Treatment of High Salinity Wastewater Rich in Nitrate and Phosphate Using Sequential Bioreactors System
S. B. Al-Shammari and A. Shahalam
Abstract—Kuwait has built and operated an advanced
wastewater treatment plant with present capacity of 500,000
m3/d. This plant providing treatment beyond tertiary utilizes
the process of ultra filtration (UF) and reverse osmosis (RO).
The reject water of this unit contains high concentration of total
nitrogen and total phosphate. Safe disposal of this water into the
environment or possible reuse needs substantial reduction of
these chemicals. In this study, a bench scale sequential
bioreactors system was investigated to treat a synthetic saline
wastewater rich in nitrogen and phosphorus compounds. The
system operated with an average hydraulic-detention time (HRT)
of 24 h whereas, Sludge age varied within the range of 13 to 16.5
d. The results show that the average removal efficiency of the
system for chemical oxygen demand (COD) was 81.3%. The
phosphate and nitrogen average removal were found to be
49.6% and 59.7% respectively.
Index Terms—Wastewater, treatment, saline, nitrate, phosphate.
