“…O valor médio do pH do presente estudo foi semelhante a média de 7,56 encontrada por Miranda et al (2016) A média de SST presente na água produzida tratada do presente trabalho foi superior a média de 10,6 mg L -1 apresentada por Dickhout et al (2017). Analisando o valor médio de SST observou-se que, apesar das coletas das amostras terem sido realizadas após o sistema de filtragem, o risco de obstrução de gotejadores foi classificado como moderado (50 mg L -1 < SST < 100 mg L -1 ) por Bucks, Nakayama e Gilbert (1979), indicando que a água produzida, apesar de diluída em água subterrânea, apresentava uma grande quantidade de sedimentos; divergindo do resultado encontrado por Vale et al (2020) que obtiveram baixo risco de obstrução para o atributo SST, pelo fato da geologia de Jucuri-RN ser diferente de Upanema-RN.…”

“…A diluição da água produzida em água subterrânea é uma alternativa que minimiza a obstrução de emissores não autocompensantes. No trabalho realizado por Vale et al (2020) constatou-se, mitigação do entupimento, nas diluições de 10% de água produzida em 90% de água subterrânea e de 20% de água produzida em 80% de água subterrânea. A alternativa da diluição em água produzida tratada está relacionada à possibilidade de minimização dos efeitos de redução da qualidade do solo e do desempenho agronômico das plantas, além dos efeitos adversos ao ambiente (MILLER et al, 2020).…”

O tratamento e a diluição da água produzida do petróleo são duas técnicas que possibilitam a redução do potencial poluidor deste resíduo, bem como do seu risco de obstrução de emissores, caso possa ser utilizado para fins de reuso agrícola restrito. Objetivou-se, com este trabalho, analisar o risco de obstrução de emissores, bem como a modificação da vazão de emissores aplicando diluição de água produzida tratada em água subterrânea na proporção 1:10. Utilizou-se o delineamento inteiramente casualizado e esquematizado com parcelas subdivididas, em três repetições; as parcelas continham três tipos de emissores não autocompensantes (E1 -Netafim Super Typhoon, E2 -Netafim Streamline e E3 -NaanDanJain TalDrip) e nas subparcelas os tempos de avaliação da vazão dos emissores (0, 20, 40, 60, 80, 100, 120, 140 e 160 h). A vazão dos emissores e os atributos físico-químicos e microbiológicos da diluição de água produzida tratada foram obtidos a cada 20 e 80 h, respectivamente, durante o período operacional total de 160 h. Os atributos pH, cálcio e sólidos dissolvidos totais representaram risco severo de entupimento de gotejadores com agentes químicos. A maior suscetibilidade ao entupimento foi verificada para o gotejador E2, devido, provavelmente, ao seu menor comprimento de labirinto aliado à formação de incrustação no gotejador. O gotejador E3 é o mais recomendado na operação com água produzida tratada diluída na proporção de 1:10.

“…3 shows the bench test. The three-labyrinth-type and non-self-compensating drippers were chosen for their lowest clogging rates, highly commercialized in Brazil as shown in Table 4 (adapted from Vale et al, 2020). Produced water was retrieved from a petroleum-producing company on the Potiguar Basin, close to Jucuri RN Brazil, rural area in the municipality of Mossoró, Brazil.…”

“…The ASAE EP 405 standard proposes the following classification for FCV values: less than 10%, good; between 10 and 20%, reasonable; and greater than 20%, unacceptable (Asabe, 2008). Dilution samples for each treatment were collected by the end of each evaluation for physical and chemical analyses as shown in Table 5 adapted from Vale et al (2020). Samples were sent to the Laboratory of Soil, Water and Plant Analyses (LASAP) of UFERSA: pH was determined by pH-meter; electric conductivity (EC) was determined by conductivity-meter; calcium (Ca 2+ ) and magnesium (Mg 2+ ) were determined by titrimetric method.…”

The liquid residue called "produced water" from the exploitation of oil in the ground and sea is generated in large volumes and has significant polluting potential. In the Brazilian semiarid region, this liquid can be applied to the agricultural lands, if properly treated and applied to the soil by dripping. It is an alternative that can mitigate water scarcity and impacts on the environment. However, the vulnerability of drippers to clogging is a problem and can be mitigated with the dilution technique. The flow rate changes of drippers for the application of dilutions of produced water treated (PW) with underground water (UW) was analyzed. The experiment was conducted in a completely randomized split-split-plot design with three replications. Plots consisted of treatments (D1: 100% of UW, D2: 90% of UW and 10% PW, D3: 80% of UW and 20% of PW, D4: 70% of UW and 30% of PW and D5: 60% of UW and 40% of PW). The split-plots consisted of types of drippers (G1: 1.6 L h -1 , G2: -1.6 L h -1 , G3: 1.7 L h -1 ) and split-split-plots consisted of evaluation times (0, 40, 80, 120 and 160 h). Flow rate (D) and flow rate coefficient of variation (FCV) were taken every 40 hours untill 160 h. The results showed that the G3 emitter was the most resistant to clogging. The dilutions D2 and D3 provided the lowest losses in hydraulic performance in the drip units. The highest rates of clogging occurred in the G2 emitter operating in the D5 dilution.

The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance of non-pressure compensating drippers operating with dilutions of aquaculture effluent in well water. The experiment was in a completely randomized design in a split-split-plot scheme with three replicates, with five dilutions in the plots (Dilution 1: 100% aquaculture effluent; Dilution 2: 75% aquaculture effluent + 25% well water; Dilution 3: 50% aquaculture effluent + 50% well water; Dilution 4: 25% aquaculture effluent + 75% well water; and Dilution 5: 100% well water), three emitters in the sub-plots (ST (1.6 L h-1), SL (1.6 L h-1) and NJ (1.7 L h-1)), and three operating times in the sub-subplots (0, 80 and 160 hours, in which 0 hours operating time means the start of evaluations). The statistical analyses performed were correlation matrix and canonical analysis. The canonical correlation analysis indicated that when the concentrations of attributes increase, the hydraulic performance of the drippers decreases. The interaction of this group of attributes indicates that the clogging of drippers operating with the five dilutions of aquaculture effluent in well water occurs by the combined action of physical, chemical, and biological agents. The ST dripper was the least sensitive to the group of quality attributes of the dilutions, whereas the most sensitive was the SL dripper.
