Special Issue Information

Dear Colleagues,

Rapid development in the modern industry has resulted in an outstanding increment in wastewater generation at the production step. Globally, more than 80% of wastewater is discharged into the environment without treatment, with industry accounting for 28% of the total.

Industrial wastewater is the major contributor to contamination of aquatic and terrestrial ecosystems with toxic heavy metals such as arsenic, copper, chromium, cadmium, nickel, zinc, lead, manganese, iron, and mercury, whose hazardous bio-accumulative nature in biotic systems is attributed to their high solubility in aquatic environments. In addition, the wastewater from alloy, jewelry, electronics, battery, fuel cell, photovoltaic, petrochemical, ceramic, glass, and pharmaceutical industries also contains precious metals such as gold, silver, platinum, palladium, ruthenium, rhodium, iridium, and osmium. The massive discharge of industrial wastewater poses a severe threat to the ecological environment and loses a lot of metal resources. There has, therefore, always been a need for the removal or recovery of these toxic, non-biodegradable, and persistent heavy/precious metals from industrial wastewater. Nowadays, the recovery processes of metals from industrial wastewater streams have found to be significant attractions among various investigators worldwide. This Special Issue of Minerals is focused on the latest progress in recovering metals from industrial wastewater. Emphasis will be placed on recycling and reusing metals, as well as the sustainability and inexpensive production of clean, high-value products from industrial wastewater.

We look forward to receiving your contribution.

Phosphorus in water not only degrades water quality but also leads to a waste of resources. In this study, adsorption thermodynamics and kinetics were used to study the effect of sponge iron on phosphorus removal, and a filtration bed was used to simulate the phosphorus removal in polluted water. The results showed that the maximum theoretical adsorption capacity of the modified sponge iron was increased from 4.17 mg/g to 18.18 mg/g. After desorption with 18.18 mol/L of sodium hydroxide and reactivation with 6% (w%) sulfuric acid, the activation rate of modified sponge iron can reach 98%. In a continuous operation experiment run for approximately 200 days, the sponge iron phosphorus removal percolation bed showed a good phosphorus removal ability. Under the condition of TP = 10 mg/L, HRT = 1 H, the comprehensive phosphorus removal rate was 30–89%, and the accumulated phosphorus adsorption per unit volume was 6.95 kg/m3. Wastewater from the regeneration of the sponge iron base can be used to recover guano stone. The optimum conditions were pH = 10, n (Mg2+):n (PO43−):n (NH4+) = 1.3:1:1.1. Under the optimum conditions, the phosphorus recovery rate could reach 97.8%. The method provided in this study has theoretical and practical significance for the removal and recycling of phosphorus in polluted water. Full article
