DEIONIZATION SYSTEMS

DEIONIZER MODELS

MSB SERIES - Separate-bed ion exchange system designed for industrial high-purity water applications. Individual tank capacity ranges from 100,000 grain to 3,440,000 grain with continuous flow rates of 5-600 GPM. Tank diameters from 16" to 96" and service pipe connections from 1" NPT to 6" flange are available. Single and twin alternating systems are available with a wide variety of hardware and instrumentation packages. Standard design assume use of 30% hydrochloric acid and 50% sodium hydroxide chemical for resin regeneration. Contact Marlo, Inc. for information on larger tank sizes and custom sized applications.

Features/Benefits

  • Heavy-gauge carbon steel pressure vessels internally lined with a chemically resistant vinylester coating. All exterior surfaces are coated with a acid and caustic resistant "Safety Blue" paint finish. Non-ASME construction with 100 psig working pressure.
  • Flat-false bottom resin support with a hub-radial, non-clogging underdrain constructed of PVC for the ultimate in corrosion resistance.
  • High capacity, strong-acid cation exchange resin in hydrogen-form.
  • High capacity, Type 2 strong-base anion exchange resin in hydroxide-from (shipped in chloride form).
  • Sch 80 PVC face-piping assemblies with thermo-plastic, normally-open, "Y" pattern diaphragm control valves. Vessels with service piping 4" and larger utilize Sch 80 PVC face-piping and double-acting butterfly control valves. All control valves are air-operated requiring a 80-100 psig of clean, plant air supply.
  • Cation and anion vessels are mounted on a structural carbon steel skid and pre-piped to the fullest extent for minimal floor space requirements and ease of installation.
  • Comprehensive Programmable Logic Controller (PLC) system pre-wired in a NEMA-4X electrical enclosure. Includes all operator switches, push-buttons, indicator/alarm lights, and heavy-duty solenoids for control valve actuation.
  • Panel-mounted system flow meter and DI water conductivity monitor with digital display.
  • Pre-assembled system pressure gauge and sampling valve center.

Optional Equipment

MMB SERIES - Mixed-bed ion exchange system designed for industrial ultra-pure water applications requiring only trace amount of dissolved solids. Individual tank capacity ranges from 43,000 grain to 403,000 grain with continuous flow rates of 10-150 GPM. Tank diameters from 16" to 48" and service pipe connections from 1" NPT to 3" NPT are available. Single and primary/polisher twin systems are available with a wide variety of hardware and instrumentation packages. Standard design assume use of 30% hydrochloric acid and 50% sodium hydroxide chemical for resin regeneration. Separate sources of softened water and compressed air are required for the regeneration process. Contact Marlo, Inc. for information on larger tank sizes and custom sized applications.
