Sorption Mechanisms

In the past decade, researchers have carried out a massive amount of research on the application of biochar for contaminants removal from aqueous solutions. As an emerging sorbent with great potential, biochar has shown significant advantages such as the broad sources of feedstocks, easy preparation process, and favorable surface and structural properties. This review provides an overview of recent advances in biochar application in water and wastewater treatment, including a brief discussion of the involved sorption mechanisms of contaminants removal, as well as the biochar modification methods. Furthermore, environmental concerns of biochar that need to be paid attention to and future research directions are put forward to promote the further application of biochar in practical water and wastewater treatment.

Ultraviolet disinfection is the most efficient mode in combination with other disinfection methods within multi-barrier approach for the water treatment. UV disinfection being effective against a wide range of pathogens including the chlorine-resistant (viruses and protozoa) significantly reduces chlorine byproducts. This paper presents a review of results of the implementation of multi-barrier lay-out with the application of UV disinfection at water and wastewater treatment plants of large cities: St. Petersburg and Nizhniy Novgorod.

Electro Coagulation

Chemical and electrocoagulation are widely used coagulation methods employed in water and wastewater treatment. Both coagulation processes are effective in removing a wide range of impurities which include dissolved organic matter in form of chemical and biological oxygen demand, pathogens, oils, and colloidal particles as well as heavy metals. The present review has revealed that the mode of action of both coagulation methods is based on charge neutralization and floc formation. The effectiveness of both coagulation techniques depend on factors such as pH, coagulation dose, coagulant type, current density, applied voltage, water and wastewater  type, type of electrode, as well as size and number of electrodes. The commonly used chemical coagulants are inorganic coagulants based on aluminum and iron salts. However, there have been considerable successes in the development of pre-hydrolyzed inorganic coagulants which have the added advantage over traditional inorganic coagulants in that they function well over a wide range of pH and water temperatures. Electrocoagulation has been proposed as an alternative method to chemical coagulation because it is environmental friendly and cheap to operate. Nonetheless, most researchers are of the opinion that there are still some uncertainties regarding the understanding of its optimal performance and design mechanism.

Heavy Metal Ions Removal

This review paper focuses on the use of recycled banana peels for wastewater treatment. In India, more than 57.6 million tonnes of banana waste peels were produced each year, majorly are used as adsorbents to remove contaminants and pollutants that exist in the wastewater like heavy ions, organic and inorganic pollutants. To date, the use of waste banana peels as adsorbents have obtained substantial attention and countless modification have been done in order to improve their adsorption characteristics. Based on literature survey regarding the abundance of waste banana peels around the world, they are conceived to have considerable absorbency with optimistic application toward pollutants. According to published articles from the past 20 years, the technique of adsorption was recognized as most exceptional and cost-saving methods of treating wastewater with adsorption rate up to 98% of heavy metal ions removal and up to 98.93% for organic and inorganic compounds removal. Adsorption is most frequently used to remove atoms, molecules or ions from drinking water preparation, groundwater or as tertiary cleaning such as purification of biological water and wastewater treatment. Adsorption occurs when molecules in a liquid attach to the surface of a solid substance. This review extends applicable literature on the application of waste banana peels and its properties as an adsorbent on removing various pollutants in the wastewater. Evidently, adsorbents derived from waste banana peels demonstrated remarkable effectiveness towards removing various pollutants where the adsorption rate increases as the adsorbent dosage increases. Results concerning waste banana peels as adsorbents from several published articles have been discussed elaborately along with the future research perspective on waste banana peels.
