“…The micronutrients were not altered by the applied treatments (Table 3). Several authors (Prazeres et al, 2014;Herpin et al (2007); Gomes et al, 2009;Becerra-Castro et al, 2015;Azevedo & Oliveira, 2005;Pereira et al, 2011) that have been working with crops irrigated with treated effluents of organic origin, mainly domestic sewage, also obtained similar results for the presence of macronutrients in the soil and a decrease in soil acidity, satisfactory in tropical soils. The sodium values and the percentage of exchangeable sodium in the soil (Table 3) were also higher in treated dairy effluents.…”

“…Research on wastewater of animal origin showed an increase in the percentage of dispersed clay by high salt application (Condé et al, 2013;Erthal et al, 2010). Prazeres et al (2014) evaluated the soil chemical properties in the production of tomatoes irrigated with pretreated and diluted effluent from the cheese industry at different levels of salinity and verified a linear increase in soil conductivity but also achieved increases in productivity.…”

This study was conducted to evaluate the nutritional status of table beet plants cultivated in a greenhouse irrigated with treated dairy effluent at different irrigation depths. The experimental design used was a randomized block in a 3 x 3 + 1 factorial arrangement with four replications and conducted in a greenhouse. The treatments consisted of three types of water sources and three irrigation depths applied by drip irrigation: anaerobic effluent; anaerobic/aerobic effluent; tap water, and irrigation for replenishment 50; 100 and 150% of the crop evapotranspiration (ETc). All these treatments were applied in combination with 50% of the recommended nitrogen fertilization for the table beet cultivation. A control treatment was irrigated with tap water with irrigation depth equal to 100% ETc and received the complete dose (100%) of mineral nitrogen fertilizer. Table beet seedlings were arranged in 40 fiberglass boxes with a base area of 1 m 2 . Table beets were harvested 72 days after transplanting (DAT) when the leaves and roots were analyzed. Irrigation with wastewater promoted appropriate levels of macronutrients, distributed between the leaves and roots. The sodium was increased significantly in the leaves and roots of table beets in effluent treatments at increasing irrigation depths, which was antagonistic to the absorption of potassium.

“…The author also indicated maximum water use efficiency by alfalfa when the alternative irrigation comprised one portion of RWW to be followed by three portions of fresh water. Similar studies on the use of reclaimed industrial wastewater (Prazeres et al, 2014) and domestic wastewater (Aiello et al, 2007;El-Hamouri et al, 1996) were carried out to investigate the impacts of these waters on tomato yield and quality and on soil and environment. Since the earlier studies didn't take into account the optimization of K-use efficiency by irrigated crops, taking into consideration both water shortage and cost of K-chemical fertilizer in one irrigation practice would be of paramount importance.…”

“…No caso da irrigação, atividade responsável por 72% do consumo de água no Brasil (ANA, 2015), a vantagem do reúso é ainda maior, devido à presença de nutrientes nos efluentes com potencial de fertilizante. Estudos mostraram manutenção e até aumentos na produtividade de culturas que foram irrigadas com efluentes (SINGH; DESHBHRATAR; RAMTEKE, 2012;PRAZERES et al, 2014) e também redução na fertilização nitrogenada em relação a dose recomendada (GOMES et al, 2015).…”

No entanto, o efeito desses efluentes nos sistemas de irrigação ainda é pouco estudado. Assim, os objetivos desse trabalho foram caracterizar o efluente de laticínio tratado por processos biológicos, classifica-lo quanto ao potencial de entupimento de emissores e avaliar a uniformidade do sistema de irrigação por gotejamento por meio da determinação dos coeficientes de uniformidade de distribuição (CUD), de Christiansen (CUC) e estatístico (CUE). O delineamento experimental foi em blocos casualizados, em esquema fatorial 3 x 3, com quatro repetições e avaliações dos coeficientes ao longo do tempo. Os tratamentos foram constituídos de três fontes de água: água de abastecimento (AB); efluente de laticínio tratado por sistema anaeróbio (EAN) e por sistema aeróbio (EA); e por três lâminas de irrigação, 50% (W1), 100% (W2) e 150% (W3) da evapotranspiração da cultura da beterraba. Após 40 horas de funcionamento, CUD, CUC e CUE foram classificados como “Excelente”, com valores superiores a 96%. As diferentes lâminas aplicadas não influenciaram nos coeficientes. Entretanto, ao longo do tempo, as três fontes de água utilizadas ocasionaram diminuição do CUD, CUC e CUE, sendo que a maior redução foi encontrada nas parcelas que utilizaram efluente anaeróbio. Palavras-chave: água residuária, reúso, coeficiente de uniformidade, gotejador, tratamento anaeróbio e aeróbio. MACAN, N. P. F.; GOMES, T. M.; ROSSI, F.; TOMMASO, G.PERFORMANCE OF DRIP IRRIGATION SYSTEM USING DAIRY EFFLUENT TREATED BY BIOLOGICAL PROCESS 2 ABSTRACT The dairy industry produces effluents that can be reused on irrigation. However, the effect of these effluents on the irrigation systems is still little studied. Thus, the goals of this work were to characterize the dairy effluent treated by biological processes, classify it for its potential to cause emitter clogging, and evaluate the drip irrigation system uniformity by determination of emission uniformity coefficient (EUC), Christiansen coefficient (CUC), and Statistical uniformity coefficient (SUC). The experimental design was performed in randomized blocks, with a 3 x 3 factorial design, four replications, and coefficients evaluation over the time. The treatments consisted of three types of water: freshwater (AB), dairy effluent treated by anaerobic processes (EAN), and effluent treated by aerobic processes (EA) at three irrigation depths – 50% (W1), 100% (W2), and 150% (W3) – of the estimated table beet evapotranspiration. After 40 hours of irrigation, EUC, CUC e SUC were classified as excellent, with values greater than 96%. The different irrigation depths did not affect the uniformity coefficients. However, the use of the three water sources led to EUC, CUC and SUC reduction over time, and the largest reduction was found on plots that used anaerobic effluent. Keywords: agro-industry, uniformity coefficient, emitter, reuse, anaerobic and aerobic treatment.
