The water of a particular program does not interfere with the specificity, accuracy and precision of the program. Process definitions alone are not sufficient to define the required water quality. Many parameters have qualifiers that ultimately meet the requirements of appropriateness and validation as determined by the end user. Because a variety of applications may have a great impact on the composition and quantity tolerance of pollutants. Therefore, it is not uncommon for water quality parameters to be supplemented by identifying intended applications, specific pollutant problems to ensure that desired results are achieved. In the Hospital Hemodialysis Room, the water filtration Ro system is needed;

Pump ---- Quartz sand filter ------ AC filter----- Soft resin filter----- Precision filter--- Prime high pressure pump--- Prime RO system----- Secondary high pressure pump------- Secondary RO system--- Pure water out

1. For the preparation of multi-bed hemodialysis and related treatment water in medical institutions;
2. The water involved includes: water for powder preparation concentrate, water for dialyzer preparation, water for dialyzer reuse;
