A complete water-analysis report is easier to review than a few screenshots of individual readings. Before choosing RO equipment, identify the water source, the sampling point and the production use. Keep each report with its original dates, units and notes.
Identify the water behind each report
Label each sample: a well outlet, mains-water connection, raw-water tank, water after pretreatment or permeate from an existing RO system. These sampling points describe different conditions and should not be treated as interchangeable.
If you alternate between wells or mix mains water with another source, explain how the sources are used. A report from one well does not establish the condition of every source supplying the factory.
Keep the full report and its units
Send all report pages, including the sample name, sampling or test date, laboratory, results, units, methods and notes. Reports in English or the local language can be supplied in their original form with a short explanation of the source and sampling point.
Record conductivity and TDS as shown; do not omit their units or substitute one result for the other. Retain wording such as “as CaCO3” for hardness or alkalinity where the laboratory uses it. For a handheld reading, state the displayed unit, measuring location and time, and identify it as an instrument reading rather than a laboratory report.
Show missing information clearly
Keep “not tested”, “not detected”, a blank result and a measured zero distinct. Include the detection limit if the report provides one. Do not fill gaps with estimates simply to complete a table.
If you have only partial analysis, send it and identify what is missing. Further testing should be discussed for your actual source, intended water use and proposed treatment arrangement. You can start an enquiry before every detail is available.
Separate source-water results from production-water requirements
The source-water report describes the incoming water. Your production specification describes the water needed at a particular use point. Send both separately and identify the use point. If equipment documentation or a customer specification states a water-quality requirement, keep its original wording and conditions.
For a high-purity or RO + EDI project, distinguish source water, RO permeate and the final production use point. Clarify where acceptance is assessed. See the single-pass RO, two-pass RO and RO + EDI comparison before discussing the treatment route.

Send the report with your factory requirements
Send report files to sales@qingzesystems.com and put a short project summary in the online enquiry. Share only project-relevant information; omit unrelated personal or confidential records.
