With the progress of society, people's awareness of food safety continues to increase, and China's current food safety legal system is also constantly improving to adapt to the development of the current food safety situation. Industry standards have also begun to be used in food hygiene supervision to regulate food production, stipulating that purified water, usually pure water, is required for both process water and finished water in the food and beverage industry. So, in today's beverage industry, water treatment equipment is the main equipment in production workshops. Purified water has become the basic raw material for the beverage industry, and the quality of water can affect the quality of products. The quality of products can affect the reputation of manufacturers, and the reputation of manufacturers is the foundation of survival. Therefore, the application of water treatment equipment in the beverage industry is becoming increasingly important. Reverse osmosis is currently one of the energy-saving and efficient methods for preparing water.

The process flow of reverse osmosis:

Characteristics of reverse osmosis system:

• The main components are all joint venture products with stable performance.
• The system has no vulnerable components, low maintenance rate, and long operating time.
• The polyamide composite membrane has a high desalination rate, which makes the system operate efficiently.
• The reverse osmosis equipment is equipped with a program start stop device, which can perform low-pressure flushing during startup and automatic flushing with a delay during shutdown.
• Pre processing protection system, which protects the high-pressure pump and RO membrane from damage caused by particles or other hard objects; At the same time, the low-pressure switch protects the high-pressure pump from damage due to low pressure. If the water supply is interrupted or under voltage, the system will automatically shut down.
• Both product water and concentrated water are equipped with flow meters to observe and adjust the operating water output and system water utilization rate. Through reasonable process design, the water utilization rate is high.
• There are corresponding interfaces and valves on the water supply, concentrated water, and product water main pipes of each section of the reverse osmosis device, which are connected to the cleaning system during cleaning.
• Real time detection of water quality using conductivity meters for raw water and RO produced water.
• RO concentrated water drainage is equipped with regulating valves to control the recovery rate of system water.
• The reverse osmosis membrane module is installed on a combination frame, which is equipped with corresponding pipelines and joints, including required brackets, fasteners, fixtures, and other accessories.
• The design of the reverse osmosis composite frame can meet the seismic intensity requirements of its factory site and the expansion requirements of its components.

Technical parameters of reverse osmosis system:
Design water temperature: 5-45 ℃
Primary water production: ≥ 20 m³/h
Primary recovery rate: ≥ 70%
Primary water production: ≥ 15m³/h
Secondary recovery rate: ≥ 75%
For every 1 ℃ increase or decrease in the operating temperature of the equipment, the water production increases or decreases by 3%.
