Aloe Vera waste for Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO) adsorption.

(Corresponding) Mazzeo L., Bavasso I., Di Palma L.
Topic: 
Wastewater treatment
Aloe Vera (Aloe barbadensis miller) waste obtained from a local cosmetic production factory was used as bio-adsorbent for the removal of three different dyes: Methylene Blue (MB), Rhodamine B (RB) and Methyl Orange (MO). The material was preliminary washed with water at room temperature. Batch...Read more

Linear Bivariate Expressions for Marine Benthic Macrophytes Ecological Status Description

(Corresponding) Tzouvaras N.
Topic: 
Marine environment and coastal management
Regarding ecological status assessment with marine benthic macrophytic indicators as per European Water Framework Directive (WFD), linear models are being reviewed (either starting from discontinuous forms or modifying quadratic and algebraic forms). Through use of simple concepts, model...Read more

An overview of pressure-driven membrane technologies for a sustainable recovery of volatile fatty acids (VFAs)

Pervez M., Mahboubi A., Hasan S., Cai Y., Zarra T., Belgiorno V., Taherzadeh M., (Corresponding) Naddeo V.
Topic: 
Food waste
Currently, petroleum-based volatile fatty acids (VFAs) sources are not acceptable towards sustainable development goals (SDG); therefore, biobased-derived VFAs are of interest. Anaerobic digestion has been identified as a useful technology for the production of biobased VFAs from organic waste...Read more
