What are MBRs? is a complete practical resource on membrane bioreactors, combining 148 pages of print with a credit-card sized USB of digital tools (MBR xtras) for more extensive knowledge – videos, images, documents and Excel spreadsheet-based calculation aids, data correlations and units conversion.
The pocketbook is an introductory text for anyone wishing to familiarise themselves with membrane bioreactor technology for wastewater treatment. But it also provides more practical specialist content for those already working in the field.
