“…430, of 13 May 2011 [40], establishes a maximum value of 120 mg L −1 of O 2 , emphasizing that the established limit can only be exceeded if the treatment system has minimum BOD removal efficiency of 60% from the effluent. Mendonça et al [47] reported that the Rosa Elze STP has an average efficiency of 79%. Therefore, the mean values of the results obtained for 53.70 and 59.04 mg L −1 of O 2 for treated wastewater and water filtered with biochar, respectively, met the Complementary Resolution No.…”

The objective of this study was to evaluate the adsorption capacity of orange pomace biochar, applying its benefits in irrigated agriculture. For this, a low-cost system for tertiary treatment using biochar was developed. The objective was also to compare the physicochemical and microbiological attributes of irrigation water with the limits established by the legislation. The impacts of wastewater from the filtration system on the soil and on the agronomic and biological characteristics of the lettuce crop were assessed. Biochar was produced in a muffle furnace and characterized by thermogravimetry and scanning electron microscopy (SEM). The experimental design was randomized blocks, in a 5 (irrigation depths) × 5 (combinations of water sources and fertilization) factorial arrangement, with three replicates. It was found that the use of biochar as a filter material improved the microbiological quality of wastewater. The water sources used in irrigation did not cause changes in soil salinity. Fertigation using wastewater that passed through the filtration system positively affected the agronomic characteristics of lettuce, with no need for top-dressing fertilization. Lettuce leaves produced in the experiment were acceptable for human consumption, according to the standards of Resolution-RDC No. 12, of 2 January 2001, of the National Health Surveillance Agency (ANVISA).

The use of treated wastewater for agricultural purposes can be an alternative to maintaining the quality of water bodies and the biota of natural systems. It can also reduce the demand for water and preserve water supplies for more important uses. This study aimed to evaluate the effects of wastewater reuse in the microbiological quality of above ground parts of sunflower crops. The experiment was conducted from July to September 2012 in the greenhouse of the Department of Agricultural Engineering (DEA) at the Federal University of Sergipe, São Cristóvão Campus. Treated wastewater was collected at the Sewage Treatment Plant (WWTP) Rosa Elze, located in the municipality of São Cristóvão, SE. Irrigation was performed using different ratios of water and treated wastewater. The irrigation followed the FAO 56 method. We used a completely randomized design (CRD) with five treatments and four replicates per plot. The data were analyzed according to the parameters recommended by Resolution no. 12, 02/01/2001 of the Brazilian National Agency for Sanitary Vigilance. Coliforms, E. coli, yeast and mold, and Salmonella were counted. Results have shown that the microbiological quality of the superficial area of sunflower crops analyzed met the standards of Brazilian law. However, further studies should be conducted to investigate the effects of soil
