This study experimentally investigates the reaction sensitivity and interactions of temperature, oxidation coefficient, time, and pressure in the SCWO of oily sludge. The results show that temperature has the strongest reaction sensitivity for treatment efficiency, while the effect of pressure can be neglected. Enhancing another operating parameter within any given range of one operating parameter will promote the reaction. Additionally, a dual-constraint reaction prediction model, coupling treatment efficiency with energy consumption, was developed.

Herein, the utility of a recently developed granular chitosan-Cu(II) biocomposite adsorbent (CP-Cu) for the adsorption of sulfate from environmental groundwater systems is reported. Several types of groundwater samples (Wells-1, -2, -3 and -4) were investigated for sulfate removal via a fixed-bed column, characterized by kinetic adsorption parameters in laboratory and groundwater samples. The lowest exhaustion time for CP-Cu was observed for Well 3, due to its high sulfate concentration of 6772 mg/L. In turn, the adsorption capacity under dynamic conditions for Well 3 was the highest (153 mg/g) compared to the other groundwater samples. Modeling of the experimental sulfate removal under dynamic conditions was achieved using the Thomas, Yoon-Nelson, and Adam-Bohart models. The best-fit results showed that the Thomas and Yoon-Nelson model described the breakthrough curves favourably, as compared with the Adam-Bohart model. The prediction of the sulfate adsorption capacities by the Thomas model are in close agreement with the experimental results.

We show that this equation, originally introduced in the 1960s, constitutes a separate kinetic model with no mathematical relationship to the PFO model.
