In-Line Fine Screens For Irrigation, Ballast Water, Water Re-Use

Description and Working Principle

This unit is an automatic self-cleaning filter offering a very efficient method of filtering water containing large quantities.

Dirty water enters the filter and is pre-filtered through a coarse screen, the first stage of filtration. This prevents passage of large particles which may damage the filter internals. The water then flows through a sintered multi layer stainless steel fine screen and flows out through the outlet port. The dirt particles gradually build up a filter “cake” on the inside of the fine screen. This “cake” improves filtration efficiency as it performs a finer filtration and creates a pressure differential across the screen. The differential pressure rises until the predetermined value is reached (normally 0.5 bar).

The differential pressure is monitored by the control system, and a flushing cycle is activated once the predetermined differential is achieved.


Performance and Technical Features 

• High screening efficiency due to its unique stainless steel sintered filtering element
• Low head-loss 
• Most efficient and fully automatic self-cleaning mechanism
• Filtered water supply is not interrupted during flushing 
• Filter uses small quantities of water to flush the screen 
• Simple and easy to operate 
• Long service life thanks to anti corrosion protection coating and stainless steel sintered screens
• Low maintenance cost 
• Low cost per cubic meter of filtered water
