Partnership for Urban Resource Recovery (PURR)
Sandec is launching a new research project
to evaluate options for the cotreatment and resource recovery of biosolids from
wastewater and faecal sludge treatment in
five cities in Vietnam.
Context:
One quarter of Vietnam's
population lives in cities, and the urban population is expected to keep
increasing by at least 1 million people annually. Currently, there is no faecal
sludge management for onsite systems, and wastewater sewers and treatment
plants are not sufficiently distributed to provide environmental protection and
sanitation coverage in urban areas. Even if a goal of 80–90% of households
being connected to the sewer by 2020 is met, septic tanks will continue to play
an important role for the remaining 10–20%. A recent survey in Hanoi, Hai
Phong, and Ho Chi Minh City revealed that septic tanks are still the most
widely distributed type of household sanitation system in peri-urban and urban
areas. The faecal sludge from septic tanks needs to be collected, transported
and treated in a safe and adequate fashion in order to provide protection of
human and environmental health.
Objectives:
This project aim to:
- Develop a basic understanding of faecal sludge characteristics, and the potential for anaerobic digestion
- Evaluate co-digestion of faecal sludge and wastewater sludge
- Evaluate the market demand for resource recovery from biosolids from faecal sludge and wastewater treatment
