Treatment
of tapioca processing industrial wastewater in
Southern Vietnam
In
tropical zones, surface
water is often the only source for drinking and industrial water
supply. However, due to
numerous discharges of untreated wastewater, water bodies
are often highly contaminated. The main objective of this project is to
develop procedures and
techniques to sustainably improve the water quality of polluted surface
waters
in tropical and subtropical zones under given socio-economic and
ecological
constraints. This includes
experimental studies of tapioca wastewater treatment and the
application of numerical simulation
techniques to the water
cycle and water quality.
A
treatment concept has
been developed that consists of a
mechanical and chemical
pretreatment, followed by anaerobic degradation, and post-treatment in
vertical subsurface
flow constructed wetlands. Using a pilot plant, this innovative process
combination
will be adapted and optimised. The results of this
wastewater treatment will be integrated into a numerical water
pollution control
management system (WPC- MS) of the area around the pilot
plant (Dongnai river basin).

Perspectives,
approaches and ideas for further development
at the EU level
Wastewater
treatment in developing countries (and countries in transition) is a
global scientific problem that necessitates cooperation
between local authorities and international partners. Establishing a
network
with universities, organisations, and municipalities on a European
level should
facilitate the dissemination and transfer of the project results to
other
settings.
Development
of a comprehensive water pollution control rnanagement system in
industrialised
countries will provide a valuable tool for planning purposes in other
parts of
the world.
Working
together with international partners will allow them more easily gain
access to
the European Research Area (ERA) and could result in a higher level of
research
mobility and knowledge exchange ('brain circulation').
