Reduction of Total Phenols, Total Phosphorus and Turbidity by Uncatalytic Oxidation Processes in Cheese Whey Wastewater

Autor: Ana R. Prazeres, Silvana Luz, Flávia Fernandes, Eliana Jerónimo

Publikováno v: Proceedings, Vol 38, Iss 1, p 16 (2020)

This study reports the first time that cheese whey wastewater has been treated by the hydrogen peroxide oxidation alone (uncatalytic reaction). This oxidation type was capable of eliminating the total phosphorus content in about 46−53%, regardless

Contamination reduction of real olive oil mill wastewater using innovative acid and basic chemical precipitation processes

Autor: Raquel Cristina Da Silva Guerreiro, Eliana Jerónimo, Ana R. Prazeres, Alexandra Afonso

Publikováno v: International Journal of Environmental Science and Technology. 18:799-808

Olive oil mill wastewater is a strong pollutant with low pH (4.63) and high salinity (2.70 dS m−1), organic matter (chemical oxygen demand (COD) = 7910 mg L−1), total phosphorus (1049.7 mg L−1), total phenols (540.4 mg L−1) and turbidity (280

Simple processes for contamination removal in cheesemaking wastewater: CaCO3, Mg(OH)2, FeSO4 and FeCl3

Autor: Silvana Luz, Ana R. Prazeres, Eliana Jerónimo, Flávia Fernandes

Publikováno v: Journal of Environmental Chemical Engineering. 8:104034

The treatment of cheesemaking wastewater by means of four processes (CaCO3, Mg(OH)2, FeSO4 and FeCl3) has been investigated in order to reduce the total phosphorus, turbidity, total phenols, chemical oxygen demand (COD) and absorbances. It has been d

Cheese manufacturing wastewater treatment by combined physicochemical processes for reuse and fertilizer production

Autor: Helena M. Pinheiro, Eliana Jerónimo, Ana R. Prazeres, Silvana Luz, Raquel Cristina Da Silva Guerreiro

Publikováno v: Journal of Environmental Management. 264:110470

Making cheese manufacturing environmentally sustainable is a major concern in the integrated management of this industrial sector. This concern is mainly due to the environmental impact of the discharge of its wastewaters, carrying heavy loads of sal
