Objective:
To develop a composite structural filter and evaluate its performance on-site for removal of high level arsenic in drinking water.
Methods:
Composite filters were manufactured using iron loaded carbon powder and superfine PE resin as main components. Test water was prepared by spiking arsenic in raw drinking water. The filter application safety and removal effects on arsenic and other parameters were tested.
Results:
The composite structural filter made of iron loaded carbon powder and superfine PE resin in equal quantity was safe for drinking water treatment and reached a capacity of 2.56mgAs/g for water with arsenic concentration of 0.4mg/L, and improved water turbidity and chemical oxygen demand apparently.
Conclusion:
The composite filter manufactured using iron loaded carbon powder and superfine PE resin as main components was appropriate for removal of arsenic in rural drinking water with high level of arsenic.
