Brief Description:
Applying advance water treatment technologies such as reverse osmosis (RO) and nano-filtration (NF) has
become a very popular and a feasible strategy to overcome challenges in producing potable and clean
industrial treated water. These high-pressure membrane technologies (desalination processes) are primarily
used for softening and the reduction of TDS in water treatment. They are also capable of efficient removal of a
broad array of micro level contaminants in raw water and secondary treated wastewater. In the recent past, a
significant number of RO and NF water treatment facilities were installed in the dry zone of Sri Lanka. To
operate RO and NF water treatment facilities sustainably, brine or concentrate management is considered as a
critical process. The discharge of brine consisting of a complex array of minerals/salts from desalination
processes poses a significant threat to the environment. Further, brine solutions produced from these systems
are considered as a valuable source of resources which could attract a significant revenue to make these
processes sustainable. In recent past, a several research groups across the world studied the potential of
recovering the valuable salts/minerals from brine/concentrates from these high-pressure membrane plants.
However, the suitable resource recovery technologies could be different depending on many factors such as
the mineral/salt composition, production rate (quantity), location/region of the plant, etc. Therefore, this study
focuses on the following:
1. Conduct a thorough literature review to gain the background knowledge on this research area and
understand the possible technologies that could be applied in developing countries.
2. Carry out a comprehensive field survey to understand the status and the operating practices of RO and NF
treatment facilities installed in Sri Lanka.
3. Design and operate a suitable cost-effective lab/pilot scale brine management process (Membrane
Distillation) to investigate its sustainable operation.
4. Perform a life cycle (feasibility) analysis to find the applicability of the selected brine management
technology for operating RO and NF treatment facilities installed in Sri Lanka sustainably.

Brief Description:
Adopting supplementary cementitious materials (SCMs) to reduce clinker usage in cement has been the
most successful strategy to control greenhouse gas emission in building and construction sector to date. In
recent years, the emergence of calcined clay and integration with other SCMs have further enhanced
construction sustainability, due to the general availability of clay and high potential cement substitution rate.
In particular, flash calcined clay, manufactured by flash calcination for only a few tenths of a second, can
diminish up to 80% of energy required for Portland cement production. However, as a newer construction
material in the market with strong implications on sustainability, understanding the long-term durability
performance of calcined clay concrete manufactured using locally sourced clay is essential, yet an effective
and systematic method is extremely lacking. Herein, focusing on marine exposure condition where
combined deterioration mechanism may occur, the goal of this project is to develop a robust computational
framework for assessing the aging resistance of calcined clay concrete, so as to promote optimal design
using local source materials. In specific, four main objectives are: Mineralogical analyses on calcined clay
concrete pre-mixed with chloride and sulfate salts; Physics-based reactive transportation analyses on
calcined clay concrete under standalone deterioration mechanisms of progressive chloride ingress and
sulphate attack; Durability assessment on calcined clay concrete under combined chloride-sulphate attack;
and investigation on the influence of clay and blend compositions on the durability performance of calcined
clay concrete against marine exposure.

Emission of greenhouse gases (GHG) from aquatic and terrestrial ecosystems inevitably has a major impact on global climate. Major efforts on monitoring and quantifying GHG fluxes are based on the measurements with eddy covariance and closed chamber techniques. The measured data are then used to calibrate the models that estimate global GHG budgets.
However, the measurements of GHG emissions are largely concentrated only in one part of the world, mostly in North America and Europe, whilst the low and middle-income countries in the Global South, including South-East Asia, remain largely underrepresented. Unfortunately, these countries have emerging environmental problems with increasing population and rapid changes in land-use patterns. Lack of funding for research, technical and technological incompetency, and political uncertainties are among the major factors leading to very limited measurements in these underrepresented countries. Consequently, the specific role of GHG emissions from these regions has been considerably downplayed in the global GHG budget.

Brief Description:
The growing concern about global climate change and its adverse impacts on
societies is putting severe pressure on the construction industry as one of
the largest producers of greenhouse gases. Given the environmental issues
associated with cement production, Geopolymer/Alkali Activated Concrete has
emerged as a sustainable construction material. Many research studies have
been conducted during recent years on the topic of geopolymer/alkali activated
materials based on the engineering performance of the concrete although the
commercialisation is limited. What has been missing is the combination of
this research in a way that would provide a simple to use design tool for
geopolymer/alkali activated concrete as a replacement to concrete based on
Portland Cement. This research project will address this requirement by developing
a standard mix design method and guideline for geopolymer and alkali activated
concretes using Advanced machine learning techniques, namely Artificial Neural
Network (ANN), Multivariate Adaptive Regression Spline (MARS) model and Support
Vector Machine (SVM) techniques. Outcomes of this research will deliver significant
benefits in terms of environmentally friendly concrete to the construction
industry.

