“…The highest concentration (lower than proposed threshold concentrations for carcinogenicity) was recorded for phenathrene. Boyden and Rababah (1996) assessed the recycling of nutrients from settled primary domestic wastewater (not disinfected) to produce value-added crops including capsicum and tomato. The crops grown in these systems considerably removed nitrogen and phosphorous from settled primary sewage, and appeared healthy compared to the control using commercial nutrients.…”

“…When comparing the mean values of total nitrogen, total phosphorus, potassium, calcium, magnesium and sulfur present in the wastewater with the values proposed by Martinez and Silva Filho (2004) (Table 2) for hydroponic cultivation, these are insufficient to be used as nutritious solution for the lettuce culture, and a nutrient supply is necessary. Lettuce plants can extract approximately 77% of the phosphorus and 80% of the nitrogen contained in the wastewater solution from sanitary sewage (Boyden and Rababah, 1996), but they present a reduction of more than 50% in their fresh mass (Cuba et al, 2015;Boyden and Rababah, 1996), with the inadequate concentration of nutrients in wastewater being the main factor.…”

The aim of this research was to evaluate the nutrient absorption and the fresh mass of lettuce plants cultivated using domestic wastewater in a hydroponic system during winter and summer seasons. The hydroponic system used was the Nutrient Film Technique with three treatments: 1) drinking water and chemical fertilizers (T1): 2) wastewater supplemented with chemical fertilizers (T2): and 3) only wastewater (T3) in a completely randomized experimental design with four replicates. The wastewater was previously characterized before being used in the treatments in order to quantify the need for nutrient supplementation in the T2 treatment. To determine the fresh mass, dry mass and nutrient absorption, three whole plant samples of each plot were collected at 1, 7, 14 and 21 days after transplanting. The nutrient absorption occurred according to a growing polynomial function for all treatments and most of the elements throughout the two cycles of the crop, except for potassium and magnesium in the T3 treatment in the winter crop. The results of fresh mass of the plant, pH and electrical conductivity of nutrient solutions were submitted to 2-way ANOVA, considering winter and summer as the first factor and treatments as the second one. A significant interaction between the factors for fresh mass and electrical conductivity was observed, and for that reason the average were submitted to Tukey test (p < 0.05%). For T1 and T2 treatments, significant differences were found between the average of the fresh mass of winter and summer, with higher values in winter. For the T3 treatment, no difference was found between the evaluated periods, but there was a significant difference in relation to the other treatments in both periods. The plants of this last treatment had lower fresh mass, less accumulation of nutrients and visual symptoms of nutritional deficiency. Under the experimental conditions, it was concluded that there was no difference in the nutrient absorption between the T1 and T2 treatment, but in the T3 treatment, the absorption was slower and smaller, demonstrating that it is necessary to supplement the wastewater with nutrients.

“…In this case, pre-treatment with planted sand filters followed by UV radiation should be considered [11]. This approach was already tested; lettuce and capsicum indeed are able to utilize nutrients from municipal wastewaters [12].…”
