Sefar is one of the world’s leading manufacturers of precision woven filtration fabrics and high performance replacement filters, including filter belts, filter disk covers and other filtration assemblies.
We've set new international standards as a problem solver in many demanding applications including potable water treatment, industrial water treatment and commercial/residential water purification.
Potable Water Treatment
Sefar is a leading supplier of micro-screens for the prefiltration of potable water. Micro-screens can be easily regenerated and allow substantial reduction of the bio-burden of the second stage sand filters or membranes.
Sefar micro-screens are designed to support demanding waterworks applications.
Industrial Water Treatment
Sefar is a leading supplier of screens and micro-screens for prefiltration micro-screening of industrial water. Sefar micro-screens can be easily regenerated and allow substantial reduction of the burden on second stage filters or membranes.
Sefar’s aim is to substantially reduce the filtration effort for industrial water by the use of micro-screening.
Residential water purification systems incorporate carbon granules and molecular sieves to remove a wide variety of chemicals. OEMs of these filters use Sefar screens to retain the granules in the filtration cartridge and prevent them from entering the drinking water. The precise mesh openings and high throughput capacity of Sefar screens make them the ideal choice for this application.
Sefar screens are made from polymers such as polyamide, polyester and polypropylene and have been tested extensively by independent agencies to ensure that the material for your water filter is very safe and of consistent high quality.
Rotary Disc Filter
Rotary disc filters are best suited for continuous solid / liquid separation of bulk materials when little or no cake washing is required. Utilizing the experience gained from being a leading supplier for many years, Sefar has designed segments or covers for rotary disc filters for different applications in environmental industries.
All Sefar micro-screens for disc filters are engineered to give maximum performance in throughput, cleanability and mechanical resistance.
Based on equipment design, very open micro-screens with maximum throughput, shrinkable micro-screens for optimized fit and screens for high loads have been engineered.
Fabrication for Rotary Disc Filters
By adding various available standard features to the desired filter cover the filter cover can be customized according individual needs without risk and with little extra costs.
- Edge reinforcement against premature edge wear
- Zipper to make easy fixing possible
- Multifilament or rubber gasket sealing at the bottom
Rotary Drum Filter
Rotary drum filters are best suited for continuous solid / liquid separation of bulk materials under vacuum or hyperbaric conditions. Utilizing the experience gained from being a leading supplier for many years, Sefar has a full range of rotary drum filter belts and covers for applications in environmental industries.
Sefar micro-screens for drum filters are engineered to suit specific requirements such as porosity, abrasion resistance and cleanability based on filter drum construction. Sefar is often involved at the design stage of the equipment. Sefar application engineers are happy to help you choose the appropriate micro-screen solution for your filter equipment.
Fabrication for Rotary Drum Filters
Adding desired features to a standard Sefar rotary drum filter design can increase the value of the equipment tremendously and avoid costly re-engineering work.
- Laser-cut pieces
- Specially treated edges for reinforcement
- Sealed stitching for extra tightness
- Closures with Velcro
