Title

ELECTRICAL CONDUCTIVITY CHANGES IN DRAINAGE WATER SAMPLES EXTRACTED FROM DIFFERENT DEPTHS OF SOIL VIA IRRIGATION BY RAW AND TREATED DOMESTIC WASTEWATER OF EKBATAN COMPLEX

Pages

  1-12

Abstract

 Use of domestic wastewater and effluent from the treatment plants for IRRIGATION purposes, despite the existence of some inorganic and organic compounds in these waters and their effects on the physical and chemical properties of soil, needs special attention. According to the experts recommend for optimal use of these types of waters, local researches are required while considering regional conditions and quality of wastewater and effluents. Therefore, in order to evaluate the soil-plant complex effects as a biological filter on wastewater pollutants and to investigate their transport below the root zone as a result of IRRIGATION, a series of LYSIMETER studies were carried out in Tehran area. Drainage water samples obtained from depths of 20, 45 and 90 cm below soil surface, in the form of a two-year lysimetric research. A statistical "factorial experiments in the form of randomized complete design" (3 x 3 x 3) was used. Raw and treated domestic wastewater of Ekbatan housing complex and well water (control) was applied for IRRIGATION of raw edible vegetables such as parsley, carrot and tomato in a clay loam soil texture. To extract the drainage water samples from different depths, a series of thin perforated drains (8 mm diameter) were installed in 20 and 45 cm from soil surface. The results showed that maximum EC in drainage water samples were observed in well water, treated and RAW WASTEWATER irrigated LYSIMETERs respectively.Increasing the depth of sampling increased the EC quantity. The amount of EC in IRRIGATION waters were between 0.52 to 0.88 dS/m. For drainage water samples, it changed between 1.09 to 3.21 dS/m.
