Study the effect of Industrial Dairy and Textile Waste Water on the Engineering and Geotechnical Properties of Fine-Grained Soil

Abstract

Understanding and prediction of engineering properties of fine-grained soils is of vital importance in Geotechnical Engineering practice. Fine-grained soil contamination occurs on a daily basis as a result of industrial development and pipeline or reservoir leaks.Due to the influence of the surrounding condition, substantial damage occurs in the foundations of buildings. The presence of industrial wastewater in the soil contributes to a change in its physical, chemical and mechanical properties, and then negatively affects the foundations of various facilities. . In addition to environmental issues such as groundwater contamination, the changing of the geotechnical qualities of polluted soil is a concern. As a result of the concentrations of pollutants resulting from the businesses such as Dairy products industry and spinning and weaving factories, are extremely high in developing countries. Disposal of untreated industrial waste water is a common problem in these countries. This paper describes an experimental investigation that was conducted to explore the effect of two types of industrial waste water the first type was dairy industrial waste water (DW) and the second was textile industrial waste water (TW) on the deformational behavior of fine-grained soil. Fine-grained soil used in this research was obtained in a natural phase from a soil excavation site for the construction of a residential building in the village of El-Kom Al-Ahmar, Shibin El-Qanater, Qualiobiyah governorate Fig.1, which was exposed to DW and TW at 2, 4, 6, 8, 12, and 16 months, Two remolded soil samples are generated for this investigation and combined with different types of industrial wastewater of constant moisture content (70%). The Atterberg limits, plasticity index, specific gravity, free swelling, optimal moisture content (OMC), and maximum dry density (γdmax) of each mixture were calculated after 0, 2, 4, 6, 8, 12, and 16 months of mixing soil with industrial waste water, the results revealed that as soil matures, the optimum moisture content (O.M.C) and free swelling values of the soil containing DW, TW rise after the addition of pollutants, whereas the maximum dry density, specific gravity (GS), and cohesiveness decrease.
