About SS MULTI CARTRIDGES FILTER
Stainless Steel (SS) Multi-Cartridge Filters are high-precision, heavy-duty industrial pressure vessels engineered to hold multiple filter cartridges simultaneously. While bag filters are preferred for high dirt loads and bulk pre-filtration, multi-cartridge filters are designed for fine polishing, removing ultra-fine suspended solids, sediment, and microscopic particulate contaminants down to sub-micron levels (as fine as 0.1 microns).
Key Specifications & Architecture
Multi-cartridge systems are highly customizable and scale based on your exact purification parameters:
- Material of Construction (MOC): Manufactured in SS 304 for standard industrial/commercial water lines and SS 316 / SS 316L with electro-polished or mirror-finish interiors for aggressive chemicals, pharmaceuticals, and sterile food/beverage applications.
- Capacity Design: Built to securely align anywhere from 3 to over 100+ cartridges within a single housing to comfortably match severe industrial flow rate volumes.
- Cartridge Compatibility: Accommodates standard lengths of 10, 20, 30, or 40 inches. They are compatible with various element styles including PP melt-blown (spun), pleated depth filters, string-wound, or sterile membrane cartridges.
- Adapter Connections: Configured to accept different cartridge ends, including Code 7 (226 O-ring with locking tabs), Code 3 (222 O-ring), or standard Double Open End (DOE) flat gaskets.
- Sealing & Closures: Built to handle operating pressures up to 10 Bar (or higher custom limits). Vessels utilize heavy-duty V-bands, swing-bolt lid assemblies, and PTFE, Viton, or EPDM O-rings to prevent bypass leaks.
Working Principle
- Inlet Distribution: The process liquid enters through the housing's inlet connection, where an internal distribution plate evenly spreads the fluid around the array of vertical cartridges.
- Outside-In Filtration: Liquid pressure forces the fluid to pass through the filter media from the outside toward the hollow core of each cartridge. Particulates are trapped along the depth or surface area of the media.
- Clean Discharge: Clarified liquid enters the center core of the cartridges, drops down into a sealed bottom collection plenum, and discharges safely via the bottom outlet.
- Monitoring: Differential pressure gauges monitor the pressure drop across the housing. When the pressure differential reaches the maximum limit (typically 1.52 Bar), the system is vented and drained to swap out the spent elements.
- A highly versatile, customizable vessel capable of accommodating anywhere from 4 to 28 internal cartridges based on your specific order.
- Manufactured from commercial-grade SS304 or SS316 with options for a mirror-polished or matte exterior finish.
- Rated for fine liquid filtration up to an operating pressure of 7 kg/cm (approx. 7 Bar) and temperatures up to 80C.
- Heavy-duty manufacturing vessel designed by Envifab Equipments for rigorous, continuous industrial processing applications.
- Engineered to fit standard industrial cartridge array counts with a strong emphasis on leak-proof internal guide plates.
- Ideally suited as an essential pre-treatment filter stage prior to reverse osmosis (RO) membranes, chemical polishing, or pharmaceutical process
