TL;DR: Well designed baffles thus have considerable potential for reducing pond area requirements and hence costs in the hot tropics and the need for field studies on baffled pond systems to validate (or allow calibration) of the CFD model used in this study.

TL;DR: Aerated and unaerated rock filter performance for BOD, SS, nitrogen and faecal coliform removals is described and compared, and the land-saving opportunities as maturation ponds and reedbeds become redundant are highlighted.

TL;DR: A pilot-scale experiment tested the effect of hydraulic retention time on primary facultative pond performance whilst keeping the BOD loading constant, finding that no significant loss of performance was experienced at the test range for BOD and ammonia removal; some loss in SS removal was noted at 20 days' retention time.

TL;DR: It is recommended that new waste stabilization pond (WSP) systems be designed for compliance with a given E. coli effluent requirement by the classical procedure and that existing overloaded WSP systems be upgraded using the modern procedure.
