Title

Characterization of an Industrial Sewage Sludge and Its Evaluation for Land Application

Pages

  27-34

Abstract

 Background: Sewage treatment leads to the production of large amount of sludge, containing organic matter and nutrients and considering requirements for recycling could be used as fertilizer. The sludge may also contain various pollutants that pose serious harm to human health and the environment. This study aimed at characterizing the Industrial Sewage Sludge and evaluating its capability as fertilizer with no or a minor pretreatment. Methods: The sludge’ s organic matter and nutrient contents, Heavy Metals, organic and microbial contaminants were determined and compared to literature data and international guidelines. Results: The organic matter, nutrients, phosphorous, and exchangeable potassium contents of the sludge samples were signi􀏐 icantly high as follows: 33. 6 ± 2. 85 %, 6. 29 ± 0. 16 %, 1. 41± 0. 01 % and 1. 236 g/kg, respectively. The concentration of Heavy Metals was 94. 3 ± 59. 5 mg/kg. The concentration of Heavy Metals, organic contaminants, such as PCBs, BTEX, and PAHs, and microbial contents (coliforms & E. coli) were lower than those reported by other studies. Toluene concentration was high. Conclusions: All characteristics of the sludge samples, except for the toluene and microbial contaminations, were acceptable for its use as land fertilizer. Both toluene and microbial contaminants can be removed, using thermal conditioning as a pretreatment.
