Automatic Multi Media Filtration System Manufacturer
Product Introduction
The Automatic Multi Media Filtration System provides continuous and efficient pretreatment for industrial water treatment processes. Equipped with automatic backwashing functions, the system minimizes maintenance while ensuring consistent filtration performance. It is suitable for industrial facilities requiring reliable water quality and long-term stable operation.
The Automatic Multi Media Filtration System is designed to provide reliable and continuous removal of suspended solids, turbidity, and particulate contaminants from industrial and municipal water supplies. By utilizing multiple filtration media with different particle sizes and densities, the system achieves efficient depth filtration while maintaining low pressure loss and stable water flow.
With automatic backwashing and intelligent control, the system minimizes maintenance requirements and provides dependable long-term performance for a wide variety of industrial water treatment applications.
Operation Guide
System Start-up
Before operation, verify that the filtration media has been properly loaded and all valves are in the correct operating position. Start the feed water pump gradually until the designed operating flow rate is reached.
Normal Filtration
Raw water enters the top of the vessel and passes downward through multiple media layers. Suspended solids are retained within the filter bed while clean water exits through the outlet manifold.
Backwash Process
When differential pressure reaches the preset value or the programmed operating time has elapsed, the system automatically initiates the backwash cycle. Water flows upward through the media bed, removing accumulated contaminants and restoring filtration efficiency.
Return to Service
After backwashing is completed, the system automatically returns to filtration mode without requiring complicated operator intervention.
Maintenance Guide
Daily Inspection
Monitor inlet and outlet pressure, operating flow rate, and backwash frequency to ensure stable system performance.
Filter Media Inspection
Periodically inspect the filtration media for contamination, channeling, or media loss. Replace media when necessary according to operating conditions
Valve and Instrument Maintenance
Regularly inspect automatic valves, pressure gauges, control systems, and piping connections to ensure reliable operation.
Scheduled Maintenance
Follow the recommended maintenance schedule for pumps, actuators, PLC systems, and instrumentation to maximize equipment service life.
