How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

methods for the removal of heavy metals from wastewaters‚ however‚ are often cost prohibitive having inadequate efficiencies at low metal concentrations‚ particularly in the range of 1 to 100 mg/L. Some of these methods‚ furthermore‚ generate toxic sludge‚ the disposal of which is a burden on the techno-economic feasibility of treatment procedures [3]. The search for new technologies involving the removal of toxic metals from wastewaters has directed attention to biosorption‚ based on metal

1. As a new material to the Geopolymer concrete the paper sludge ash can be used as a replacement material to flyash and cement. 2. Bond strength test results were conducted on cylindrical specimens of size 100mm dia x 200mm height. From the Results we can see that the increase in percentage of paper sludge ash 10% increases the bond strength and then it will be decreased. The maximum value of bond strength is 8.65 N/mm2 in hot air
