English Abstract

The aim of this study is to evaluate the feasibility of using sewage sludge produced from Gaza wastewater treatment plant, as an agricultural fertilizer.

The sludge studied was collected from Gaza Wastewater Treatment plant (GWWTP), as the accumulated one stated in the collection lagoons for a period of time more than six months.

Before using, sludge was passed through several steps of processing, such as drying at sun light, cleaned off plant tissues and grinding to a proper size.

The physicochemical analysis results showed that the sludge can be a valuable resource if used as a fertilizer and soil conditioner and can supply all micro and macronutrients necessary for plant growth since the results of the nutrients showed that the average TKN concentration was 5440 mg/kg and NH4-N was 3594 mg/kg and NO3-N was 125 mg/kg, these values showed rich content of nitrogen, where they are considered as essential nutrients.

Potassium and Phosphorus are another essential nutrient with average value 525 and 213 mg/kg respectively.

The total concentration of Cr, Zn, Cu, Pb and Cd meet regional and international standards for agricultural use, and they were, 119, 1660, 245, 92 and 2 mg/kg respectively
