1、 Design Basis

1. Raw water quality analysis report.

2. Requirements for water quality, such as electrical resistivity, microbial content, and other indicators.

3. Equipment operating environment requirements.

2、 Process flow design

1. Preprocessing system

-Multi media filter: removes suspended solids, sediment, rust and other impurities from raw water. Using quartz sand and other filter materials, regularly backwash to restore filtration performance.

-Activated carbon filter: adsorbs organic matter, residual chlorine, etc. in raw water to improve the taste and odor of the water. Choosing high-quality activated carbon also requires regular backwashing.

-Precision filter: further filters small particles to protect core components such as reverse osmosis membranes. Usually, 5 micron or finer filter cartridges are used.

2. Reverse osmosis system

-High pressure pump: provides sufficient pressure for the reverse osmosis process, promoting water to pass through the reverse osmosis membrane.

-Reverse osmosis membrane module: a core filtration component that can effectively remove dissolved solids, ions, microorganisms, etc. from water. Different specifications and brands of reverse osmosis membranes can be selected according to water production and quality requirements.

-Cleaning device: Regularly clean the reverse osmosis membrane to extend its service life.

3. Post processing system

-Ion exchange resin: further removes residual ions from water and increases the electrical resistivity of water. Different types of ion exchange resins can be selected as needed.

-UV sterilizer: uses ultraviolet radiation to kill microorganisms in water, ensuring that the microbial indicators of water quality meet the requirements.

-Terminal filter: such as a 0.22 micron microporous filter, to prevent bacteria and particles from entering the pure water storage and use process.

3、 Equipment selection

1. Determine the specifications and parameters of each equipment based on the raw water volume, water quality fluctuations, and water production requirements.

2. Choose brand products with reliable quality and stable performance to ensure the long-term operation of the equipment.

3. Consider the degree of automation of the equipment to facilitate operation and maintenance.

4、 Control system design

1. Adopting a PLC control system to achieve automated operation of the equipment. Functions such as automatic start stop and fault alarm can be set.

2. Real time monitoring of water quality parameters such as resistivity, flow rate, pressure, etc., and automatic adjustment of equipment operation status based on monitoring results.

3. Equipped with remote monitoring function, it is convenient for users to understand the operation status of the equipment at any time.

5、 Installation and Debugging

1. Install the equipment by professional technicians to ensure that the installation quality meets the requirements.

2. Conduct equipment debugging and trial operation, adjust and optimize various parameters to ensure stable and compliant water quality.

6、 Maintenance and upkeep

1. Develop a detailed maintenance plan and regularly maintain and upkeep the equipment.

2. Regularly replace vulnerable components such as filter cartridges, reverse osmosis membranes, ion exchange resins, etc.

3. Regularly clean and disinfect the equipment to prevent the growth of microorganisms.

4. Establish equipment operation files to record the operation and maintenance of equipment, providing a basis for equipment management.

The above process plan can be adjusted and optimized according to the actual situation to meet the needs of different users for pure water equipment.
