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
