Thrust 3: Wastewater and Effluent Treatment
and Reuse Technology
This thrust focuses on the development of technologies
and systems that optimise the full wastewater and
sanitation services chain in the municipal (domestic)
sector. This includes the reticulation, treatment and
management of the residues. The challenge is to
implement fitting solutions for a particular application
that will remain functional throughout the intended life
span of the installed infrastructure. This includes the
responsible management of the wastewater sludge and
faecal sludge that is generated. The need for innovative
technologies and solutions is recognised as we prepare
for the future – achieving more stringent effluent
discharge standards, developing acceptable
non-waterborne sewerage solutions, reliable treatment of
ever increasing high strength domestic wastewater,
informing future policy, etc.
|
Programme 1: Emerging
treatment technologies |
|
It
is imperative to develop technologies which can
achieve future policy objectives and stricter
standards. It is also recognised that research
generates information which could inform future
policy. This programme encourages the development
of technologies to address the future anticipated
municipal waterborne sewage and sanitation needs
as well as support government by informing future
policy. It supports development of technological
solutions addressing amongst others: re-use,
recovery, non-waterborne sewerage solutions,
greywater management, peri-urban sanitation
solutions, high strength effluent treatment,
industrial and domestic effluent co-treatment etc.
It also supports research aimed at informing
future policy through data interpretation,
projections, risk assessments, addressing emerging
pollutants, predictive models, etc. |
|
Programme 2: Application of
appropriate technologies and tools |
|
This programme addresses the improvement and
innovative application of existing ‘fit for
purpose’ technology for waterborne sewage treatment
and on-site sanitation. The objective is to
optimise appropriate application to consistently
achieve strict standards with added benefits such
as cost saving, ensuring ease of operation and
maintenance, and improving reliability and energy
efficiency. The integration of social and local
economic development objectives is encouraged. The
programme further focuses on the technical
sustainability of wastewater treatment and
sanitation services by critically appraising
existing policy (including effluent discharge
standards) and impacts. |
|
Programme 3: Stormwater and
sewerage systems |
|
The programme supports the strategic and technical
aspects of managing stormwater and sewerage and
impacts in urban, peri-urban and rural contexts.
The development of generic stormwater and sewerage
planning and technology selection, design and
maintenance tools is encouraged to address current
needs. In order to address anticipated needs, the
programme supports research focussing on improved
technology including water sensitive urban design
(WSUD) and stormwater reuse. It will cover
aspects of technical design, operational,
maintenance, refurbishment and management aspects
of stormwater and sewerage reticulation systems,
to provide sustainable infrastructure in the
extended delivery of sanitation services as a
national priority. |
|
Programme 4: Wastewater
sludge and faecal sludge management |
|
All wastewater treatment and on-site sanitation
facilities generate a solid/sludge that needs to
be managed responsibly. This programme focuses on
research dedicated to improve wastewater sludge
and faecal sludge management practices. Research
on characterisation, emerging technologies and
solutions, anaerobic processes for stabilisation,
minimisation, stabilisation, dewatering,
disinfection and beneficiation is encouraged.
