Features Remarkably Small Footprint: The KUBOTA MBR process requires less aeration
tank volume than a CAS process, and does not require any final clarifier.
 Excellent Permeate Quality: Permeated water from the KUBOTA SMU is highly
treated. You can reuse the treated water for irrigation, toilet flushing etc..

Overview (Technical principles, actions, etc.)
The KUBOTA Membrane Bioreactor (MBR) process is a provenwastewater treatment method which combines a biological treatment
process and a membrane filtration process for final solid-liquid separation
with KUBOTA SMU. This is applied to municipal and industrial wastewater
treatment.

KUBOTA CorporationWater & Environment Planning and Control Dept.
1-3, Kyobashi 2-chome, Chuo-ku Tokyo 104-8307, Japan We offer best shredder solutions that realize simple and low-cost
separation to promote efficient recycling.
 Our shredders process scrap metals and solid wastes, such as waste
home electric appliances, PCBs, turnings, bulky waste, andcombustible/incombustible wastes.
Vertical Shredder: features compound shredding with special hammers andreduces waste materials into small, uniform particle sizes. Its verticalstructure allows for highly efficient reduction of bulky waste.
Single-shaft Shredder: features shear-shredding with rotating and fixed
cutters and employs the shredder-specific special torque limiter to ensure
safe and stable operation.
