A consistent modelling methodology for secondary settling tanks in wastewater treatment.

The aim of this contribution is partly to build consensus on a consistent modelling methodology (CMM) of complex real processes in wastewater treatment by combining classical concepts with results from applied mathematics, and partly to apply it to the clarification-thickening process in the secondary settling tank. In the CMM, the real process should be approximated by a mathematical model (pr...

Settling-Thickening Tanks

Settling-thickening tanks are used to achieve separation of the liquid and solid fractions of faecal sludge (FS). They were fi rst developed for primary wastewater treatment, and for clarifi cation following secondary wastewater treatment, and it is the same mechanism for solids-liquid separation as that employed in septic tanks. Settling-thickening tanks for FS treatment are rectangular tanks,...

Semi-Implicit Time-Discretization Schemes for the Bidomain Model

The bidomain model is a system of partial differential equations used to model the propagation of electrical potential waves in the myocardium. It is composed of coupled parabolic and elliptic partial differential equations, as well as at least one ordinary differential equation to model the ion activity through the cardiac cell membranes. The purpose of this paper is to propose and analyze sev...

Honduras Wastewater Treatment: Chemically Enhanced Primary Treatment and Sustainable Secondary Treatment Technologies for Use with Imhoff Tanks

Wastewater treatment within Honduras is indicative of the state of water and sanitation services throughout the developing portions of Central America. One technology which comprises approximately 40 percent of all treatment facilities within Honduras is the Imhoff tank. First patented in 1906 the Imhoff tank has long been out of favor within the developed world as newer technologies and large ...
