Modelling of quadratic-surface sludge digesters by smoothed particle hydrodynamics (SPH) – Finite element (FE) methods (2020)
Journal Article
Tota-Maharaj, K., Nounu, G., & Ramroop, N. (2020). Modelling of quadratic-surface sludge digesters by smoothed particle hydrodynamics (SPH) – Finite element (FE) methods. Archives of Hydro-Engineering and Environmental Mechanics, 67(1-4), 35-53. https://doi.org/10.1515/heem-2020-0003

The quadric-surfaced sludge digester (QSD), also known as the egg-shaped sludge digester, has proven its advantages over traditional cylindrical digesters recently. A reduction in operational cost is the dominant factor. Its shell can be described as...

Numerical modelling of Quadric-Surfaced Sludge Digesters (QSD) within Wastewater Infrastructure using 3D Printing Techniques (2020)
Journal Article
Tota-Maharaj, K., & Ramroop, N. (2020). Numerical modelling of Quadric-Surfaced Sludge Digesters (QSD) within Wastewater Infrastructure using 3D Printing Techniques. Institute of Water Journal, 25-31

The quadric-surfaced sludge digesters (QSDs), sometimes referred to as egg-shaped sludge reactors, are becoming more popular within wastewater treatment works as of recently. These tanked systems with their shell structure provide a surface free of d...

3-parameter log-logistic distribution modelling and scenario development to evaluate the United Kingdom’s water demand (2020)
Journal Article
Surendran, S., & Tota-Maharaj, K. (2020). 3-parameter log-logistic distribution modelling and scenario development to evaluate the United Kingdom’s water demand. Institute of Water Journal, 4-9

A major unresolved problem in water consumption modelling is the identification of a statistical distribution function which best represents the random nature of water consumption patterns. Relatively, few studies can be found in the literature in wh...

Comparing the long term clogging pattern of permeable pavements for stormwater treatment and reuse (2020)
Presentation / Conference
Tota-Maharaj, K., & Monrose, J. (2020, February). Comparing the long term clogging pattern of permeable pavements for stormwater treatment and reuse. Paper presented at 2nd Polish IWA Young Water Professionals Conference “Emerging Technologies in Water and Wastewater Sector”, Warsaw University of Technology, Warsaw, Poland

Permeable pavements are engineered to temporarily store water to reduce flooding during rainfall events. Permeable pavements are distinguished primarily based on their surface materials which can vary from concrete, asphalt, plastic or stones. This p...

Feasibility of decentralised Sustainable Refugee Camp Drainage System (SRCDS) (2020)
Presentation / Conference
Tota-Maharaj, K., Ajibade, O. O., Hills, C., & Macleod, C. (2020, February). Feasibility of decentralised Sustainable Refugee Camp Drainage System (SRCDS). Paper presented at 2nd Polish IWA Young Water Professionals Conference “Emerging Technologies in Water and Wastewater Sector”, Warsaw University of Technology, Warsaw, Poland

In this research, a new decentralised drainage system, Sustainable Refugee Camp Drainage System (SRCDS), is developed for effective management of storm water and greywater in Dadaab refugee camp, Kenya. The SRCDS uses the principle of Best Management... Read More about Feasibility of decentralised Sustainable Refugee Camp Drainage System (SRCDS).
