Application


  • The coagulation process for virus removal in turbid water: Explores the use of aluminum chloride in the coagulation process to remove both enveloped and non-enveloped viruses, including SARS-CoV-2 Omicron BA.2, from turbid water. This research is crucial for environmental lab technicians and researchers in academia focusing on water treatment and public health safety (Maneein S et al., 2024).

  • Enhancing pollutants removal in hospital wastewater: Compares PAC coagulation and bio-contact oxidation methods in wastewater treatment, underscoring the impact of outdated plants and the role of aluminum chloride in enhancing pollutant removal efficiency. This study is essential for environmental scientists and engineers tasked with upgrading and optimizing wastewater treatment processes (Kang Y et al., 2024).

  • Comparing the effects of Al-based coagulants in waste activated sludge anaerobic digestion: Analyzes methane yield, kinetics, and sludge implications when using aluminum-based coagulants, providing valuable insights for environmental engineers and material scientists interested in resource recovery and sustainable waste management (Pasciucco F et al., 2024).

Features and Benefits

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties. Aluminum nitride can be synthesized from the elemnts with AlCl3 added to help facilitate crystallization.

Caution

Caution when opening! Due to production the supernatant gas phase can contain small amounts of toxic phosgene.
