Research Project Title: Sludge Treatment, and Reuse using the Pyrolysis Technology

Research Project Purpose: The wastewater treatment plants equipment concentrate impurities in wastewater into solid form and then separate these solid from liquid. Due to the increased environmental concern; there is a considerable pressure on the wastewater authorities for the safe treatment and disposal of sludge. It is very important to choose a suitable sludge treatment and disposal system, which is both economical and technically feasible. The essential step in wastewater treatment sludge processing is the decline in its moisture content. Being this step is not achieved, it would be troublesome and extensively unfeasible to deal with and treat the sludge. Therefore, development of a complete sludge process treatment train for a certain type of sludge needs a good knowledge of the suitable and available techniques for processing that type of sludge. In this research, a more advanced technology (sludge pyrolysis) will be utilized to treat sludge and to investigate its applicability to be used as a safe, sustainable, nutrient rich, affordable and effective fertilizer.

Expected Results: 

  • Treated sludge with a simple natural and economic process, the produced treated sludge will be suitable for different agricultural applications.
  • Producing an amount of fertilizers that will be sufficient to fertilize agricultural areas of more than 1,500,000 m2 annually (1500 dunums).
  • The possibility for farmers to supply their lands with organic fertilizer at low cost and reliably available will be enhanced.
  • A very competitive fertilizer will be produced, since its cost will be less than the cost of the local organic fertilizer and that of the imported fertilizer from Israel.
  • Local experience in sludge management, treatment and reuse will be developed and enhanced.
  • Providing an acceptable option, in terms of cost and applicability, for sludge management and treatment.
  • Protection of the soil and groundwater from possible pollution through leaching of sludge contaminants to the subsurface soli layers and the aquifer.
  • Lowering the farmers’ input expenses paid for commercial fertilizers through utilizing the treated sludge as an efficient fertilizer.
  • A safe and acceptable method for sludge disposal will be adopted.
