Journal of Applied and Emerging Sciences Vol (11), Issue (1) [47] https://doi.org/10.36785/BUITEMS.JAES.413 Abstract-- Among various pollutants, wastewater consists of toxic or carcinogenic heavy metals such as lead (Pb), zinc (Zn), and copper (Cu). In this study, the contamination of heavy metals in residential (Domestic) and commercial (Car-wash centre) effluents from urban area of Quetta has been investigated using atomic absorption spectroscopy. The collected liquid effluent was passed through sorbents in vertical flow. The combined batch of Fly ash and Sawdust (adsorbents) showed high sorption capacity 0.0000424 mg·g -1 for lead (residential liquid waste) and 0.0000012 mg·g -1 for Cu (commercial liquid waste). The moderate partition coefficients were 0.001247 (Pb) and 0.000005 (Cu) mol·kg -1 ·Pa -1 for residential and commercial waste respectively. The highest removal efficiency of lead (99.763%) for residential effluent showed the breakthrough at 0.002. Thus, the sorbents have used significantly high removal efficiency for Pb, moderate for Zn, and low for Cu. The effluent passed from designed filter media may be greatly effective for partial domestic usage i.e., washing, cleaning and irrigation purpose Keywords-Lead; Zinc; Copper; domestic waste; Fly ash; Sawdust Date Received: 06-10-2020 Date Accepted: 26-10-2020 Date Published: 08-06-2021 I. INTRODUCTION he human activities around the globe have severally affected the quality and quantity of natural resources e.g., fresh water. Every community utilizes water and produces liquid waste also known as wastewater. Wastewater has a source from any combination of domestic industrial, commercial, agricultural, surface runoff, storm water, sewer inflow, and sewer infiltration [1]. Untreated wastewater when discharged to the environment can lead to the emission of anthropogenic gases. Wastewater consist of substantial amount of toxic heavy metals to which human are exposed through various paths [2]. According to the United Nation (UN) , it has been observed that a substantial increment ~ 50% area has been effected due to untreated wastewater in the last decade [3]. Globally ~80% of untreated wastewater were discharged into the environment replicated hazardous conditions [4]. According to United Nations (UN) statistical data, ~70 countries around the globe have non-functional wastewater treatment plan. On the other hand, the local entities consume crops planted on land that is irrigated using untreated wastewater. Five countries i.e., China, Pakistan, India, Mexico, and Iran account for most of these cropland [3]. The current population of Pakistan is ~200 million and is expected to reach ~244 million by the year 2030 [5]. Pakistan being water stressed would soon become water deficient due to the shortage of water for domestic, industrial and agricultural purposes [6].
