product of biological wastewater treatment process and contains various toxic substances …

Phosphorus is related to global human food security, and the global reserves of phosphate
rock are gradually depleting. Phosphorus recovery from wastewater is urgently needed, both …

Phosphorus is a nutrient that is essential to nature and human life and has attracted
attention because of its very limited reserves. Dwindling phosphorus reserves and soaring …

Phosphate tailings (PT) was used to reduce the release of heavy metals (HMs) during

The study was aimed at the reutilization of oyster shells (OS) as a calcium-based additive to
turn sewage sludge ash into phosphate fertilizer, employing the oxygen-enriched …

Pyrolysis of sewage sludge in the presence of humic acid (HA), CaO and kaolin was
investigated in order to examine the effects of organic and inorganic constituents on the …

Phosphorus (P) recovery from sewage sludge is one of the promising substitutes to the
phosphate ores to alleviate the shortage of P supply in the future. In this study, how …
