Industrial Ion Exchange Systems

Marlo designs and manufactures both standard and specially engineered ion exchange equipment for an array of applications including deionization (separate and mixed bed), dealkalizers, and condensate polishers.

Separate Bed Deionizers - MSB Series

The Marlo 'MSB' Series Automatic Separate-Bed Deionizer (DI) systems are engineered to economically produce high purity water through the removal of total dissolved solids (TDS).

Automatic DI System - MSB-F Series

The Marlo 'MSB-F' Series Automatic Separate-Bed Deionizer (DI) system offers a corrosion resistant alternative for the economical production of high purity water in industrial applications...

Mixed-Bed Deionizer - MMB Series

The Marlo 'MMB' Series Mixed-Bed Deionizer (MBDI) systems are designed for industrial, ultra-pure water applications where only trace amount of dissolved solids are allowed.

Condensate Polisher System - MCP Series

The Marlo 'MCP' Series condensate polisher system offers a sound solution for removing impurities such as iron, copper, and hardness from returned steam condensate resulting in improved boiler feedwater quality and lower operating costs.

Boiler-Feed Applications - MDAS Series

The Marlo 'MDAS' Series is designed for larger industrial boiler-feed applications. Individual tank capacity ranges from 50,000 grain to 980,000 grain with continuous flow rates of 10-300 GPM.

Dealkalized Water Systems - MATD Series

The Marlo 'MATD' Series is designed for commercial and industrial boiler-feed applications demanding a continuous dealkalized water supply.

Electro-Deionization Skids - EDI Series

The Electro-Deionization process is the latest technology to achieve ultrapure water. EDI uses ion exchange resins in the presence of a DC voltage potential to remove cation and anion contaminants from the feed water supply.

Portable Exchange Deionization Tanks (PEDI)


Jumbo-Type, Portable Exchange Deionziation Tanks (PEDI) are used for larger, high purity water treatment applications where the convenience for using an off-site resin regeneration service is desired.

Packaged Batch Resin Regeneration Plants (PEDI)

Marlo Packaged Batch DI Regeneration Plants support the providers of a portable exchange deionization (PEDI) service business with an operator friendly, pre-engineered design to regenerate exhausted mixed-bed resin at their facility.
