Abstract

Constructed wetland (CW) system is a very promising and attractive technique especially for developing countries. Proper design of such systems can help in the improving of the quality of the final effluent. In this work different CW inlet designs were studied for the treatment of wastewater. The detention time was kept constant at 2 days in the different units. The triangular inlet could affect the performance of the CW units as revealed by the obtained results. The organic loads as represented by COD and BOD were reduced by 12% and 36% for FWS and 9% and 21% for SSF with triangular inlet shape than the rectangular inlet shape units. The count of fecal coliform (FC), Fecal streptococci (FS), Pseudomonas aeruginosa (PS) were reduced by variable degrees while, Salmonellae not detected in the treated effluents.
