I am researching on the challenges of managing sludge from Waste Stabilisation Ponds as compared to those of Activated Sludge Plants and other conventional wastewater treatment systems used in developed/developing countries. What are the grey areas to look out for by new research? Can anyone share experiences from the field, as well as relevant material with data on process design, operational and economic performance monitoring and retrofits?

.Sludge are treated by natural occurring processes and the influence of solar light, wind, microorganisms and algae. The anaerobic pond is the primary treatment stage and reduces the organic load in the wastewater. For facultative ponds sludge removal is even rarer and maturation ponds hardly ever need desludging. Sludge can be removed by using a raft-mounted sludge pump, a mechanical scraper at the bottom of the pond or by draining and dewatering the pond and removing the sludge with a front-end loader
I will be speaking on this topic at the European Biosolids and Organic Resources conference holding at Leeds, UK from 20 to 22 November 2017. You can find the details of the event through the link below.
