115t/hOverview of Double stage Reverse Osmosis Pure Water Equipment:

Secondary reverse osmosis equipmentThe system adopts different processes based on the quality of the source water. After being treated by a first level reverse osmosis equipment system, the conductivity of the produced water is generally less than 10 μ S/cm. After being treated by a second level reverse osmosis equipment system, the conductivity of the produced water is less than 2 μ S/cm or even lower. The reverse osmosis equipment system is supplemented withIon exchange equipmentperhapsEDI equipmentUltra pure water can be prepared.

II15t/hProcess flow of two-stage reverse osmosis pure water equipment:
Raw water tank - Raw water pump - Multi medium filter - Activated carbon filter - Softener - Precision filter - Primary reverse osmosis - Intermediate water tank - PH regulation - Secondary reverse osmosis - Purified water tank - Pure water pump - UV sterilizer - Micro porous filter - Water point

III15t/hTechnical characteristics of two-stage reverse osmosis pure water equipment:

1. The system adopts fully automatic control (manual control can also be used), and automatic backwashing and regeneration programs can be set during system operation;

2. The first and second stage reverse osmosis systems are equipped with reflux pipelines. The water produced by the first stage reverse osmosis system flows back to the original water tank, while the water produced by the second stage reverse osmosis system flows back to the first stage reverse osmosis water tank;3. The reverse osmosis equipment is equipped with chemical cleaning and disinfection devices;

4. A pH adjustment device is installed between the first and second level reverse osmosis to ensure that the conductivity of the produced water meets the requirements of the pharmacopoeia;

5. The secondary reverse osmosis membrane adopts a positively charged anti pollution reverse osmosis membrane to ensure the long-term stable operation of the reverse osmosis equipment;

6. The first stage reverse osmosis pipeline is made of 304 stainless steel material, and the second stage reverse osmosis is made of 316L stainless steel material;

7. At the first level of reverse osmosis andSecondary reverse osmosis equipmentBoth are equipped with online conductivity detection instruments, and the conductivity of the produced water can be viewed at any time;

8. There is a low-voltage protection switch before the first level reverse osmosis, and low-voltage and high-voltage protection switches before the second level reverse osmosis;

9. The first and second level reverse osmosis water recovery rates can be adjusted, with a first level reverse osmosis recovery rate of 50% -70% and a second level reverse osmosis recovery rate of 80%;

10. The purified water storage tank is equipped with a breathing filter, and the conveying pipeline is fitted withUltravioletAnd microporous filters ensure that pure water meets hygiene requirements.

415t/hPrecautions before operation of two-stage reverse osmosis pure water equipment

Before the trial operation of reverse osmosis equipment, it is necessary to first confirm whether the pre-treatment equipment is operating normally. When the important water quality analysis indicators in the raw water exceed the appropriate benchmark, the status of the raw water should be confirmed through a comprehensive water quality analysis. The specific contents that need to be confirmed before the system runs are as follows:

1. Raw water quality: SDI、 Turbidity, temperature pH、TDS、 Basic analysis items such as residual chlorine.

2. Can the supply of raw water meet the operation of the reverse osmosis system during system operation.

3. Whether the operating status of each preprocessing device in the system can meet the operational requirements of the reverse osmosis equipment.

4. Operation status and drug injection volume control of each drug injection device.

5. Calibration and installation status of each measuring instrument - whether it has been calibrated and installed correctly.

6. Setting and status of abnormal high and low pressure protection safety devices (i.e. pressure controllers).

7. The connection parts of piping and the fixed state of reverse osmosis pressure vessels.
