My story with sewage • began my story with sewage: after the expiration of pragmatic official academic domain for more than 35 years. • A contract with sewage body get rid security of 60 thousand cubic meters of water / day of wastewater pretreatment processor. • waterway was created twenty-kilometer length until the desired investment of those waters where the ground. • The establishment of an initial deposition basins each 1,000 meters basin size 5 × 2 × 10 meters so that we can no precipitation of solids in these basins. • has been exploited the topography of the place and the weather is warm and dry and the sun throughout the year to purify waste water, where the region of Upper Egypt (Aswan). • was created 12 sedimentation basin size 100 ×  100 ×, 6 meters. • have been prepared tree farm  jtrova plant for the production of bio-fuel 'and another for the production of wood from the trees of bologna. • Heavy metals can not be degraded through biological treatment, but can only be transformed from one organic compound or oxidation state to another. • Heavy metals can be transformed to become either less toxic, easily volatilized, more soluble in water. • bioremediation of heavy metals (can be achieved through the use of micro-organisms (Garbisu et al.) And water hyacinth plants - lotus flower), phytoextraction, phytostabilization, and phytovolatilization or a combination of all living organisms. • biological treatment indirectly also happens through bio precipitation of reducing bacteria sulfate (desulfuricans extracted sulfur) which converts sulfate to hydrogen sulfate, which reacts afterwards with heavy metals such as cadmium and zinc to form forms insoluble of these sulphides minerals. • The use of a combination kaoline and Al ninnvaat to remove some of the heavy metals (such as cadmium, mercury, lead, nitrates). • Mansay to achieve the reality is an investment that water and treated physically and chemically and biologically can extract all precious than metals, such as palladium, vanadium, copper, silver, platinum, lead through fluids working on extracting the dissolved or suspended solids within the materials that pass through it. . • are the same heavy metal that may pose harm to the ecological ecosystem, the same ones that can manufacture better Collectibles them to retain their human residue, and in this way guarantee that hitting two birds with one stone fertilizer free of heavy metals and precious metals are expensive other than to maintain the rights and the environment from pollution.
