodium hydroxide (NaOH) should generally be kept between 2% to 6%. When washing alkali mist: the alkali concentration of the circulating liquid should not exceed 15%.

Purchasing companies must confirm the following for the installation of pure water equipment:

1. Confirm the installation of components listed as critical (films, carbon, etc.) matches the on-site conditions.

2. Material confirmation for parts will be detailed in the parts list with the date and signature marked, for environmental engineering installation projects, and attached as an appendix to the verification report.

3. Instrument Calibration Report Verification

Verify if the system/equipment instruments have all been calibrated and are within the validity period.

Confirm that all instruments used for IQ tests have been calibrated and are within the validity period.

All calibrations must trace back to the national metrological standard.
