It is an amazing course, I enjoyed quite new topic soo far and I loved the way of teaching of mentors in course. Thank you coursera for giving me an opportunity to better understand the new knowledge.
It was an excellent learning opportunity with a new challenging field of research. I am keen to register more subjects in the future in related subjects under your mentoring. RegardsDr. Bhaskar Das

I learn more from this course such as how mange project, how I understood key concepts of project, kind of the wastes, how treated them and how can I benefitfrom then such as use them as composetion. Finally, Thank very much to all instructors or anyone contributes in preparing this course to content all these information that really gain more to background

The course is well structured. I missed some steps in the overall faecal sludge treatment because I never studied it before. I think it should be helpful to give a process flow diagram of the entire treatment. I also missed some treatment objective detailed explanation, for example, of pathogen inactivation.

Provided a great overview of the topic. Great support for a manager trying to gain perspective on the complexities of FSM and sanitation systems.

The lectures handled were simple and easily understandable. It would have been more useful, if a few more case studies would have been included.

It provides insights into the technological gaps in the waste management system encountered in developing countries.

Unplanted sludge drying beds are shallow filters filled with sand and gravel with an under-drain at
the bottom to collect leachate. Sludge is discharged onto the surface for dewatering (Figure 7.1). The
drying process in a drying bed is based on drainage of liquid through the sand and gravel to the bottom
of the bed, and evaporation of water from the surface of the sludge to the air. The design as well as the
operation of the drying bed is fairly straightforward, provided the sludge loading rate is well selected
and the inlet points for depositing the sludge onto the bed are properly designed. Depending on the
faecal sludge (FS) characteristics, a variable fraction of approximately 50-80% of the sludge volume
drains off as a liquid (or leachate), which needs to be collected and treated prior to discharge (Tilley
et al., 2014). After reaching the desired dryness, the sludge is removed from the bed manually or
mechanically. Further processing for stabilization and pathogen reduction may be required depending
on the intended end-use option. When considering the installation of a drying bed, the ease of operation
and low cost needs to be considered against the relatively large footprint and odor potential.
