BOD5 Estimation by Using UV Absorption and COD for Rapid Industrial Effluent Monitoring

  • Panalee Chevakidagarn
Article

Abstract

The study dealt with the method to predict the BOD5 in effluent from industrial wastewater by using the UV absorption from two wavelengths, 260 and 550 nm. The interference from suspended solids was reduced. In the same time, COD was used as the secure value to calculate BOD5. From the representative wastewater treatment plants, the estimated effluent BOD5 of wastewater from the Para rubber industry showed an average error at ±2.97 mg/l. While it was at ±3.31 mg/l, for frozen seafood industry. The simple mathematic equations in this study gave the assuring method for BOD5 estimation without time consuming.
