Webb1 jan. 2016 · The sludge produced a WTP at Ghaziabad, India is investigated for physical and chemical characteristics. It consist of about 60% fine sand in grain size range 150-75μ. Silica, alumina, ferric oxide and lime constitute the major percentage of chemical components present in the sludge. Some heavy metals are also found in the sludge. WebbFor most types of sludge, the available pore volume varies between 40% and 80%, granules with a lower porosity probably contain layers that are impermeable to substrate. Small granules were found to have a considerably higher porosity and a higher maximum methanogenic activity than larger granules from the same sludge sample.
