Energy-saving wastewater treatment systems : formulation of cost functions

Nogueira, R.; Ferreira, I.; Janknecht, P.; Rodríguez, Juan José; Oliveira, Pedro; Brito, A. G.

Natural interactions between water, soil, atmosphere, plants and microorganisms include physical, chemical and biological processes with decontaminating capacities. Natural or energy-saving wastewater treatment systems utilize these processes and thereby enable a sustainable management in the field of wastewater treatment, offering low investment and operation costs, little or no energy consumption, little and ...

Life cycle assessment of wastewater treatment options for small and decentraliz...

Machado, A. Patrícia; Urbano, Lino; Brito, A. G.; Janknecht, P.; Rodríguez, Juan José; Nogueira, R.

There are several methodologies that enable direct comparison of centralized and decentralized sewage treatment systems, both in economical and ecological view. One of the latter is the so-called Life-Cycle Analysis (LCA), which accounts for the environmental impacts of a product, service, or process over the course of its life cycle. Assessed environmental impacts generally include consumption of land, energy,...
