Abstract

Extraction and Use of Plant Biopolymers for Water Treatment

Highlights

  • Conventional water treatment processes include coagulation and flocculation, especially that which is chemically assisted, for both drinking water and wastewater

  • Weighing of the material of interest: The material obtained from the plants Melocactus sp., Opuntia dillenii, Stenocereus griseus, Cereus forbesii, Aloe arborescens, and Aloe vera is weighed to have a reference of its performance in relation to weight to weight, with respect to its use

  • After obtaining the biopolymers of the plants Melocactus sp., Opuntia dillenii, Stenocereus griseus, Cereus forbesii, Aloe arborescens, and Aloe vera, the preparation of the solutions is carried out to realize the tests of jars, which prove the action of coagulant and flocculant

Summary

Introduction

Conventional water treatment processes include coagulation and flocculation, especially that which is chemically assisted, for both drinking water and wastewater. These disposal problems of the sludge, which generally has a high concentration of organic matter, generate environmental impacts when they are discharged into soils or bodies of water, changing the natural microbiota and affecting the species that have contact with high concentrations of aluminum and iron To overcome this difficulty, different products of vegetable origin have been studied, which have properties similar to those of aluminum or iron compounds, generate coagulation and flocculation, but with organic compounds, are part of the natural components of plants come, as is the case of Melocactus sp., Opuntia dillenii, Stenocereus griseus, Cereus forbesii, Aloe arborescens, Aloe vera, and Kabuli chickpea (Cicer arietinum L.). To have a better selection, we reviewed the massive presence of these plants and that they were not part of the list of plants in danger of extinction, to be able to access their manipulation
