Scope note: Wetlands construidos o sistemas inundados construidos también se conocen como filtros plantados con macrófitas, tierras húmedas construidas y tratamiento por zona de raíces. Es un proceso clasificado como de disposición controlada de las aguas residuales en el suelo. En esa unidad de tratamiento, el afluente aplicado deberá, como mínimo, ser el efluente de tratamiento primario. Son canales o compartimentos rasos excavados en el suelo, impermeabilizados, rellenados con sustrato de grava y arena, en el cual se plantan las macrófitas acuáticas. El flujo de las aguas residuales puede ser superficial, o sub superficial, siendo esta última mejor debido al menor potencial para la generación de olores y para evitar el surgimiento de mosquitos y ratas. Los wetlands construidos de escurrimiento sub superficial se subdividen en cuanto al sentido del flujo hidráulico en horizontales y verticales. (Traducción libre del original: Brasil. FUNASA, 2018)

Tree number(s): SP4.895.141.712.406.960
Scope note: Also known as Macrophytes Floating Filters (MFF), Constructed Wetlands (CW) and also Root Zone Wastewater Treatment (RZWT), it is a process classified as a controlled wastewater ground disposal. In this treatment unit the applied effluent should at least be the post primary treatment effluent. The systems are composed by channels or shallow compartments excavated in the ground, waterproofed, filled with gravel and sand substrate, where the aquatic macrophytes are planted. The wastewater flow may be superficial, or subsurface, the latter having advantage for the lower potential for generation of odours and to avoid the appearance of mosquitoes and rats. The wetlands constructed of sub-surface runoff are subdivided as to the direction of horizontal and vertical hydraulic runoff. (Free translation from the original: Brasil. FUNASA, 2018)
