Comprehensive Review of Modification, Optimisation, and Characterisation Methods Applied to Plant-Based Natural Coagulants (PBNCs) for Water and Wastewater Treatment

Ibrahim Muntaqa Tijjani Usman et al.

Summary: This review investigates the modification, optimisation, and characterisation of plant-based natural coagulants applied to water treatment. Modification through microwave-assisted grafting copolymerisation is the preferred approach. Optimisation using response surface methodology is practical. Different techniques are used to determine the physicochemical properties of plant-based natural coagulants.

High surface area acid-treated biochar from pomegranate husk for 2,4-dichlorophenol adsorption from aqueous solution

Ensiyeh Taheri et al.

Summary: In this study, activated biochar was fabricated from pomegranate husk using zinc chloride and acid treating. The APHBC exhibited well-developed pores and high surface area, which resulted in efficient adsorption of 2,4-dichlorophenol. The experimental results also showed that pH, contact time, and APHBC dose influenced the adsorption efficiency.

Landfill leachate wastewater treatment to facilitate resource recovery by a coagulation-flocculation process via hydrogen bond

Sze Yin Cheng et al.

Summary: The recent trend of recovering value-added products from wastewater requires more effective pre-treatment technology. It is crucial to optimize leachate treatment to facilitate downstream processing for energy production or value-added products, by using simple yet effective technology to remove pollutants with minimum chemical additives.

Application of UV/chlorine processes for the DR83:1 degradation from wastewater: Effect of coexisting anions

Nasim Rafiei et al.

Summary: The study found that the coexisting anions had an impact on the degradation performance of UV/chlorine processes for dye-containing wastewater. Increasing pH reduced the efficiency, while increasing chlorine dose improved removal efficiency. HCO3 and Br ions were found to be the main inhibitors and promoters, respectively.

Optimization studies for water defluoridation with two-stage coagulation processes using new industrial-based chemical coagulants

Hooi Ren Lim et al.

Summary: The study investigated the fluoride removal capability of a new industrial-based chemical coagulant (Formula A) in one- and two-stage coagulation treatments. The results demonstrated that the coagulant concentration significantly affected the removal efficiency, with better results achieved at higher concentrations and an initial pH of 12. By optimizing the response, the highest removal efficiency of 70.12% was achieved at specific conditions of concentration, reaction time, and pH.
