SELF CLEANING SCREEN FILTERS - SMS SERIES

• AUTOMATIC BACKFLUSH (REVERSE FLOW)
• MANUAL BACKFLUSH (REVERSE FLOW)
• MANUAL CLEAN

Everfilt has incorporated the unique configuration and high strength of profile wire in the SMS Series of screen filters, and offers the following features.

Single Unit Constructed Cartridge

Filtration Range - Cartridges are available with 35, 50, 75, 100, 150, and 200 mesh equivalent slot openings.

High Strength Cartridge - Collapse strength 125 PSI and Burst strength of 400 PSI. This feature alone eliminates common screen blowouts, collapse, rupture or tearing of woven or perforated screen material, and gives maximum protection to the system.

Operation Uniformity - Filtration and reverse flow backwashing are accomplished over entire surface. There are no blind spots or partial cleanings.

Mesh Uniformity - The slot openings are fixed and welded, unlike woven materials that can flex and move.

Housing - Stainless Steel - easy access closure, cartridge aligner, ribbed for collapse strength and adapted for groove type coupling. High pressure stainless or epoxy coated carbon steel housing is optional.

Cleaning - Available in manual clean (normally for single cartridge systems), or in reverse flow backwash with either automatic or manual valves.

SCREEN FILTER OPERATION

Single Unit - Raw water enters the screen area and the particulate material is deposited on the screen. When sufficient particulate material is deposited on the screen, it is removed through the access port and manually cleaned by flushing, wire brushing, air blasting, soaking or steam cleaning.

Multi Unit - During filtration raw water enters the screen area through the backwash valve, and the particulate material is deposited on the screen. Backwashing is accomplished by opening the backwash valve, which shuts off the incoming water, and at the same time, opens the backwash port to a near atmospheric condition. Filtered water from the adjacent units is forced backwards through the screen, cleaning it and forcing the particulate material out of the backawash port. Closing the valve puts the screen filter back into the filtration mode. Manual or automatic valves are available. Maximum recommended flow through backwash valve is 300 GPM.
