Resumen
Las aguas superficiales contienen, generalmente, partículas coloidales responsables de la turbidez, afectando su apariencia y causando efectos adversos en el tratamiento de aguas residuales ya que dificulta la eliminación o inactivación de organismos patógenos, siendo fuente de bacterias y virus. En este trabajo se analizó la eficiencia de biopolímeros naturales, como lo son el quitosano de camarón y cangrejo, mediante los procesos de desproteinización, desmineralización y desacetilación, además se realizó una comparación entre ambos para conocer cuál de los dos funciona mejor como coagulante – floculante en la remoción de turbidez. Los resultados demostraron que los dos tratamientos con quitosano ensayados en este estudio alcanzaron a reducir el 82,69% (Camarón) y 80,90% (Cangrejo) de la turbidez del agua. Siendo el quitosano de camarón más efectivo en la disminución de turbidez (Dosis de 0.5 gramos por cada 500 ml de agua), SDT y salinidad (Dosis de 1 gramo por cada 500 ml de agua, en ambos casos).
Surface waters generally contain colloidal particles responsible for turbidity, affecting the appearance and causing adverse effects in wastewater treatment. This makes it difficult to eliminate or inactivate pathogenic organisms as a source of bacteria and viruses. In this work, the efficiency of natural biopolymers, such as shrimp and crab chitosan, was analyzed through the processes of deproteinization, demineralization, and deacetylation. In addition, a comparison was made between the two to find out which works better as a coagulant - flocculant in the removal of turbidity. The results showed that the two treatments with chitosan tested in this study managed to reduce the turbidity of the water to 82.69% (Shrimp) and 80.90% (Crab). Shrimp chitosan was the most effective in reducing turbidity (Dose of 0.5 grams per 500 ml of water), SDT, and salinity (Dose of 1 gram per 500 ml of water, in both cases).
