Treatment of High Salinity Wastewater Using an Intermittently Aerated Membrane Bioreactor

Article Preview

Abstract:

In this study, high salinity wastewater was treated by an intermittently aerated membrane bioreactor (IAMBR) and the salinity loadings were set at 35g/L. The activated sludge was inoculated from the municipal wastewater treatment plant. The influent salinity level gradually increased from 0 to 35 g/L with every 5 g/L. With the salt concentration increased to 35 g/L, the performance of IAMBR was significantly affected by higher salinity. The removal efficiencies of the total organic carbon (TOC), ammonia nitrogen (NH4+-N) and total nitrogen (TN) were about 83%, 70% and 51%, respectively. It is indicated that the domestication of activated sludge from municipal wastewater treatment cannot obtain a better performance at high salinity.
