It is produced from a unique mineral deposit having high surface area and porosity. The surface structure of Micro-Z features microscopic mineral projections that allow particulate matter to penetrate deeply into the bed. These properties make Micro Z an ideal filtration media.Micro Z™ Media Features Benefits• Higher Solids Loading Capabilities = Reduces back washing frequency and saves water• Enhanced Filtration Performance = Finer filtration provides higher quality of water and reduces the load on downstream equipment• High Service Flow Rate = Reduces new equipment costs and provides expansion opportunities for existing equipment• Light Weight = Reduces shipping cost and easier to handle• Lower Pressure Loss = Allows for higher flow ratesPhysical Properties of Micro Z• Color: Light Green• Bulk Density: 55 lb/CuFt• Specific Gravity: 2.2 gm/c• Mesh Size: 14 x 40• Uniform Coefficient: 1.9• Harness: 4 (Mohs Scale)Conditions for Operation of Micro Z• Bed Depth: 36-48 Inches• Freeboard: 50% of bed depth• Service Flow Rate: 12 to 20 gpm• Backwash Bed Expansion: 30% to 40%NOTE: Allow Bed to Soak Overnight Before First BackwashWhy Use Micro Z vs Conventional Media?Micro Z - Nominal rating is 5 Micron with Load Capacity of 2.8 XCompared To:Sand - Normal rating is 20 Micron with Load Capacity of 1.0 XSand & Anthracite - Normal rating is 15 Micron with Load Capacity of 1.4 XMultimedia - Normal rating is 12 Micron with Load Capacity of 1.6 XMicro Z™ Loading Information
