For evaluating the amelioration effect, organic carbon content and humus composition in soda saline-alkaline soil were investigated with …
Water Treatment: Aluminum sulfate is widely used in water treatment plants to clarify drinking water and wastewater.It helps in the coagulation and flocculation processes to remove impurities. Paper Manufacturing: In the paper industry, aluminum sulfate is used to size paper, improving its quality and making it more water-resistant.; Textile Industry: It is used in the dyeing and …
Aluminum sulfate [Al 2 (SO 4) 3 ·14H 2 O] applications to poultry litter can greatly reduce P concentrations in runoff from fields fertilized with poultry litter, as well as decrease NH 3 volatilization. The objective of this study was to evaluate metal runoff from plots fertilized with varying rates of alum-treated and untreated (normal) poultry litter.
Sustainable water and effluent treatments are essential tools for reducing the environmental impact of industrial activities. The partial or complete replacement of chemical coagulants, such as aluminum sulfate, with bio-based coagulants can reduce the environmental footprint of water and effluent treatment due to greater biodegradability and …
