Abstract

Post-Hydrothermal Liquefaction Wastewater (PHWW) has a very high concentration of ammonium (6200 ± 106 mg/L), which is an inhibitor for the traditional sewage treatment process. The major objectives of this study were to: (1) evaluate the capacity of ammonium adsorption from PHWW using two zeolites (natural clinoptilolite and activated clinoptilolite) as the absorbent; (2) investigate the effects of zeolite particle size (0.18∼0.90 mm) and dosage (0.1∼0.5 g/mL) on ammonium adsorption efficiency; (3) study the regeneration methods of the natural clinoptilolite. Results obtained from the experiments showed that the optimized particle size and dosage of the natural and the activated clinoptilolite were 0.18∼0.30 mm, and 0.5 g/mL, corresponding to a highest ammonium adsorption efficiency of 51 ± 2% and 79 ± 1%; the ammonium adsorption efficiency of zeolite was positively related to the dosage; the smaller the particle size, generally the higher the ammonium adsorption efficiency; in addition, the activated clinoptilolite had a stronger activity and a larger capacity of ammonium ion exchange; when the natural clinoptilolite was regenerated with 4 mol/L NaOH and 0.1 mol/L HCl, the former was better. Application of zeolite on ammonium-rich PHWW is an alternative solution for reducing the concentration of toxic ammonium for subsequent utilization of PHWW.
