“…In general, this step is performed through a chemical or thermal process. There are several possibilities to carry out the first of these two regeneration options: ultrasonication in acetone [6] or in methanol, followed by several washes in deionized water [7]; immersion in ethanol [8], also combined with water [9]; and by using mixtures that include acid/basic solutions [10][11][12][13][14][15]. Thermal evaporation is generally carried out at 100 • C [16,17].…”

The main techniques used for organic pollutant removal from water are adsorption, reductive and oxidative processes, phytoremediation, bioremediation, separation by membranes and liquid–liquid extraction. In this review, strengths and weaknesses of the different purification techniques are discussed, with particular attention to the newest results published in the scientific literature. This study highlighted that adsorption is the most frequently used method for water purification, since it can balance high organic pollutants removal efficiency, it has the possibility to treat a large quantity of water in semi-continuous way and has acceptable costs.

“…As shown in Table 3, most of the studies have focused their efforts on modifying BC with incorporation of other active materials, with the purpose to enhance its properties [22,46,104,[106][107][108][109][110][111][112]. The results of a recent study, performed on a BC membrane capable of acting both as a contaminant adsorbent and an antimicrobial agent, have indicated a unique and innovative way to remove viable bacterial cells from water [112].…”

“…The results of a recent study, performed on a BC membrane capable of acting both as a contaminant adsorbent and an antimicrobial agent, have indicated a unique and innovative way to remove viable bacterial cells from water [112]. Such modifications, among which it is worth mentioning amination, addition of aerogels, silica, chitosan and phosphate functional groups [104,[106][107][108][109], are studied according to the specific characteristics of the desired treatment [46,111].…”

Biocellulose for Treatment of Wastewaters Generated by Energy Consuming Industries: A Review

et al. 2021

View full text Add to dashboard Cite

Water and energy are two of the most important resources used by humanity. Discharging highly polluting wastewater without prior treatment is known to adversely affect water potability, agriculture, aquatic life and even society. One of the greatest threats to water sources are contaminated effluents, which can be of residential or industrial origin and whose disposal in nature must comply with specific laws aimed at reducing their environmental impact. As the oil industry is closely related to energy consumption, it is among the sectors most responsible for global pollution. The damage caused by this industrial sector is present in all countries, whose legislations require companies to carry out wastewater treatment before disposal or recycling in their production process. Bacterial cellulose membranes have been shown to be efficient as filters for the removal of various contaminants, including biological and chemical agents or heavy metals. Therefore, their use could make an important contribution to bio-based technological development in the circular economy. Moreover, they can be used to produce new materials for industry, taking into consideration current environmental preservation policies aimed at a more efficient use of energy. This review aims to compare and describe the applications of cellulose membranes in the treatment of these effluents.

“…e use of cyclic oligosaccharides, such as cyclodextrins, is extended due to its excellent properties associated with its ability for preparing of supramolecular structures. As result, a large number of publications are produced each year where cyclodextrin is involved [31,40,41]. ere are three kinds of cyclodextrins, which are known as α-cyclodextrin, β-cyclodextrin, and c-cyclodextrin, according to its generation.…”

The industry is looking for new materials which can respond to specific applications that exclusively advance materials can provide. In this context, nanoparticles and nanocomposites opened an interesting method for designing specific properties which can be modulated according to the requirements. The preparation of biomolecules supported trimetallic nanoparticles and some other derives is a good example of the complex systems that can be designed for getting exclusive properties. This study is based on the preparation of new cyclodextrin supported Fe/La/Zn trimetallic nanocomposite by the microemulsion technique. Photocatalytic degradation of amoxicillin was performed using cyclodextrin-Fe/La/Zn. 78% of amoxicillin photodegradation along 4 hours of photoirradiation was achieved. Finally, the catalytic nature of new material was explored for oxidation and esterification reactions. The present study revealed that this advanced multifunctional nanomaterial can be successfully employed for environmental remediation and catalytic activities.
