Integrated wastewater management for health and valorization : a design manual for resource challenged cities

Integrated wastewater management for health and valorization a design manual for resource challenged cities

Adequate wastewater treatment in low to medium income cities worldwide has largely been a failure despite decades of funding. The still dominant end-of-pipe paradigm of treatment for surface water discharge, focusing principally on removal of organic matter, has not addressed the well-published prob...
