Other variants of activated sludge and SBR technology are available from Bio-Bubble. Site surveys, assessment and recommendations can be undertaken and put forward to meet process requirements. Typical applications include complete new treatment systems or refurbishment of existing works.

Bio-Bubble SBR-EA and SBR-AS imparts alternative process variations to Advanced-Aeration and can be applied to suit various outfall consent limits, provide partial or high rate treatment, or meet prerequisite requirements for discharges to sewers.

Bio-Bubble SBR-EA and SBR-AS both operate with higher intensities of incoming flows and loads although, they have similar batch reaction programmes as Advanced-Aeration which has a well proven record of reliability to suit various applications.
