Sludge

In the Sludge Lab our overall objective was to sucessfully separate a sample of Sludge into separate the different materials that make it up. We did this by using various methods of separation such as filtration, sifting, evaporation, removing by hand, and fractional distillation to achieve this. Once we had all the pure substances we began testing their characteristic properties. We used several characteristic properties to identify the pure substances. For the liquids we tested flammability, density

evaluation of the entire treatment process along with biological treatment process particularly suspended growth process Activated Sludge Process (ASP), attached growth process Trickling Filter (TF) and a combination of the both suspended and attached growth process Hybrid Reactor (HR) is presented in the following sections of this chapter. 2.2 REVIEWED OF LITERATURE ON ACTIVATED SLUDGE PROCESS In suspended growth processes, the microorganisms responsible for the treatment of wastewater are maintained in liquid

sewer system and an anticipated future increase in wastewater generation, the plant is currently undergoing a major expansion to increase its capacity from 2 MGD to 6 MGD, with a peak design of 15 MGD. The new treatment plant will used an activated sludge process called the Modified Ludzack-Ettinger (MLE) Process, which consists of a continuous-flow suspended-growth process with an initial anoxic stage, followed by an aerobic stage; used to remove total nitrogen. During the study, the treatment scheme

Sludge Test Conclusion - Zoey Xeros and Lauren Head A clear, colorless liquid was separated using fractional distillation. The identity of this unknown liquid was found by the characteristic properties of flammability, density, sugar solubility, boiling point, and odor. The liquid ended up being flammable, and the density was below the average 0.79 g/cm3. Instead, we found 0.69 g/cm3. For the sugar solubility, it was found to be insoluble. The boiling was found to be higher than the average is 57C

reduce the photosynthetic ability of plants. In addition, such hazardous waste is primarily generated at growing rates, by various industries which utilize petroleum products as energy sources and raw materials. The effective remediation of oily sludge has become a worldwide problem due to its hazardous nature and increasing production quantity around the world. More specifically, in third world

Sludge Test Conclusion (B211) The original sludge we received was a dark, foggy, yellow color with three insoluble solids submerged in the liquid mixture. After further observation, we saw medium sized chunks of black solid at the bottom of the sludge bottle. There were also tiny, clear spheres of solid and small, silver solids in the shape of disks. The sludge smelt like alcohol or acetone. After testing our sludge, we found a total of two liquids and four solids. One of the liquids we found in

rate of QF = 80m3 d-1 to the SNdN activated sludge system. The SNdN system actually functions as an autonomous treatment plant where oxidation of organic pollutants, nitrification/denitrification and suspended solids sedimentation are taking place. Furthermore a sludge recycling from the secondary clarifier to the aeration tank is performed so as to ensure the required microbiological load (5000 ± 450 mg L-1). The aeration tank of the SNdN activated sludge system operates under low D.O. concentration

“We cursed through sludge” The first two lines provides the reader with an unexpected view on a soldier as soldiers are generally seen as strong athletic man. In the second stanza the an important moment happens, poisonous gas forces the soldiers to put their helmets on. Owen heightens the tension through the depiction of one unlucky soldier who could not complete this task in time - he ends up falling, "drowning" in gas. This is seen through "the misty panes and the thick green I saw him drowning

Tennessee Coal Sludge Disaster What Happened? The largest environmental disaster in U.S. history occurred on December 22nd, 2008 when a 84-acre pit containing toxic coal combustion residue at the Tennessee Valley Authority Fossil Plant in Kingston, Tennessee gave way. According to a report by AECOM, the firm hired to perform the root cause report, a “combination of the high water content of the wet ash, the increasing height of ash, the construction of the sloping dikes over the wet ash,
