In this study, influent, effluent, and sludge samples collected in selected wastewater treatment plants across the Durban metropolis were qualitatively and quantitatively investigated. It was revealed that the concentration of TCS ranged from 1.906 to 73.462 µg/L, from 1.732 to 6.980 µg/L, and from 0.138 to 2.455 µg/kg in influent, effluent, and sludge samples, respectively. The concentrations of TCC were found to be between 0.320 and 45.261 µg/L,

Results of a comprehensive study are reported for Darvill wastewater works (WWW) inflow in relation to biological nutrient removal process. The incoming and outgoing nutrient (ammonia and soluble reactive phosphorus (SRP)) concentrations were determined using standard testing methods. Calculations of biological nutrient removal (BNR) efficiencies were used to evaluate the effects of high inflow to the biological treatability of the activated sludge for the period 2016-2017. At inflows above design capacity the nutrient removal efficiency was found to be at an average of 40% and SRP removal efficiency being 64% for the period of the study. The nutrient removal efficiency had an inversely proportional relationship to the inflow into the plant with ammonia removal being mostly affected. When the plant is overloaded the BNR process is adversely affected.

The interactive effects of the operating parameters such as initial concentration, pH, adsorbent dosage and particle size were studied in a batch mode using central composite design. The characterizations of banana peels were done using point of zero charge (pHpzc), Fourier infrared transform (FTIR), scanning electron microscopy (SEM) and elemental composition (EDS). The point of zero charge of banana peels was determined to be 4.83. The FTIR, SEM and EDS showed the functional groups, surface morphology and elemental composition respectively before and after the adsorption process. The analysis of variance (ANOVA) showed a good fit of coefficient of determination (R2) for Cu and Pb being 0.998 and 0.988 respectively. The percentage removal of Cu and Pb increased with increasing adsorbent dosage, however, the bio-sorption capacity of Pb was greater than Cu. The optimized variable conditions for the bio-sorption of Cu and Pb using banana peel gave 99.79% and 88.94% removal for Pb and Cu respectively with initial concentration of 100 mg/L, pH 5, adsorbent dosage of 1 g and particle size of 75 μm. The above condition gave desirability of 0.959, which denotes that the optimum conditions are acceptable. The regression model and the agreement between the experimental and predicted values confirmed the validity of second-order polynomial equation for the bio-sorption of Cu and Pb using banana peels.

Environmental pollution of water bodies has become a great concern and threat to aquatic life as well as humans. Rapid industrialization and urbanization have led to the generation of toxic heavy metals which pollute the environment. Some of the industrial activities generating heavy metals include, metal plating and galvanizing, paint, thermal power plant, laundry processes, textile etc. Among various heavy metals generated from industrial effluents, lead (Pb) is one of the most toxic heavy metals commonly produced from metal plating and galvanising, paint, laundry process, mining, battery manufacturing and steel industries. Pb(II) is nonbiodegradable and the third regularly occurring toxic heavy metal in natural water bodies [1]. Lead (Pb) sticks indefinitely and remains in living tissues all through the food chain [2]. The effects of lead on humans include, damage to the nervous and reproductive systems, hypertension, mental retardation and abortion [3]. It also has great influence on children [4]. There are set rules and regulations to reduce the concentrations of

Hence, the removal of copper and lead ions from aqueous solution in single and binary systems using natural banana peels was investigated in a batch mode. Banana peels were characterised using FTIR, which gave the functional groups present. The spectra of banana peels loaded with Pb(II) had a higher percentage transmittance after adsorption. The point of zero charge pH pzc of banana peel was found to be 4.83 which makes it suitable for the adsorption of cations. Kinetic and isotherm studies were carried out at a pH of 5.5, concentration range of 10-100 mg/ L, and adsorbent dosage range of 0.1-1 g. A pseudo-second order model is fitted to the kinetic data suggesting chemical adsorption. The Langmuir isotherm performed well with the experimental data which means adsorption occurred as a monolayer on the surface of banana peels. The maximum adsorption capacity of Pb(II) for Langmuir isotherm was 66.67 mg/g. This indicated that in the single system banana peels have more affinity for Pb(II) than for Cu(II). At higher concentrations, the experimental data for the isotherm study showed the effect of a competitive phenomenon which affected only Cu(II) in the binary system. Natural banana peels are efficient agricultural waste materials that can be used for the treatment of wastewater contaminated with copper and lead ions. ABOUT THE AUTHOR This research is part of a larger project funded by the South African National Research Foundation (NRF) and has been running for the past 3 years. Research activities seek to find sustainable and eco-friendly solutions for the removal of heavy metals commonly found in South African waters and detrimental to life. To this end, a selected number of readily available and low-cost biowaste adsorbents such as sugarcane bagasse, orange peel, eggshell, mango peel, banana peel etc, are being explored. The study covers their characterization, batch experiments to study the adsorption mechanisms and kinetics, as well as pilot-scale column studies for scale-up and design of household filters and industrial-scale adsorption columns. The designed equipment should be capable of handling multi-solute systems.
