Untreated wastewater in East Nablus: characteristics and design for treatment

Abstract

Nablus suffers from an environmental issue and health disaster comprised of untreated wastewater, especially in the eastern parts which this WW gathering and charge in Sajour wadi to leak into groundwater. Analyzing and finding a solution is crucial in this phase, so WW sample got through different tests at An-Najah labs in the civil engineering department, with suspicious extreme levels of concentrations such as total Kjeldahl nitrogen (TKN) (134mg/l), while Biochemical oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels are (746, 1412 mg/l) consequently. These results had used as an input for software modeling and dynamic simulation (STOAT 5.0) until reaching the Palestinian standard of treated WW type (A) to use treated water in the irrigation while prohibiting pollutants from getting to aquifers.
