After full operation of secondary treatment at the East and West treatment plants, the future production of sludge from these plants and from Amriya and Agamy secondary treatment plants in addition to the rest 14 secondary treatment plants all around Alexandria is expected to exceed than 1200 m3/d by 2015 thus the capacity if the sludge disposal site should exceed. Therefore, the future sewage sludge management represents a critical environmental issue in Alexandria, this management includes sludge dewatering, handling, transportation cost to the disposal sites and the final product marketing.

As the capacity of Alexandria sludge disposal system will be limited by the increase in sludge production and the current management system, there is an immediate need to investigate ways to establish a future management system and to demonstrate successful operations at higher sludge producing rates.

Currently, Site 9N the sole disposal site in Alexandria include a composting plant established when the site was initially developed as a dedicated disposal area for sludge. Consequently, land spreading of the sludge on the dedicated disposal area has ceased and all of the current production of raw sludge is now being composted using the turned windrow technique.

The present study aims to evaluate the current efficiency of the sludge management system and adopt a future vision for the Alexandria sludge system and recommend modifications to protect public health and environment.

ABSTRACT After full operation of secondary treatment at the East and West treatment plants, the future production of sludge from these plants and from Amriya and Agamy secondary treatment plants in addition to the rest 14 secondary treatment plants all around Alexandria is expected to exceed than 1200 m3/d by 2015 thus the capacity of the sludge disposal site should exceed. Therefore, the future sewage sludge management represents a critical environmental issue in Alexandria, this management includes sludge dewatering, handling, transportation cost to the disposal sites and the final product marketing. As the capacity of Alexandria sludge disposal system will be limited by the increase in sludge production and the current management system, there is an immediate need to investigate ways to establish a future management system and to demonstrate successful operations at higher sludge producing rates. Currently, Site 9N the sole disposal site in Alexandria include a composting plant established when the site was initially developed as a dedicated disposal area for sludge.

Type it in or copy and paste from your Word document or other source. Click once on the dashed border to highlight then drag the bottom edge up to fit. Or change the font size to fill the box.

Or ‘No Line’ to remove the border altogether. The various elements and text boxes included in this template are examples of what we commonly see on posters of this kind. They are simply placeholders and you should feel free to add, delete, re-arrange, re-name, or re-size as best suits your needs. RESULTS DISCUSSION Genigraphics has provided this template to assist in preparation of a medical or scientific research poster. The dimensions are set to 24” high by 48” wide but prints can also be scaled up proportionally as large as 48” high by 96” wide. When you order your print we will know to scale the original file to the size you specify. Click here to insert your Discussion text.

Choose Genigraphics to print your poster and we will perform a free design review and advise you if we see anything that may be a concern for printing. We print directly from PowerPoint so your poster will look just like it does on screen. Other printing outlets (Kinko’s, for example) convert your file to another format prior to printing. This can result in elements shifting, loss of effects, or altered colors. By printing from the same version of PowerPoint that your file was created in, Genigraphics gives you the most accurate reproduction available.
