Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Intensification of Activated Sludge Waste Water Treatment

Water Science and Technology, 1986
The efficiency of two possible intensification methods of activated sludge waste water treatment (pure oxygen activation and activated carbon addition) were compared. Experiments were carried out in laboratory scale equipment with variable reactor volume (maximum capacity 20,0 dm3, settling tank vol. 15 dm3).

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

International Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

Anaerobic Co-Digestion of Fats, Oils and Grease (FOG) with Waste Activated-Sludge

Chemical Engineering Transactions, 2012
Two mesophilic batch digestion runs were set-up in which a FOG is co-digested with waste activated sludge. FOG loadings range from 0 to 50 % of the VS. This co-digestion of FOG and activated sludge successfully increased the biogas production up to 400 %
