With the improvement of quality of life and hygiene requirements, people's demands for water quality in the food industry are becoming increasingly strict, especially in terms of taste and hygiene indicators. Food processing water equipment can pass tap water through a reasonable pretreatment system to remove particles, impurities, colloids, and residual chlorine in the water. Then, reverse osmosis technology is used to remove bacteria, viruses, and most harmful heavy metal plasma from the water. It can be directly used for food production water. The system is set to manual and automatic operation, and can achieve automatic control of raw water pumps, high-pressure pumps, and pure water pumps. Automatic start stop, automatic flushing, waterless shutdown, high and low pressure protection, thermal protection, liquid level control and other protective functions.

1. Using a first stage reverse osmosis process to prepare water for food and beverage production, the process is as follows:

2. Using a two-stage reverse osmosis process to prepare purified water, the process is as follows:

Raw water tank → booster pump → multi-media filter → activated carbon filter → security filter → high-pressure pump → first stage reverse osmosis → high-pressure pump → second stage reverse osmosis → pure water tank → ozone sterilization → finished water tank → pure water pump → microporous filter → filling

3. Using ultrafiltration technology to prepare mineral water, the process is as follows:

Raw water tank → booster pump → multi-media filter → activated carbon filter → booster pump → ultrafiltration → intermediate water tank → ozone sterilization → finished water tank → booster pump → microporous filter → filling

1. The ultra-low pressure roll type composite reverse osmosis membrane has good desalination effect, low operating pressure, excellent water quality, low operating cost, and long service life.

3. Flow meters are installed for both produced water and concentrated water to monitor the operating water output and system recovery rate.

4. There are pressure gauges before and after the security filter, pressure gauges before and after reverse osmosis, and continuous monitoring of the pressure difference between reverse osmosis and fine filter membrane to indicate when the filter element needs to be replaced.