Brief Description:
Over 100 milions tonnes of glass are produced annually in worldwide, but
only 21% is recycled. Recycled glass has been used in the construction industry
for several decades as construction material. However, there is an increasing
need to reuse this waste material which have high economic value if utilized
through novel recycling principles. A new technology was recently developed
at RMIT using glass wastes and can be highly versatile with potential applications
in various construction fields such as access covers, cladding systems,
interior and exterior walls, retaining walls and road infrastructure products.
The new technology that utilizes 65% of glass wastes has been proven to
be structurally effective and this project will translate the technology
to identify applications in retaining walls, acoustic panels and claddings.
The project will utilize modelling and analytical tools in order to optimize
the use of new glass recycling technology by proposing geometric and structural
design requirements satisfying relevant building standards. The project
outcomes will be commercialized by the industry partner through patents/IP
protection that will add significant value to glass fines through application
into sustainable civil engineering constructions.
We are looking for a dynamic candidate who meets the above qualifications.

A Research seminar on "Non-structural Cracking of Concrete : Causes and Mitigation" by Dr. H.D. Yapa will be held on 27th January 2021, from 11.00 a.m. to 12.00 p.m. at EOE Pereira Theatre, Faculty of Engineering, University of Peradeniya
Concrete is an exceptional construction material. It is strong/stiff in compression, durable, economical, etc., however, is weak in tension. Consequently, reinforcement is required wherever in structural regions with tensile stresses. Even with the use of reinforcement, total prevention of concrete cracking is hard to achieve, so generally the objective of the designer is to control of cracking. Undoubtedly, cracking is undesirables for concrete in terms of serviceability, durability, and aesthetic perspectives. The causes for triggering tensile stresses (and cracking) in concrete structures are not only of external loads, but also of numerous non-structural roots (e.g. shrinkage, creep, thermal expansion) owing to heterogeneous characteristics of concrete. It is however common that structural cracking is only taken seriously by the designer and consequently the structures suffer with numerous non-structural cracking issues. In this light, the talk discussesinto the main causesof non-structural cracking of concrete and into potential meansof mitigation.

A Research seminar (ONLINE) on "Role of Water Engineers in CKDu Affected Areas: A Research Perspective" by Dr.(Mrs) K.G.N. Nanayakkara will be held on 30th December 2020, from 2.00 pm to 3.00 pm.
Chronic Kidney Disease of Unknown Etiology (CKDu) has been affecting Sri Lanka since 1990s and the affected area is ever increasing. The disease mainly affects the health of the people, but creates more socio-economic problems, leaving otherwise productive people helpless. Although the exact reason behind the disease is yet to be identified, the strongest hypothesis is the deteriorating quality of drinking water. The responsible organizations have been seeking for solutions and a substantial amount of research have been conducted in the country on CKDu. Providing good quality drinking water by using membrane-based treatment plants is one of the measures taken by various authorities. However, there are many issues related to the operation of such community based plants. In our research, we have monitored water treatment plants situated in CKDu affected areas for their performance and associated problems. Alternative water sources such as rainwater was also investigated. The people residing in areas fed by treated pipe-borne water supply also showing concerns in consuming treated water, making the situation even worse. The thorough investigation of the surface and groundwater sources, treatment plants and alternative water sources unveil new fundamental research ideas, leading to conducting basic research to provide better quality water. The presentation will cover the findings of applied and basic research, emphasizing the need of immediate research inputs from water engineers to ease the situation.

Prof. Ranjith Dissanayake and the team received the research grant for “Strengthening University-Enterprise Collaboration for Resilient Communities in Asia (SECRA)” from the European Commission through the Erasmus+ program Capacity Building in Higher Education
The overarching aim of SECRA is to contribute to more resilient communities in Asia through institutionalized, systematic, monitored, innovative, and inclusive university–enterprise collaboration (UEC) in climate change action and disaster resilience (DR). The main problem targeted by SECRA is the ad hoc, episodic quality of UEC in the field of DR in many Asian countries, which are disproportionately affected by consequences of climate change. We are aware that there is no simple answer to the wickedness of climate change consequences or resilience; we are claiming, however, that facilitating systematic, institutionalized, inclusive (in terms of gender parity) and monitored UEC is part of a solution. High quality, entrepreneurial collaborative activities between universities and industry facilitate the exchange of scientific knowledge, practical skills and good practices, which otherwise remain siloed.
SECRA deals with the problem at hand in a sequential fashion. The project’s contribution to more resilient communities is through increasing the capacity of Higher Education Institutions (HEIs) to initiate, manage, maintain, and benefit from UEC. The institutionalization and systematization of UEC are addressed in WPs 1, 2, and 3, innovation in WP4, and monitoring in WP5. SECRA will produce, inter alia, material towards eventual change of policies governing collaborative activities in partner countries; a relation framework to understand UEC; an online platform for a Community of Practice (CoP) consisting of HEIs, public sector and enterprise actors; a corporate start-up lab and networking activities in partner HEIs, and a monitoring tool to assess the quality of UEC that can be broadly contextualized for use in HEIs worldwide.
