Biochar captures N & P in dairy wastewater

Biochar can be used to capture essential nutrients from dairy wastewater and improve soil physico-chemical properties

dairy wastewaterAbstract.

Biochar has emerged as a promising solution for the potential to clean wastewater and recapture excess nutrients. With the ability to adsorb significant amounts of ammonium and phosphate from dairy wastewater in just 24 hours, the enriched biochar can potentially be returned to the soil to improve soil fertility. The use of biochar in this manner could significantly reduce the release of excess nutrient elements from agricultural runoff and promote long-term carbon sequestration. Additionally, utilizing locally available excess biomass to produce biochar could further enhance the sustainability of the process. The potential to capture significant amounts of ammonium and phosphate from dairy waste using biochar suggests a feasible strategy for clean wastewater, with the added benefit of disposing of excess biomass.

Biochar captures N & P in dairy wastewater — 1 Comment

  1. Sorry, I just noticed that I’ve posted on this paper already. But with N pollution issues bubbling in NZ water-table, it won’t hurt to recirculate. Interesting also, regarding P capture. Expert advise is that biochar is not so effective of P retention. This study points to a counter view? I guess it could be about finding the best biochar (biomass and process conditions) for P capture or post-production methods to modify the biochar.
