Assessment of Pollution Load in Marble Waste Water and their Utilization (P-0792) (MFN 5503)

Abstract

The current research was conducted to investigate pollution load in marble wastewater of marble industries in Khairabad District Nowshera Khyber Pakhtun Khwa (KPK) Pakistan and role of marble industries to pollute river kabul passing through Jehangira and Khairabad District Nowshera KPK. Also this study includes possible utilization for marble waste and control of marble waste. For this purpose water sample are taken from different locations along the length of river kabul and from marble industries. Physical parameter like pH, temperature, colour , electrical conductivity were analysed on field and some other parameters like Total Suspended solids (TSS) and Total Dissolved Solids (TDS) were analysed in laboratory using standard methods. The results were compared with standard values of National Environmental Quality Standards (NEQS).Settling tank were constructed in marble industry for collection of TSS. TSS is then removes from settling tanks and dry in sun light which is then converted into powder form. Mixing of marble powder in different ratio with cement and concrete and made different products like construction blocks and decoration pieces. The results show that almost all physical parameters were found under permissible limit of NEQs of Pakistan except electrical conductivity and TSS in some industrial effluents. Comparison of results of sample collected from river before marble industries and after industries shows a little difference in pH, Temperature, Electrical conductivity and in TSS. Mixing of waste marble powder with cement, concrete in different ratio has positive result in construction blocks. According to current research suggested that marble waste powder can be easily utilized in construction blocks. However detailed study should be conducted for more utilization options of marble waste and analysis of heavy metals in marble industries effluent
