“…However, the use of synthetic coagulants is disadvantageous due to the residual aluminum content they produce, since although the CWs are capable of removing them from the water, they can accumulate in the sediments and/or the biota and can be deleterious in the medium/long-term. Therefore, natural organic coagulants should be seen as an attractive alternative to chemicals because of their abundant availability, low cost, non-toxicity, and multifunctionality (Tukki et al 2016 ; Rahmadyanti et al 2021 ). The way the pesticides are applied in the rice fields and surrounding crops of the CWs (tractor, bag spraying, helicopter) plays a determining role in their presence in the CWs waters.…”

“…Por esse motivo, alguns biopolímeros vêm sendo investigados mais intensamente, como é o caso da Moringa oleifera (FRANCO et al, 2017;OTHMANI et al, 2020). Isso acontece devido a sua disponibilidade, baixo custo, não toxicidade, baixa produção de lodo e comportamento multifuncional (BHUPTAWAT et al, 2007;NWAIWU & LINGMU, 2011;MADRONA et al, 2012;DANTAS et al, 2016;TUKKI et al, 2016;VALVERDE et al, 2018).…”

“…De acordo com Bergamasco et al (2018) e Silva et al (2020), a não alteração significativa do pH implica em redução de custos com a adição de produtos químicos para correção de pH, já que, ao contrário dos coagulantes inorgânicos, o processo de coagulação com biopolímeros não consume a alcalinidade do meio (STRÖHER et al, 2013). Em seus estudos, Othmani et al (2020) e Rocha et al (2020) encontraram que o tratamento à base de plantas, a exemplo da MO, não altera o pH do efluente tratado.Caracterização do lodoEm virtude da pequena produção de lodo durante o experimento, situação também relatada porBhuptawat et al (2007), Nwaiwu e Lingmu (2011),Madrona et al (2012),Dantas et al (2016),Tukki et al (2016) e Valverde et al (2018, foi possível mensurar duas amostras dos lodos (amostra "A" e "B") coletadas em períodos distintos e submetidas às análises de composição química. Os resultados quanto à presença de lipídio, proteína e amido seguem descritos na Tabela 1.As análises de composição mostraram a presença de lipídios e proteínas, enquanto para o amido houve ausência (Tabela 1), com pequenas variações entre as amostras dos testes, sendo, porém, estatisticamente iguais, segundo a inferência estatística (t Student com 95% de significância).…”

“…Water quality has significantly deteriorated and drinking water access has become one of the major problems faced due to rising populations and industrialization, especially in developing countries (Tukki et al, 2016). The World Health Organization (WHO) estimates that 1.8 billion people in the World still do not have access to drinking water and more than 800,000 people are estimated to die of diarrhea as a result of low-quality drinking water, sanitation and poor hand hygiene every year (WHO UNICEF, 2015).…”
