Microguard Series Cartridges

Summary

Product identification

The MicroGuard™ Series comprises membrane filter cartridges designed for reliable bacteria and protozoan cyst reduction in drinking water without adding chemicals. They are suitable for Point-of-Use (POU) applications.

• MG-10MCB
  • Carbon-Block/Membrane cartridge
  • 10-inch nominal length microfilter (0.15 micron absolute rating)
  • Uniquely designed with integral carbon block and sediment pre-filtration for chlorine taste and odor reduction and extended life.
  • Features 2.5 times greater filtration surface area than some anti-microbial carbon blocks.
• MG-10T
  • Triple Element cartridge (membrane only)
  • 10-inch nominal length microfilter (0.15 micron absolute rating)
  • Uniquely constructed with three membrane elements integrally sealed for higher flow rates and longer life.
  • Life can be extended using PENTEK carbon block or sediment pre-filtration options.
• Common Features
  • Absolute 0.15 micron particle retention for bacteria and protozoan cyst reduction.
  • Utilizes patented highly asymmetric polyethersulfone membrane with proprietary hydrophilic formulation.
  • Double O-ring end cap seals for absolute sealing in PENTEK Seal-Safe™ 3G housings.
  • Effectiveness is not susceptible to common substances like hydrogen sulfide (H₂S), natural organic matter (NOM), and total dissolved solids (TDS).
  • Not certified for sale in California, Iowa, Massachusetts, and Wisconsin.
  • Not intended for converting wastewater or raw sewage into drinking water.
  • Not intended for reducing pathogenic (disease-causing) virus particles.
  • Intended for use on visually clear drinking water that meets all other public health standards.

Operating limits

• Water Temperature Range: 40-140°F (4.4-60°C)
• Pressure Differential: 88 psi (6.1 bar), max.
• Storage Temperature Range: 35-104°F (6.0-40°C)
• pH Range: 2-12
• Operating Pressure Range: 5-88 psi (0.35-6.1 bar), max.
• Water Turbidity: < 1 NTU

Feed water

The cartridges retain the natural mineral content of water and their protection is not susceptible to common substances in water like H₂S, NOM, and TDS.

WARNINGS:

• Do not use on water that may be contaminated by untreated surface water, water that may be contaminated by human or animal sewage, or other wastewater.
• These cartridges are not intended for reducing pathogenic (disease-causing) virus particles, if present in the water, to below safe levels.
• These cartridges are intended for use on visually clear drinking water that meets all other public health standards.

Product water

• Bacteria Reduction: > 99.9999% (> 6-Log), challenged with > 50,000,000 organisms per 100 mL. Organism: Brevundimonas diminuta (0.2 micron in size).
• Cyst Reduction: > 99.9999% (> 6-Log), challenged with > 1,000,000 microspheres per mL. Surrogate cyst procedure using 3.0 micron latex microspheres.
• Removes bacteria, cysts and other particles down to 0.15 micron in size.

Electrical

• No electrical power required (except for accessory pump, if needed for pressure).
• Protects even during power outages or intermittent power.

Mechanical / hydraulic

• Materials of Construction:
  • Membrane: Polyethersulfone
  • Membrane Assembly: Polystyrene, epoxy resin
  • Carbon Pre-Filter (MG-10MCB only): Activated carbon with synthetic polymeric fibers and binders (Fibredyne™ technology)
  • O-ring Seals: EPDM
  • End Caps: Top: Polystyrene, Bottom: Polypropylene
  • Netting: Bottom: Polyolefin (MG-10MCB only)
• Dimensions:
  • MG-10MCB:
    • Maximum diameter: 2.875" (73 mm)
    • Maximum Length: 10.283" (261.18 mm)

    • Maximum Length: 10.294" (261.47 mm)
• Both models fit in PENTEK 3G housings, SlimLine®, and Standard housings.
• Requires only normal water line pressure to operate.
• No waste water or brine/concentrate flushing.
• Recommended Flow Rate:
  • MG-10MCB: 1 gpm
  • MG-10T: 3 gpm (The MG-10T is ideal for applications up to five gallons-per-minute)
• Initial ΔP @ Flow Rate:
  • MG-10MCB: 11 psid @ 1 gpm (0.76 bar @ 3.8 lpm)
  • MG-10T: 13 psid @ 3 gpm (0.9 bar @ 11.4 lpm)
• Estimated Capacities:
  • MG-10MCB: 200-600 gallons (750-2,300 L)
  • MG-10T: 600-1,800 gallons (2,300-6,800 L)
  • Note: Capacities may vary depending on local water quality, type of pre-filtration, and acceptable minimum flow rate.
