[013] “Use of a biocoagulant produced from Opuntia robusta for the clarification of domestic wastewater”

Nowadays, aluminum sulfate is the most widely used coagulant for wastewater clarification. However, it is directly related to negative impacts on human health and the environment. One alternative to using this chemical compound is the production of biocoagulants. So, in this wok, the clarification efficiency of a biocoagulant obtained from Opuntia robusta in combination with aluminum sulfate was evaluated in domestic wastewater samples. An experimental design based on mixtures was developed. The numerical factor was the mass ratio of the coagulants to be used (Opuntia robusta and/or aluminum sulfate) in concentrations of 200 to 800 mg/L. The turbidity removal percentage was defined as the response. Ten experiments were performed in the jar test according to the experimental design. The physicochemical characteristics of the water (pH, temperature, conductivity, turbidity, and COD) were evaluated before and after the jar tests. The initial turbidity was 56.07 NTU, the results showed an optimal coagulant dose of 200 mg/L with a mass fraction of 0.3 of Opuntia robusta and 0.7 of aluminum sulfate, achieving a percentage of turbidity and COD removal of 67.63% and 72.66%, respectively. The use of the biocoagulant in the treatment does not significantly modify the water properties (pH, temperature, and conductivity). These results suggest using the biocoagulant obtained from Opuntia robusta in dual systems in the clarification of domestic wastewater.
