Abstract
In this work different samples of wastewater were collected from sewage pipe of speed packages a printing and packaging industry near Band Road Daroghawala Lahore. Different experiments were taken place for the purpose of waste water analysis.It is very important to reduce or remove such harmful substances and heavy metals from flexographic printing wastewater before its removal into lakes underground water, ponds, river and streams.It was seen that effluents from flexographic printing industry have great and harmful side effects for human and animal especially for aquatic life. A number of diseases such as asthma, ageing, lung and kidney diseases and disorder of central nervous system before treatment flexographic printing based polluted waste water possess greater amount of suspended particles 1940 mg/L, dissolved solids 2170mg/L, high conductivity 1033 μS/cm, chemical oxygen demand 956 mg/L, biological oxygen demand 145 mg/L and high pH 7.91 and reasonable amount of heavy metals iron1.8 mg/L, Lead 11mg/L and zinc 7 mg/L. In this work water was treated to reduce above discussed parameters and heavy metals by using wheat straw, rice husk, animal charcoal and mixture of them. After the treatment, all of material shows different values but Animal charcoal show result of Ph=7.58, conductivity (353μS/cm), Total Hardness (356mg/L), Total Dissolved Solid (356mg/L) Total Suspended Solid (430mg/L), Chemical Oxygen Demand (167mg/L) and Biological Oxygen Demand (334mg/L)heavy metals iron 0.6 mg/L, Lead 3.2 mg and zinc 2.1 mg/L. In all these treatmentsanimal charcoal show good results than others.
