Global deposits of concentrated phosphates, which are a necessary source for the
production of phosphate fertilizers, are limited. These reserves keep getting thinner, and …

Discharging of dewatered dry sludge into the environment can trigger irreversible
environmental damage. The treatment of dewatered dry sludge into a valuable biochar …

Large amounts of septic tank sludges from sanitation facilities are either landfilled or illegally
dumped into the natural environment, leading to environmental pollution and waste of …

This study evaluated the potential of biochar impregnated with Fe3+ or Ca2+, or mixed with
Polonite®, as a filter material for removal of phosphate (PO4-P) from wastewater in onsite …

A novel limestone-modified biochar derived from sewage sludge was prepared to reclaim
phosphorus (P) from aqueous solution, and the potential application of P-laden biochar as …

In order to reduce phosphorus (P) discharge into aqueous systems, wastewater treatment
plants usually precipitate sludge water with iron or aluminum salts and produce slow …

Aluminum ions extracted from water sludge and waste biomass (Korean pine residue) were
utilized to develop a biochar for phosphate removal. The biochar impregnated with the …

Increasing problems related to water eutrophication, commonly caused by the high
concentration of phosphorus (P), are stimulating studies aimed at an environmentally safe …

Phosphorus (P) recovery from wastewater using biochar is an alternative to P recycle and
reuse. However, the impregnation of cations for biochar production is needed to enhance P …

The demand to control eutrophication in water bodies and the risk of phosphorus scarcity
have prompted the search for treatment technologies for phosphorus recovery. In this study …
