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 self-cleaning strainers, and offers the following features. See Everfilt’s low head cleaning screen filters for dewatering and solid recovery for slurries and high solids wastewater. Everfilt’s line of automated backwash controllers allows the filter system operator the advantages of fully automated filter system backwashing.

Single Unit Constructed Cartridge

Filtration Range - The SMS self-cleaning screen filter has cartridges that 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 on the self cleaning strainer 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. This uniformity affords a complete water filtration; 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 for the SMS series self-cleaning filter.

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

Self Cleaning Screen Filters - 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 water 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 backwash port. Closing the valve puts the screen filter back into the filtration mode. Manual or automatic valves are available for self cleaning strainers. For best water filtration results, maximum recommended flow through backwash valve is 300 GPM.
