3M™ Zeta Plus™ HT Series Filter Cartridge is our charge-modified depth filter made from inorganic filter aids, refined cellulose and cationic resin. Its composition and structure yield a high-tensile strength media, which performs efficiently under elevated operating temperatures or repeated hot water sanitisation cycles.
3M™ Zeta Plus™ HT Series Filter Cartridge combines depth filtration and electro-kinetic adsorption, providing efficient haze and particle removal at micron ratings lower than the mechanical rating alone. It’s produced from inorganic filter aids, refined cellulose and cationic resin in several grades to meet the different filtration needs required by your applications. Our cartridge is constructed from individual cells. Each cell is made using polypropylene moulded edge seals and internal separators for high performance. They’re made into a single unit by three 316 stainless steel bands in the core of the cartridge with polypropylene cell separators. We also make various gasket materials, depending upon application, to provide compatibility with a range of chemicals. The filter cartridges are available in 8, 12 and 16 inch diameters. The Zeta Plus cartridge system offers a number of advantages over conventional plate and frame filters. Since the cartridge system utilises a totally enclosed housing, there is no product leakage and no exposure of the filter media to external contamination, allowing for effective use of the media, higher throughputs, and low operating costs. In competing plate and frame filter press designs, the filter material is open to the environment making both filter media and product susceptible to external contamination. Their ‘open’ design requires more frequent media change-out cycles, typically every few days. The results are lower throughputs and higher material, labour and operating costs. Plate and frame filters are labour intensive, requiring two people four to eight hours to change out the media. Zeta Plus cartridges are easy to install and remove, usually taking only 15 minutes, giving you significantly less labour cost and allowing you to focus on the work, not the equipment. The savings become substantial when considering the floor space reduction of the vertical Zeta Plus housing design and a typical 50% or greater decrease in initial capital cost when compared to a comparable plate and frame filter. Quality Control We follow strict adherence to an ISO quality certified assurance scheme when manufacturing our Zeta Plus HT cartridges. We label all cartridges with identification numbers to provide complete traceability and each cartridge is also engraved with its lot number and grade to assure complete traceability. The extended filter life enables high throughputs, less cartridge change-outs and reduced operating costs. All components are EC 1935/2004 and FDA CFR Title 21 compliant and safe for food and beverage filter applications.
