Skeletal Structure-Based Conditioning for Improved Deep-Dewatering Efficiency of High-Salinity Food Waste Digestate

ACS ES&T Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

The solid–liquid separation of food waste anaerobic digestate residue (FD) is a crucial step in maximizing the efficiency and sustainability digestion processes. However, high salinity organic content FD significantly hinder conventional dewatering methods, making deep-dewatering particularly challenging. This study introduces composite conditioning strategy using basic aluminum chloride (BAC) complex quaternary ammonium salt surfactant (G agent) to enhance digestate's drainage performance by constructing skeletal structure within it. Experimental results showed that BAC+G reduced water from 90.69 ± 0.36 54.19 0.16%, achieving deep was unattainable with BAC or G agent alone. On macroscopic scale, treatment enhanced floc strength increased flocculated particle size 469.07 0.73 μm, approximately 18 times larger than untreated digestate, which mitigated clogging improved permeability coefficient 2.40 × 10–6 9.79 cm/s, ensuring smooth discharge. Microscopically, effective porosity 34.90%, tortuosity 1.45, overall (4.41), accelerating discharge further enhancing performance. Additionally, transformed particles hydrophobic, lowered interfacial free energy, formed stable structures, These findings demonstrate combining flocculation formation critical for high-salinity digestate. research provides promising approach improving management could have broader implications sustainable high-moisture streams.
