ユアサ 浸漬型膜 モジュール

Yuasa Immersion Type Modules is a tank-immersion-type module for a large-capacity membrane filtration using the precision filtration membrane (Yuasa membrane filter) that was originally developed by Yuasa Membrane Systems.
Yuasa Immersion Type Modules involves immersing a precision filtration membrane in water in the tank, to separate solids from raw water. This eliminates bacteria and fine particles and helps obtain treated water of consistent quality.


  • Space saving
    • ・No sedimentation basin or filtration machine is required. Overall, it occupies a smaller space for installation.
    • ・It allows for high-load operation.
    • ・High efficiency in membrane volume
  • Energy saving
    • ・The original element structure allows for membrane separation at low pressure.
    • ・Power cost can be saved with suction filtration or gravity filtration.
    • ・The reinforcement frame of the element enhances durability and allows for long operation.
  • Easy maintenance
    • ・Precision filtration ensures consistency in the quality of treated water.
    • ・The membrane surface is cleaned by aeration, which helps maintain the filtration's performance for a long period.
    • ・Each element is disposable and replaceable. It is easy to handle.
  • High-concentration operation
    • ・The membrane module allows for operation in highly concentrated liquid more than the hollow fiber membrane does.
    • ・It can also be used to condense sludge.

Immersion and membrane separation system

Yuasa immersion membrane module involves immersing a membrane element in water in the tank and filtering it by suction and gravity. On the membrane surface, suspension particles form a dynamic filter layer. Furthermore, the aeration cleaning from the bottom of the tank prevents membrane blockage and thus allows for long operation in high-concentration wastewater.
