The impact generated by the indiscriminate disposal of heavy metals into the different bodies of water is not only environmental but also social due to the health effects it produces in several organisms, including ourselves. Therefore, treatment systems around the world are the subject of continuous research to find treatment systems that are economical, efficient, and easy to implement in the industries that generate these increasingly harmful impacts on society and the environment in general. One way to design and develop systems of water treatment is that which takes advantage of the waste generated, such as the waste from the E. crassipes plant. The conditions of this plant make it perfect due to its abundant biomass and important content of cellulose and hemicellulose. Nevertheless, in almost all the investigations that characterize the way in which the biomass of this plant adsorbs heavy metals, it does so under laboratory conditions, being very far from the reality of industrial discharges. The objective of this project is to design and develop a pilot-scale industrial wastewater treatment system with plant biomass and EDTA. Three pilot-scale systems were built with EDTA-modified biomass in different concentrations, giving the parameters of the design for the development of a system that can treat around 80 L of Chromium (VI) contaminated water. This treatment system with E. crassipes biomass and EDTA with proportions of 9:1 costs around USD 10, which is quite cheap compared to conventional ones.

“…Such rules set maximum permissible quantitative limits to avoid unpleasant or even dangerous effects. Thus, the prevention, development, or optimization of depollution techniques/technologies, and materials for advanced wastewater treatment is both a priority and a continuous challenge for specialists in the field of environmental sciences [1][2][3][4][5][6][7][8].…”

“…The advantages of these bioprocesses are that they use natural products, biodegradable, have low impact on the environment, and can remove a number of pollutants from various environmental matrices. The purpose of implementing such biotechnologies is to increase the efficiency of depollution processes based on the costbenefit principle, with respect to the constant reduction of energy costs and manual labor, reducing the volume of raw materials handled, eliminating any sources of pollution, and lack of secondary production of hazardous waste [1][2][3][4][5][6][7][8][9][10].…”

“…Biosorption using biomass (material of biological origin-microbial, vegetal, or animal cells containing in their structure different natural polymers such as polysaccharides and their derivates, proteins, lipids, etc.) as adsorptive materials, is a simple, useful, and effective treatment process [1][2][3][4][5][11][12][13][14][15].…”

“…The main advantage of bioprocesses (biotechnological, microbiological, biological), compared to certain physico-chemical treatments, is given by the fact that over 70% of the organic matter expressed by COD Cr can be converted into biosolids [6]. Thus, the depollution potential of different types of microorganisms opens directions to new emerging biotechnological processes to be further studied and transformed into practical and industrial solutions [1][2][3][4][5][6][7][8].…”

Polysaccharides as Support for Microbial Biomass-Based Adsorbents with Applications in Removal of Heavy Metals and Dyes

The use of biosorbents for the decontamination of industrial effluent (e.g., wastewater treatment) by retaining non-biodegradable pollutants (antibiotics, dyes, and heavy metals) has been investigated in order to develop inexpensive and effective techniques. The exacerbated water pollution crisis is a huge threat to the global economy, especially in association with the rapid development of industry; thus, the sustainable reuse of different treated water resources has become a worldwide necessity. This review investigates the use of different natural (living and non-living) microbial biomass types containing polysaccharides, proteins, and lipids (natural polymers) as biosorbents in free and immobilized forms. Microbial biomass immobilization performed by using polymeric support (i.e., polysaccharides) would ensure the production of efficient biosorbents, with good mechanical resistance and easy separation ability, utilized in different effluents’ depollution. Biomass-based biosorbents, due to their outstanding biosorption abilities and good efficiency for effluent treatment (concentrated or diluted solutions of residuals/contaminants), need to be used in industrial environmental applications, to improve environmental sustainability of the economic activities. This review presents the most recent advances related the main polymers such as polysaccharides and microbial cells used for biosorbents production; a detailed analysis of the biosorption capability of algal, bacterial and fungal biomass; as well as a series of specific applications for retaining metal ions and organic dyes. Even if biosorption offers many advantages, the complexity of operation increased by the presence of multiple pollutants in real wastewater combined with insufficient knowledge on desorption and regeneration capacity of biosorbents (mostly used in laboratory scale) requires more large-scale biosorption experiments in order to adequately choose a type of biomass but also a polymeric support for an efficient treatment process.
