Cost comparison of full-scale water reclamation technologies with an emphasis on membrane bioreactors

Abstract: The paper assesses the costs of full-scale membrane bioreactors (MBRs). Capital expenditures (CAPEX) and operating expenses (OPEX) of Spanish MBR facilities have been verified and compared to activated sludge plants (CAS) using water reclamation treatment (both conventional and advanced). Spanish MBR facilities require a production of 0.6 to 1.2 kWh per m, while extended aeration (EA) and advanced reclamation treatment require 1.2 kWh per m. The energy represents around 40% of the OPEX in MBRs. In terms of CAP… Show more

“…It takes as an input the system scale (people in residential and commercial buildings to be served) and calculates the manufacturing and operating requirements for the treatment unit for that scale. The impacts are based on published data describing wastewater treatment (we assumed a membrane bioreactor, MBR) capital and operation requirements at different scales and are expressed by polynomial equations for economic costs and energy intensity (equations S1-S5 in the SI) [5,24]. The GHG emissions for the operation and manufacturing are estimated based on the technology selection and energy performance curve (equation S5 in the SI) (assuming all energy use is in the form of electricity) as calculated by the authors in previous work [5].…”

“…Foram considerados os principais contribuintes para o custo de operação de biorreatores a membrana no cálculo do OPEX do BRM proposto, caracterizados pelo consumo energético e reposição periódica de membranas (IGLESIAS et al, 2017;JUDD, 2017;YOUNG et al, 2013), além da folha de pagamento de funcionários (YOUNG et al, 2012(YOUNG et al, , 2013…”

“…É importante ressaltar que os custos de transporte e cloração da água de reúso devem ser considera-dos quando se realiza tal prática, o que aumentaria o OPEX. Contudo, o transporte da água de reúso até o local desejado incrementa em torno de 0,02 -0,04 €/m³ no OPEX (IGLESIAS et al, 2017), e a sua desinfecção com cloro representa menos de 3% dos custos de operação (VERRECHT et al, 2012). Portanto, a aplicação de BRM na produção de água de reúso em Santa Catarina é uma escolha interessante, tanto do ponto de vista econômico como do ambiental, uma vez que o estado possui polos industriais distribuídos em diferentes regiões, bem como demandas públicas e comerciais de água.…”
