Nutrient recovery from wastewater not only reduces the nutrient load on water resources but
also alleviates the environmental problems in aquatic ecosystems, which is a solution to …

Fluidized bed crystallization granulation technology was first applied to water softening and
gradually achieved improved results from initial exploration to large-scale chemical plants. It …

The increasing global population, over the last few decades, brought about the rise in
synthetic fertiliser market prices along with explosive agricultural demand. Source …

Swine wastewater contains phosphorus, ammonia nitrogen, and heavy metals that affect the
struvite purity produced from the wastewater and increase the ecological hazards. In …

The integration of biological nitrogen (N) removal with struvite-type material recovery, which
contained phosphorus (P) and potassium (K), was proved to be technically feasible in pig …

This study investigated nutrient recovery by struvite precipitation from anaerobic digester
supernatant containing nitrogen and phosphorus at high concentrations using a fluidized …

Urine, traditionally regarded as liquid waste, contains valuable elements–nitrogen (N),
phosphorus (P), and potassium (K) which can be repurposed as crop fertilizers. Under the …

Residual oil containing platinum group metals (PGMs), which is under-researched, can
easily pose resource waste and environmental risks. PGMs feature as scarce strategic …

Phosphorus (P) and potassium (K) are the two main nutrients of plants. It is of great
significance to recover P and K from wastewater, which can reduce phosphate and potash …

Existing techniques to recover phosphorus as vivianite from urban sewage face difficulties in
separating the crystals from the sludge. The present study proposes a new process for the …
