The Sorptive Behaviour of Steroid Oestrogens in Sewage Treatment Plants

 
Price: £12  

The ability of activated sludge particles to sorb steroid oestrogens was tested in the laboratory with fresh mixed liquor from an aeration tank and radio-labelled steroid oestrogen analogues. Most of the sorption was completed in the first minutes of the equilibrium. However, only ethinyloestradiol (EE2) was stable in the sewage matrix, the majority of oestradiol (E2) and oestriol (E3) were rapidly transformed. The main E2 by- product was another oestrogen, oestrone. With an ambient sludge concentration of 3.5 g/ L, only 13% of E3 (Kd 51), 30% of E2 (Kd 142) and 60% of EE2 (Kd 289) was removed by sorption.
