make a conceptual map in spanish, Domestic wastewater treatment in rural areas is important for preventing pollution of aquatic environments and for sanitation.. Due to the high cost of building sewerage systems in rural areas and developing countries, In these situations, on-site wastewater treatment systems are preferred.. Treatment systems have been applied, as percolator filters, muds activated, septic tanks, membrane bioreactors, Constructed wetlands and ponds for on-site wastewater treatment.5–8]. Anaerobic technologies are at the core of sustainable decentralized wastewater treatment systems [9-12]. Interest in anaerobic systems, which has traditionally been perceived, It is due to the simplicity of the process, low operating costs and independence from electricity. The need for energy conservation and CO2 emission reduction potentials. are the main driving forces for the application of anaerobic technologies in recent environmental engineering trends [13]. Developing countries lack adequate wastewater collection and treatment facilities, especially in rural areas. Centralized collection and treatment systems are apparently too expensive and complex to solve your wastewater problems. In the U.S, Around 60 million people use some form of on-site wastewater treatment system, Of which around 20 million use the conventional septic tank system.14]. Australia is no different, where around 12% de la población utiliza sistemas de septic tanks para deshacerse de sus aguas residuales [15]. in Canada, Decentralized systems are used in several locations. Around the 14th% of the population of Greece could receive system services
