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...

Parametric stress distribution in 3D printed polymer quadric-surfaced sludge digesters (2018)
Presentation / Conference
Ramroop, N., Tota-Maharaj, K., & Anoyatis, G. (2018, June). Parametric stress distribution in 3D printed polymer quadric-surfaced sludge digesters. Paper presented at 5th International Association of Hydro-Environment Engineering and Research (IAHR) Europe Congress-New Challenges in Hydraulic Research and Engineering, University of Trento, Italy

The stresses developed in the shell of the quadric surfaced sludge digester, vary according to the height-to-diameter ratio. The optimum dimensions of a 3D printed polymer digester due to hydrostatic loading is evaluated through finite element analys...
