Kubota MBBR Biological

The Kubota Johkasou Moving Bed Biofilm Reactor (MBBR) is compact, lightweight, and easy to transport and install.

MBBR (Moving Bed Biofilm Reactor) is an efficient biological wastewater treatment system perfectly suited to Australian and Pacific wastewater requirements. It is applicable for daily usage ranging from 5kL to 500kL and has the capability to expand as necessary.

It offers advanced treatment with key advantages that include simple operation, low costs, compact footprint, and high reliability. MBBR also features multiple advanced treatment chambers in a single tank; a design innovation that consistently achieves top-quality wastewater treatment (20/20) while minimising costs, visual impact, and odours.

The Kubota MBBR is internationally accredited and adheres to strict (ISO) quality standards and control processes. The system operates autonomously, but depending on the application, maintenance is required at 60 or 90-day intervals. MBBR is backed by 50 years of Japanese wastewater research and development – making it a proven technology and the world’s leading commercial system.
