English Abstract
The recycled paper mill effluent (RPME) contains high concentrations of organic matter and therefore requires proper treatment prior to discharge.
There is a lack of experimental data available for the anaerobic digestion of RPME and its various important parameters such as temperature effect.
Therefore, the anaerobic digestion of RPME was carried out in modified anaerobic inclining-baffled reactor (MAI-BR) under low mesophilic (29 °C), mesophilic (37 °C) and thermophilic (55 °C) conditions.
The MAI-BR was continuously operated with COD of 2500 mg / L and HRT of 2 days, giving an OLR of 1.25 g COD / L.
day.
Experimental results showed that total COD removals in low mesophilic and mesophilic conditions were up to 95 % ; and the methane yields were 0.1 15 and 0.192 L CH4 / g COD, respectively.
Subsequently, when the temperature was increased to 55 °C, the COD removal in thermophilic condition was decreased to 76 %.
This is might be because of organic contents in RPME become highly soluble in thermophilic temperature.
However, the methane yield was 0.27 L CH4 / g COD which is much higher than that in the mesophilic conditions.
Hence, the RPME has been successfully treated over a wide range of temperatures.
