Protection and maintenance strategies for irrigation systems under complex water quality conditions

Progress in Physical Filtering Technology
The intelligence level of automatic backwash filters continues to improve, and the backwash frequency can be automatically adjusted according to pressure difference and water turbidity. The new laminated filter has a 30% increase in flux and is easier to clean and maintain. Centrifugal sand separators have significant advantages in treating high sediment content water sources. 

Chemical treatment plan
The treatment technology for high salinity water quality continues to improve, including the cost reduction of pre installed reverse osmosis systems and electrodialysis technology. The automatic injection system for acidic substances can accurately control the pH value and prevent the precipitation of calcium carbonate. The new slow-release chlorine tablets and fungicide dispensing system are safer and more precise. 

System design optimization
The system design standards for different water quality characteristics are gradually maturing. For water with high iron and manganese content, a specialized gas water mixed oxidation device is required, and for water with high organic matter content, a multi-stage filtration scheme is needed. The online water quality monitoring and automatic regulation system has become a standard configuration for high-end projects.
