“…On average, the removal efficiency of turbidity was 50.2% with a standard deviation of 15.14%. This differs from the efficiencies found by Olivero et al (2014) and Miller et al (2008), who achieved reductions in turbidity between 83.66% and 92%-99%, respectively, using the nopal as a natural coagulant to clarify raw water; however, the methods used to extract the nopal mucilage were different from our study, and this most likely significantly affected the final result regarding effectiveness of the coagulant. Likewise, an investigation conducted by Mukhtar et al (2015) also achieved higher removals (i.e., up to a 91% reduction in turbidity) but other species of cactus were used, specifically Opuntia stricta, which would make it necessary to investigate the efficacies of other species of cactus native to Colombia, such as Melocactus curvispinus Pfeiffer subsp.…”

Aluminum sulfate is one of the most used chemical coagulants in the world, but research has shown that high concentrations of aluminum in the body are associated with neuropathological conditions. Because of this, different alternatives have been evaluated such as natural coagulants, which are considered safe for human health and contain fewer contaminants than chemicals due to their biodegradation properties. The main objective of this study was to evaluate the efficiency of mixing nopal mucilage and cassava starch for turbidity removal in water purification. In this paper, test jars and the treatment equipment (TA-scale FQ-005/PE manufactured by Generatoris SA de CV of Mexico) was applied in order to measure turbidity and pH parameters before and after the process of coagulation-flocculation, which was applied to water from the Magdalena River in Colombia. Samples from two sampling periods were assessed. One was evaluated during the rainy season and the other was evaluated without precipitation (drought) with initial turbidities of 316 NTU and 80 NTU, respectively. It was found that aluminum sulfate as a coagulant reference obtained better turbidity removal results (up to 99%) as compared to nopal (up to 60.4%), and nopal-starch combination of cassava (up to 67%), indicating that this mixture increases the effectiveness of natural coagulants used individually. Our results indicate that this should be considered as an alternative in the water purification process.

“…En el año 2014, se determinó que a una dosis de 40 mg/L la turbidez del agua del río Magdalena en el municipio de Magangué-Bolívar, es removida un 98,30% partiendo de una turbidez inicial de 174 UNT [25].…”

En esta investigación se analizó la eficiencia de la médula de banano como sustancia coagulante en la clarificación de aguas naturales y se comparó con el sulfato de aluminio. Se utilizó un diseño experimental factorial, siendo la dosis (10, 20, 40, 60, 80y 100 mg/L) y el tipo de coagulante (químico o natural) los factores. La turbidez del agua del río Magdalena se empleó como variable respuesta. El proceso de clarificación se realizó mediante la aplicación de la prueba de jarras usando muestras de agua del río en Barranquilla, departamento del Atlántico, Colombia. Se comprobó mediante el análisis estadístico ANOVA y la prueba de HSD (diferencia significativa) de Tukey, que el coagulante natural reduce la turbidez inicial del agua objeto de estudio (210 UNT) en un 67,57%. La médula de banano siendo un residuo agroindustrial es una opción viable y sustentable en la remoción parcial de la turbidez del agua del río Magdalena.

“…Some coagulants employed to remove impurities and colloidal particles from wastewater are ferric chlorides, aluminum sulfate, polyaluminum chloride, and calcium carbonate (Bergamasco et al, 2009). Nevertheless, there are some disadvantages related to the use of coagulants, such as cost, production of large volumes of sludge and pH modifications of the treated water (Olivero et al, 2014;Yin, 2010). Bergamasco et al, 2009).…”

Coagulants can be extracted from vegetal material and applied in the treatment of wastewater. These coagulants are derived from seeds, leaves, bark, roots and fruits. This study focuses on the use of the mucilaginous extract of Stenocereus griseus (known as Cardón Guajiro) for removal of biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total solids, turbidity and color in domestic wastewater from a pumping station in the city of Cartagena (Colombia). The optimal dose of S. griseus extract was determined by a pitcher test employing an E&Q F6-300 digital flocculator. All physicochemical tests were carried out following the specifications of the standard methods for wastewater (APHA). When 1400 mgL-1 of natural coagulants were used in the sewage treatment, the turbidity obtained was 29.57 TNU, representing removal of 67.24%, considering the initial turbidity. This parameter decreases until 68.61 PCU, for a 72.12% removal at the same coagulant dosage regarding the color. It must be noted that significant statistical differences were found between all tested doses of the coagulant. The mucilaginous extract of S. griseus exhibited useful properties in the primary treatment of domestic wastewater.
