Contributing to manufacturing of advanced pure water used in manufacturing processes

The pure water production system RO series for industrial use packages all the equipment required for pure water supply into a single unit, eliminating the need to select detailed specifications.
Our product lineup can be selected according to the water production volume. And, two models are available according to the application and the water quality required. In addition, other options are available.

Features

  • Two models to choose from according to the water quality and application

    Two models are available: the HP model, which uses purified-grade water, and the simple DM model.
    You can choose according to your desired water quality.

  • Necessary equipment packaged in one system

    All equipment required for pure water production is packaged into a unit. Reduces the time required to select equipment.

  • Unit design reduces costs and ensures short delivery times for peace of mind

    Thanks to its base design, the purchase and manufacturing costs are reduced to realize a low price.
    In addition, this is a general-purpose product designed according to the water production volume, resulting in shorter delivery times.

  • Trusted at medical sites, powered by technology developed for energy-saving water sprinkling systems

    Our dialysis water purifying apparatuses, which are the basis of the development of the HP model, have been installed at medical sites in Japan at more than 1,000 locations. Widely used and trusted throughout the medical industry.
    The DM model was developed based on the E mizu Shower System patented as a compact water sprinkling system for outdoor units.

  • Options available upon request

    Optional functions corresponding to required water quality grades are available.

Model introduction

  • For sites requiring pyrogen removal

    HP models

    Highly Purified Water Model

    Pretreatment + Water softener + RO membrane
    + UF membrane

    We have released water purifying apparatuses for artificial dialysis for industrial use. The UF membrane module installed at the latter stage of the RO membrane module removes pyrogens and endotoxins to supply safe water (LRV5 or higher). Recommended for producing water for medical raw material production and laboratory water.
    The water quality conforms to the Standards for Purified Water of the Japanese Pharmacopoeia; the RO series can be designed to achieve conductivity of 2.1 μS/cm or less and 95% reduction of endotoxins.*

    • *Depending on our proposal including options

    Applications

    • For producing water for production of medical materials and cosmetics

    • For producing laboratory water and water for prototyping

  • For sites where scale and minerals need to be removed

    DM models

    Demineralized Water Model

    Pretreatment + RO membrane

    Reliably removes impurities ionized by the RO membranes. Removes hardness components from raw water with a minimal system configuration. Ideal not only for working with manufacturing equipment like a boiler and sprayers, where scale buildup is likely during water supply, but also for removing minerals to make it easier for additives to dissolve in extraction solutions and solvents.
    The simple structure reduces introduction costs. No chemicals are needed, and running costs are low.

    Applications

    • For producing water for food production and extraction water

    • For producing cooling water

    Optional Specifications

    • Reuse of concentrated wastewater by adding UF membranes

      The UF membrane module purifies the water concentrated by the RO membrane module to return it to the feed water tank. About 30% of tap water is saved.

    • Adding UF membranes to pretreatment

      Adding a UF membrane module before the water softener extends the expected service life of the RO membrane module.

    • Adding a hot water disinfection function

      The system has heat resistance, which allows for hot water disinfection within the dotted line area.

    • Adding an EDI/Ion exchange tower

      Adding an EDI or Ion exchange tower after the RO water tank further enhances the water quality.

    Optional function

    • Raw water tank

      The DM-400/600/800 does not include a raw water tank. If necessary, we can install it as an optional service. The DM-1000/2000 includes it as standard.
