The use of purified water is inseparable from the raw water report. Generally, pharmaceutical companies use municipal tap water as raw water. If the company does not sample the raw water and cannot provide a tap water quality report, you can contact the local tap water supply company and ask the tap water supply company to produce a water quality report.
The raw water quality report includes water quality type, water quality conductivity, temperature, pH value and water composition analysis. Among them, the composition analysis of water includes dissolved oxygen, permanganate index, chemical oxygen demand, biochemical oxygen demand, trace elements and many other indicators. Purified water equipment manufacturers can make reasonable water treatment process selections through the detection results and analysis of these indicators. For example, whether pretreatment needs to add mechanical filters, activated carbon filters, double softeners, etc. Since the reverse osmosis system after pretreatment has relatively high requirements on the influent water, in order to ensure the good performance of the reverse osmosis membrane, prolong the service cycle of the system, and reduce the operating cost of the system, the raw water needs to be pretreated to make the water quality meet the influent requirements of the reverse osmosis system. .
Drinking water is the raw water of purified water, but the quality of raw water changes with the changes of seasons and geology. This should be fully taken into account when designing the system. If necessary, enterprises need to analyze the quality of raw water every quarter to avoid affecting Product water quality and continuous stability.
