APPLICATION OF NANO-BANANA PEEL BIO-COAGULANT FOR THE TREATMENT OF TURBID AND RIVER WATER

Abstract

Application of Nano-Banana Peel Bio-Coagulant for the Treatment of Turbid and River Water ABSTRACT: As the world population increased the consumption of water and water treatment becomes critical. So, this research investigates the use of banana peel waste as a natural coagulant, eco-friendly modification of coagulation, synthetic water turbidity reduction, and river water purification. In this case, the typical particle size of the banana peel powder were 978 ± 37 nm, and modified powder were 571 ± 41 nm. The effectiveness of the coagulation was examined at various pH values, dosages, sedimentation periods, and NaCl concentrations. Up to 90% turbidity removal with 0.4 g/L of modified banana peel was found. While the coagulation performance was somewhat improved at concentrations of less than 0.4 g/L of NaCl, the activity was reduced, even in the modified powder, at higher concentrations. Banana peel powder significantly reduced watercolor, total dissolved and suspended solids, and chemical and biochemical oxygen demand in river water but only reduced turbidity by 75% and 83%, respectively, for non-modified and modified powders. The coagulation process was investigated and confirmed using SEM and FT-IR spectroscopy. Banana peel powder modified in this environmen¬tally friendly way has a lot of potential as a cheap and accessible bio-coagulant and can likely help to decrease wastages.

Description:DESCRIPTIONS:
Booming population, water consumption and availability are dramatically increased globally. Large amount of particles and dissolved contaminants makes sources of water unsuitable for daily need, particularly in tropical nations. The contaminations, which contain organic and inorganic minerals and chemical, affect the physical, chemi¬cal, and biological properties of water. Therefore, surface water goes through many stages of treatment and purification, obviously, it depends on the quality of water and prior to consumption. The use of coagulants to remove the impurities like color and turbidity from water which is finally settle at the bottom of the vessel and be
removed, is one of the water treatment methods that relies on coagulation. Several chemical (non-plant) based coagulants such as, iron oxides salts, in addition to various polymer nano com¬posites, have been evidenced in water treatment applications. The most popular metal saltwater treatment coagulants are those based on aluminum (sulfates of aluminum and chloride) and ferric (sulfate of ferrous and ferric chloride). Ferric chloride and aluminum sulfates are the most common coagulants used for treatment of waste water with excellent performance. On other hand the chemical coagu¬lants are dramatically change the pH level and reduced to a level closely to acid. Ferric chloride and aluminium sulphate are the most widely used metal-based coagulants that are characterized by their excellent performance in wastewater treatment; however, their use has the limitation of reducing the water pH to become close to acidic. In addition, they have been reported to cause some health issues to humans after the consumption of water, such as presenile dementia and Alzheimer's disease. Results are proved that poly¬aluminum chloride is the effective coagulant for removal of dissolved humic acid from water. Both polyaluminum chloride (PACl) and polyaluminum ferric chloride (PAFCl) have an appropriate capability to remove humic acid from surface water; however, PAFCl shown superior perfor¬mance in the treatment of aluminium residuals. The metal salt coagulant agents have the main drawback while treating the water that produce high amount of sludge and it is costly. Consequently, the organic base coagulants are the appropriate and better substitutions for any of these chemicals. Water treatment applications have utilized a variety of organic coagulants, such as Moringa oleifera, Cas¬sia alata and Cicer arietinum. These substances arecontaining multiple potent proteins that in charge of peels, while the processes coagulationcauses suspended particles from water chemically destabilize into larger agglomerates.The main advantages of natural coagulants have been studied, natural coagulants are safe for human health and the sludge generatedin treating water is often biode¬gradable, free from toxin, locally available, and economical. Applications for water purification have use extensive synthetic materials, such as cationic polymers, nano particles of titania, and nano particles of manganese ferrite. However, some of the natural coagulants are more expensive andnot vastly available it may limit their use. A Moringa oleifera seeds as a natural coagulant provides a better efficiency of turbidity but also noticeable color removal from sewage. Papaya seed for the same objective and has a direct link between the effectiveness of removal and coagulant dosage.The seeds from plants may not be readily available as large and might be used for other plant based things instead. In this investigation, it used a natural coagulant byproduct from banana peel. The banana tree has been claimed to produce from three to twenty fruits in a cluster only once a life span, and once the fruit has been consumed, various parts of the banana tree are not utilized, such as banana peels as well as stems, which are thus considered as waste. This organic com-ponents having low molecular weight, contains significant amounts of cellulose, lignin, pectin substances, pigments, chlorophyll, and other valuable organic substance.In every year, million tons of banana peels are thrown after consumption. The second most extensively grown fruit in south India is banana, which may be eaten either ripe or unripe. Unripe bananas are used to make chips, whereas ripe bananas are utilized to prepare fried bananas in the area. Huge volumes of bananas are used by chip and juice manu¬facturers each year, and producea lots of leftover banana peel. Approximately 30 to 40% of total weight of banana covered by peels, which typically disposed of in open space and leads to environmental issues. Recent studies revealed that banana peels are mostly composed of a number of bio¬polymers such as pectin, cellulose, lignin, and hemicellu-lose, as well as hydroxyl and carboxyl functional groups chemical compounds.These compoundsof banana peels contribute to completing, coordinating, chelating, hydrogen bonding, and/or other processes. As a result, these functional group components in banana peels are most suitable natural coagulant for applications involving water treatment. Banana peels have already been subjected to numerous attempts to improve coagulation performance, either with some other flocculants or by chemical alterations to the fruit peel. Chemical treatment could exacerbate existing problems by causing chemical leaching in treated water. Therefore, this study improved the efficiency of the banana peel as a coagulant by using an easy and inexpen¬sive preparation approach. This method involves micro¬wave radiation treatment followed by grinding operations in numerous times to alter the particle surface and reduce the particle size. Their findings supported and suggest that no need of any chemical reaction process to enhance the coagulation effectiveness of the natural coagulant. Banana peels with and without modifications were tested at various doses, pH levels, sedimentation rates, and NaCl concentra¬tions. By contrasting the impact of banana peel particle size and banana peel solution in a turbid water treatment, the inside function of banana peel powder coagulation was also examined. The use of plant waste has always been an excellent objec-tive of various researchers to ensure the use of sustainable natural materials and minimize different syntactic sub¬stances. This experiment confirms the effective efficiency of waste banana peel in the application of water treatment process.
