Our Technologies

  • Tank-Submerged Type Ceramic Filtration System
    This system adopts ceramic membrane, which is durable and chemical resistant. Therefore, the lifetime is longer than organic membranes and replacement cost can be saved drastically. This tank-submerged type enables hybrid process using the tank for both physical and chemical reaction.
  • Endless Filter Cloth Travelling Filter Press
    Changing the filter cloth can be done by winding device, drawing in the new cloth to the machine at the same time as reeling off the old cloth. This mechanism greatly reduces the maintenance work load and human resources. Raking off the cake is also unnecessary. High performance and its compact size are also one of the features of this filter press.
  • Low head loss diffuser (K-membrane)
    Kubota's own membrane material and unique slit design achieved high oxygen transfer efficiency with low head loss (6kPa). Able to install at same depth as ceramic diffusers and reduce energy consumption (down 15~20% from conventional membrane diffuser). Able to replace only aeration sheet.
