Performance Evaluation and Suggestions for Improvement for four existing Wastewater Stabilization Pond Systems in Lesotho

vom 10.11.11

Verfasser: Martin Beckhoff

Project Scope

This thesis intends to evaluate the treatment performance of four waste stabilization pond (WSP) systems in Lesotho. The performance evaluation is based on recorded wastewater samples and surveyed pond dimensions. Tracer studies were executed to quantify the extent of hydraulic shortcircuiting in different ponds. Flow measurements allowed an estim ate of current pond retention times. [...]
