Abstract

PHTHALIC ACID is a toxic organic compound, which can enter the environment through various industries.Biological removal of this pollutant before WASTEWATER disposal therefore plays an important role for environmental protection and human health. Due to ability of SBR system to remove domestic and industrial WASTEWATER contaminants, this system has been studied.In this research, SBR system with two different hydraulic retention times (24hrs and 48hrs) was used for biological elimination of PHTHALIC ACID. In this study, the volume of the reactor was about 7liters and total COD feed was adjusted to 1000mg/l, by using Glucose.Concentrations of inlet PHTHALIC ACID were 10,20,35,50,75,100,150,200 and 500mg/l respectively. COD, BOD5 and PHTHALIC ACID concentrations (using HPLC-UV with wave length of 200nm) were measured in the effluent.Obtained results showed that in both the retention times,more than 95%PHTHALIC ACID was removed. However, removal of PHTHALIC ACID in the one using 48hrs-retention time is more than that of 24hrs retention time. If the concentration of inlet PHTHALIC ACID is less than 200mg/l, hydraulic retention time equal to 24hrs is recommended. For concentrations of PHTHALIC ACID more than 200mg/l, use of 48hrs retention time is suggested.According to this study, recommended allowable volumetric loading rates for 24hrs and 48hrs are 200g/m3.d and 500g/m3.d respectively. The concentration of PHTHALIC ACID in the sludge was 200mg/kg.
