English Abstract
Wastewater treatment plant at Gaza and its infiltration basins are considered the primary sources of pollution for the ground water and sea water.
The historical records of Gaza Wastewater Treatment Plant from January 2000 to October 2004 were collected and evaluated to assess the system performance in term of removal efficiency for the Bio- Filter-Aerated Lagoon combined system.
This study attempts to highlight the factors leading to the inadequate performance of GWWTP in removing organic matter, solids, nutrients and microorganisms.
The efficiency of the different stages of the treatment process and the overall plant performance has been demonstrated. Collection and analysis of available historical data revealed a constantly decreasing removal efficiency of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and fecal coli form (FC).
Analysis of data showed that the combined system removal reached 91 %,87 %,88 %,97.5 % and 21.5 % of the influent BOD5,COD,TSS,FC and TKN respectively with an effluent concentration of 35.2 mg / l,110 mg / l,53 mg / l,7.73E+6 and 69.2 mg / l.
The decrease in the removal efficiency of the pollutants appeared to be due to the increase in the hydraulic and organic load that exceeded treatment plant designed capacity, inaccurate design parameters and inadequate operation. Over hydraulic and organic loading, increasing values of TSS than normal values, inadequate design of the plant and inadequate plant management are the main factors behind the drop in the treatment system performance.
The study presents proposals like the construction of another anaerobic lagoon and a grit chamber and splitting the flow equally between the trickling filters and the aeration lagoon along with the construction of another final settling tank which can be introduced as short, simple and economic solutions to overcome and improve the inefficient and poor treatment plant performance.
