Site footage and equipment photographs supplied for a canteen project in Dali, with a summary of a 39-item commissioned test report. Its conclusion applies to the submitted sample and tested items described in that report.
Visible equipment and project scope
The footage and photographs show a membrane treatment skid, filtration components, a pump, controls and a cylindrical device labelled as ultraviolet disinfection equipment. These identify visible components, rather than establish a particular membrane model, rated output or validated disinfection performance. The project name and location follow the owner’s description.

How to read these records
This page summarizes four photographs of a submitted-sample report, rather than a new test or an independent authenticity verification. The sampling fields are not completed on the photographed first page; its notes attribute the stated collection location to the commissioning party. The conclusion cannot be extended to untested items, every tap, current operation or continuous water quality. A momentary conductivity display is not interchangeable with laboratory dissolved-solids or microbiological results. Consult the original report and issuing institution when checking applicability.

Canteen handover and maintenance questions
Confirm intended uses, peak service periods, storage turnover, sampling points, cleaning responsibilities and a monitoring plan. Equipment supply, installation, commissioning, sampling, testing and maintenance are distinct responsibilities and should follow the actual agreement.
