Abstract While the water demands of Egypt can be met by the Nile’s water resources up to the century, the quality of the water is deteriorating rapidly due to the prevailing in appropriate waste water disposal practices. Many parts of the river are not suitable today for potable purposes due to pollution from both domestic and industrial . sources. This situation is expected to worsen with the growth in population accompanied by an increase in both industrial and agricultural production. Accordingly, priority for industrial pollution abatement within the Egyptian Environmental Action Plan (1992) has been designated to the industrial facilities along the Nile River . Oil and Soap industry is one of the industries which contributes greatly to the pollution load of the Nile River . The major hazards created by waste water from this industry are usually due to the presence of oil and grease in the effluent or process water. Such liquors often contain emulsion which aggravate the problem and cause immense difficulties for water treating authorities. Waste water from Salt and Soda company in Kafr E1-Zayat city, E1-Garbia Governorate, provides the material of this study. The plant produces oil (3rd grade) toilet and laundry soaps, pharmaceutical and industrial glycerin, silicate, and fodder. The waste constituents are mainly emulsified and floated oil, fatty acid,triglycerides and unsaponifeable matter of glycerol. Due to the chemicals used in the industrial processes, alkaline and acidic stream, soaps, dissolved salts, and suspended matters both organic and inorganic contaminants are also present. Waste water from this plant (31,000 m 3/d) discharges directly into the Nile River without . |
