The main function 1. Urban tap water is influent, and RO pure water (conductivity ≤ source water conductivity × 2%) and UP ultrapure water (resistivity ≤ 18.2 MΩ.cm) can be prepared at the same time; 2. The system automatically flushes the RO membrane; 3. UP ultra-pure water resistivity online monitoring; 4. RO pure water conductivity online monitoring. Main configuration 1. The model comes standard with a 0.1μm terminal microfilter; 2. Host size: (height x width x depth): 515 × 320 × 480mm (on-stage); 3. Weight: 35kg; 4. Working power supply: AC220V/50hz (power: on-stage 30-150w); 5. Water tank configuration: The on-stage model comes standard with a 15 liter pressure pure water tank. Technical Parameters Influent water source Total dissolved solids TDS<200ppm, water pressure 0.10-0.40Pa, water temperature 5-45°C Water production 5/10/20 l / h Effluent flow 1.5-1.8 L / min (when the tank is storing water) RO effluent water quality Conductivity ≤ Inlet conductivity x2% UP effluent water quality (online monitoring) Resistivity 17-18.2MΩ.cm Resistivity 18.2MΩ.cm (online monitoring) Microparticles ≤1/ml Microorganism ≤1cfu/ml Scope of application Preparation of solutions, reagents, buffers, etc. Student experiments / utensils washing small biochemical analyzers, physical and chemical testing, etc. Qualitative and quantitative analysis... Atomic absorption (AAs) / atomic emission (AES) ion chromatography (IC) plasma emission spectroscopy (ICP) High performance liquid chromatography (HPLC)... Remarks: (1. The water production capacity of this product refers to the rated water production capacity of RO membrane when the water temperature is 25 °C. When the water temperature is lowered by 1 °C, the water production of RO membrane drops by about 3%. When the water temperature is lower than 5 °C, the RO membrane will stop producing water. User selection must be based on factors that reduce the temperature of the winter water in the area; (2. In the area where the source water quality is poor (TDS>200ppm), the RO pure water quality may be reduced to the conductivity above 10μs/cm, and the water quality requirements are higher. The user recommends the UPR+UPHW combination scheme; |
