In this work, the potential application of TiO2-Fe-HNT photocatalyst-adsorbent composite in water treatment technologies was confirmed. The photocatalyst-adsorbent composite (TiO2-Fe-HNTs) was synthesized by the hydrothermal method and characterized by X-ray diffraction, thermogravimetric analysis, Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, and diffuse reflectance spectroscopy. The adsorption and photocatalysis mechanism by the TiO2-Fe-HNT composite were examined on methylene blue dye, rhodamine blue dye, naproxen sodium (pharmaceutical drug waste), and imidacloprid (pesticide). The TiO2-Fe-HNT composite was active in UV and visible regions of the electromagnetic spectrum. The adsorption and photocatalytic efficiency increased with increasing amount of HNTs. The photocatalyst-adsorbent composite exhibited excellent removal efficiency for pharmaceutical waste (naproxen sodium) and pesticides (imidacloprid). An adsorption equilibrium data fitted well with the pseudo-second-order kinetics for both methylene blue and rhodamine blue dyes with the intraparticle model describing its rate-controlling steps. The Langmuir and Freundlich isotherm models further described the adsorption of methylene blue and rhodamine blue molecules, respectively.

Abstract Coagulation-flocculation process is a widely used method in water treatment. In this study, mushroom waste was selected as natural coagulant to treat kaolin synthetic water via coagulation-flocculation process. Rotten mushroom and mushroom spent were evaluated separately. Functional group of mushroom wastes were analyzed using Fourier Transform Infrared Spectroscopy. Optimum dosage and pH of mushroom wastes and aluminium sulphate in kaolin synthetic water treatment were examined through jar testing. A comparative study on the effectiveness of mushroom wastes and aluminium sulphate in kaolin synthetic water treatment was evaluated in terms of turbidity removal percentage and sludge volume index. Results obtained from jar testing show rotten mushroom and mushroom spent achieved turbidity removal efficiency of 99.73% and 99.25% respectively at optimal pH of 4 and optimal dosage of 5 mg/L whereas 99.91% of turbidity was eliminated by alum under optimum condition of pH 9 and dosage 25 mg/L. Under optimized condition, sludge volume index value obtained by rotten mushroom, mushroom spent and alum were 37.38 mL/g, 40.34 mL/g and 51.58 mL/g respectively. Overall, the finding indicated that mushroom waste could be a potential alternative to chemical coagulant since they are environmentally friendly, effective in turbidity removal, producing less sludge and pH independent.
