Profiling and monitoring of DOM in brewery wastewater and treated wastewater

Dissolved organic matter (DOM) in raw and treated wastewater from two breweries in Thailand was profiled and monitored for the purpose of water reclamation. The wastewater and the effluent from the use of an upflow anaerobic sludge blanket (UASB) and activated sludge (AS) were collected and analyzed...
