Respirometric analysis of activated sludge models from palm oil mill effluent

In English

Författare

Summary, in English

Activated sludge models (ASMs) have been widely used as a basis for further model development in wastewater treatment processes. Values for parameters to be used are vital for the accuracy of the modeling approach. A continuous stirred tank reactor (CSTR), as open respirometer with continuous flow for 20 h is used in ASMs. The dissolved oxygen (DO) profile for 11 days was monitored. It was found the mass transfer coefficient K-La is 0.3 h(-1) during lag and start feed phase and 0.01 h(-1) during stop feed phase, while the heterotrophic yield coefficient Y-H is 0.44. Some of the chemical oxygen demand (COD) fractionations of palm oil mill effluent (POME) using respirometric test in ASM models are S-s 50 mg/L, S-1 16,600 mg/L, X-S 25,550 mg/L, and X-1 2,800 mg/L The comparison of experimental and ASM I from OUR concentration is found to fit well.
