Research on Arsenic Release in Ground-Water-Based Distribution System

Abstract

The concentration of arsenic in effluent can meet standard requirements for drinking water after strengthening arsenic removal process, which is less than 10 μ g/L and stability in 5 ∼ 8 μ g/L. However, residual arsenic deliveries and releases in water distribution system by particle adsorption, migration, desorption and solution effect. Resulting in the water users' arsenic concentration increases. This research aims to study the arsenic enrichment characteristics, arsenic release rule in water distribution system and the relationship between arsenic release and the other water quality parameters through the network residual arsenic census and monitoring indexes of water quality.
