Decentralised wastewater treatment in developing countries - A handbook by BORDA

This handbook published by Bremen Overseas Research and Development Association (BORDA) is an outcome of a project titled “Low Maintenance Wastewater Treatment Systems - LOMWATS; Development of Technologies and Dissemination Strategies.” This book aims at a target group, which is typical for decentralised technology implementation and consists of people whose knowledge is too general on one hand, or too specialised on the other to master very typical problems which go together with decentralisation.

DEWATS handbook

This book provides enough basic knowledge about the technology to non-technical project managers in order to enable them to adapt this technology locally. The book aims to help the technical specialists to understand where technical simplification is required in order to disseminate the technology in its typical decentralised context - and provides tables for dimensioning of treatment plants on the computer.

The book also aims to assist senior development planners who need to understand the specifics of decentralised wastewater treatment technology sufficiently in order to select or approve appropriate strategies for its dissemination.

The handbook is divided into the following chapters:

1. Foreword
2. DEWATS: properties, performance and scope
3.Dissemination
4. Economics
5. Process of wastewater treatment
6. Ecology and self purification effect
7. Control parameters
8. Dimensioning parameters
9. Technology
10. Sludge disposal
11. Reuse of wastewater and sludge
12. Biogas utilisation
13.Computer spreadsheet
14. Appendix
15. Literature
16. Keywords
