Technical design guidelines

The design of this water treatment process is based on full consideration of the following factors:

2.1 users' requirements on the quality and yield of product water;

2.2 reliability of process design;

2.3 simplicity of equipment and intelligent operation;

2.4 investment and operating expenses;

2.5 physical and chemical cleaning of equipment;

2.6 stability of water quality;

2.7 reliable online monitoring means.

The system has requirements on the outside world

3.1 water supply: municipal water supply ≥50m3/h.

3.2 power supply: the user shall transmit the power cord to the electronic control cabinet of the equipment.

3.3 water production: the water produced by the supplier shall be connected to the nearest inlet of the ultra-pure water pipeline of the user.

3.4 site: the user shall provide the equipment area.

3.5 drugs: all drugs consumed during debugging and operation shall be provided by users.

The technological requirements

4.1 raw water quality: local municipal tap water standard (conductivity ≤200us/cm)

Effluent is 4.2: equipment processing level 1 reverse osmosis conductivity after 20 us/cm or less, secondary reverse osmosis conductivity 5 us/cm or less, terminal EDI water resistivity Ω 15 m * cm or more

4.3 system water output: the water output of the first-stage reverse osmosis pure water machine system is 30m3/h-35m3/h (old equipment: now there is a set of single stage 15 tons + double stage (first stage 14 tons + second stage 6 tons), the water output of the second-stage reverse osmosis pure water machine system is 20m3/h (newly added), and the designed water output of the terminal EDI (electric desalination) system is 18m3/h-20m3/h.

The design principle and process flow of this set of equipment are made according to the requirements of users, and the final interpretation right belongs to qin tai sheng water treatment
