MMBR small community system

The Moving Bed Biological Reactor (MBBR) wastewater treatment plant incorporates the primary and secondary stages of wastewater treatment, using the mechanical aeration process housed within concrete tanks to achieve a 20:30 standard (mg/l BOD:mg/l TSS).

The MBBR system is a robust package treatment plant that offers simplicity of design, installation and operation and can be designed for small to large populations.

The concrete tanks of the MBBR provide an additional system design option for customers. Among other site conditions, concrete tanks are particularly suited for use where a deep invert level is required.

The MBBR treatment process can be provided for new sewage treatment works or for retrofitting or upgrading existing wastewater treatment plants where a higher treated effluent standard is required.

Nutrient removal options are also available. We provide Tertiary treatment options where higher consent levels need to be met.
