| Abstract |
The aim of this work was to evaluate the performance of a plant palette for treating light greywater (LGW) in a nature-based solution (NbS). Different layers of filter media (soil, granular activated carbon, zeolite, sand, and gravel) were packed in containers in conjunction with one of the following plant species: Chrysopogon zizanioides, Portulaca grandiflora, Tradescantia pallida, Nephrolepis obliterata, and Sansevieria trifasciata. The containers were fed weekly with 500 mL of LGW for eight weeks. The infiltrated water was recovered to test its quality against that of the LGW in terms of turbidity, electrical conductivity, COD, ammonia nitrogen, and phosphates. The quality of the effluents treated with C. zizanioides, P. grandiflora, and T. pallida complied with the specifications established by Mexican regulations for water being reused for infiltration purposes, so an SbN using the proposed plan palette could be optimized to promote a circular water economy at the household level. |
