Seawater desalination equipment is a specialized device for desalination of seawater, and there are many methods for seawater desalination, and the process varies depending on the method used. Whether it is seawater desalination or desalination of brackish water, water pretreatment is the key to ensuring the long-term stable operation of the reverse osmosis system. The design of Liangqiao Environmental Protection's reverse osmosis seawater desalination control system adopts advanced computer program control at home and abroad, and the process and technical program are guaranteed to be of high quality. Liangqiao Group has been engaged in seawater desalination equipment for nearly 20 years. Today, we will take you to understand the process of reverse osmosis brackish water and brackish water desalination equipment:
1、Characteristics of seawater desalination technology
1) A comprehensive and efficient filtration system ensures the water quality requirements for reverse osmosis influent, and ultrafiltration is used for high turbidity seawater pretreatment;
2) Having experience in various energy recovery applications, an efficient energy recovery device can achieve an efficiency of up to 94%;
3) The selection of high-performance seawater corrosion resistant metal materials ensures a longer service life of the system;
4) Reasonable water intake and concentrated water discharge methods;
5) The operating cost of the economy;
6) The modular design concept makes the system location more reasonable, construction more convenient and fast, and meets different requirements
2、Design of seawater desalination process
Raw seawater - booster pump - high-efficiency filtration device - ultrafiltration device - high-pressure pump - reverse osmosis device - fresh water - energy recovery device - concentrated brine
3、Standard operating procedures for reverse osmosis seawater desalination equipment
1) Conduct a comprehensive water quality analysis test on the original seawater
2) Analyze and study the experimental results, develop the pilot process and scale;
3) Pilot scale, determining the design parameters of the pre-treatment process and system
4) Plan and budget;
5) Design and construction of the system;
6) Pilot testing before system debugging to determine debugging and operating parameters;
7) Debugging, trial operation, project handover, and training.
