This book provides basic knowledge about the technology to non-technical project managers in order to enable them to adapt the technology locally.
The book wants also to help the technical specialist 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.
Also, the book is designed 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.
NOTE: This 1998 publication recommends for ABRs a maximum upflow velocity of 2 m/h, which is not recommended anymore by BORDA, the new value is max. 1 m/h (see page 80, first sentence, third line).
