Abstract:

Pentavalent arsenate (As(V)) is a toxic chemical and the presence of As(V) in drinking water can lead to a number of diseases. Many treatment technologies have been developed and implemented to remove As from drinking water. However, the high treatment cost and complicated nature of As treatment systems present the main challenges in applying these technologies, especially at a decentralised scale and in rural or isolated areas. The main objective of this research is to develop novel and cost-effective methods that can be applied widely to remove As(V). Cost-effective adsorption based on novel adsorbents and electrocoagulation with solar energy were the main focus of this study. This study found that novel adsorbents developed from Vietnam manganese oxide ore and 𝘭𝘶𝘧𝘧𝘢 plant fibre are promising media for As(V) removal. They are cost-effective, locally available, and highly effective materials. They can also be safely disposed into the environment once the treatment process is completed. The novel electrocoagulation process using renewable energy is also an environmentally friendly and promising approach. The choice to apply these treatment methods depends on the field conditions, but generally, they could be carried out in the rural and isolated areas with poor infrastructure.
