Abstract

Water containing As waste is generated in many industrial processes, one of which is the fabrication of semiconductor devices from GaAs-related mate- rials. Industrial wastewater treatment plants are used to remove As and to permit the release of industrial water to municipal drains at As concentrations less than the legal maximum.
