A mechanical bar screen is available for backup in case the fine screen malfunctions. Wet weather flow enters the influent relief pump station through fine screens. When the flow coming to the plant exceeds the capacity of the influent pump station, the wet weather system is activated. Liquid sodium bisulfite is injected in the plant effluent after chlorination to remove the chlorine before it is released to the Tennessee River. Sodium hypochlorite is injected into the water to disinfect the treated plant effluent. The cleaned wastewater leaves the secondary clarifiers and enters a chlorine contact tank. Mighty Microbe Character Cards with Real Pics of Microbes.pdf A portion of the (RAS) flow called waste activated sludge (WAS) is pumped to thickeners to be thickened before dewatering. The (RAS) pumps return a portion of the sludge back to the activated sludge system to keep the food chain going for the microorganisms in the secondary influent wastewater. Sludge collected in the secondary clarifiers flow by gravity to a return sludge pump station. Wastewater called mixed liquor flows from the activated sludge system to secondary clarifiers. High purity oxygen is supplied for the microorganisms in the activated sludge system by an on-site, cryogenic air separation plant. Microorganisms are used to convert suspended and dissolved solids to settleable solids.

The secondary treatment process is a biological activated sludge high purity oxygen process. Equalization pumps pump the wastewater from the basins to the activated sludge process. Blowers provide air to the equalization basins to keep the solids suspended and prevent the wastewater from going septic. The equalizations basins are used to store water during high flow conditions and to create a constant flow rate to the secondary treatment system. The treated primary wastewater next enters the equalization basins before secondary treatment. Raw sludge is pumped to the gravity sludge thickeners and floating scum is removed and screened and dewatered through rotating basket type screens. Raw sludge and floating scum is collected in the primary system. 25 inches in size.įlow leaves the grit removal system and enters the primary settling basins. The screens remove cigarette filters and other pieces of debris smaller than. After screening, the wastewater is pumped to the grit removal system and more screening.ĭetritors are used to remove grit, rock, sand and gravel from the raw wastewater before it passes through fine screens The screens remove large pieces of paper, rags, leaves, plastic bottles and tin cans. Raw wastewater enters the Moccasin Bend WasteWater Treatment Plant influent pump station wet well through bar screens. HISTORY of Wastewater Treatment in the U.S. MAP Process Legend Liquid Handling Systems SCUM launches for Steam early access on August 29, 2018.Permit Number TN0024210 Summary Descriptions of Moccasin Bend Wastewater Plant Systems Still, since nobody is quite sure how even the Call of Duty Battle Royale mode will turn out, this might be one to watch. SCUM's streaming embargo just lifted this morning, so it's possible streams will lower as time goes on. The game engine even accounts for movement inertia. A wetness and drying system influences your body temperature. Metabolism systems determine whether you are thin, obese, or muscular. There are dozens of systems interacting with each other at all times, some of which may not be obvious to players. Second, SCUM leans heavily into the 'simulation' side of survival sim. There is no shrinking map to direct your focus, so players will spend lots of time wandering without encountering another soul. Unlike the Battle Royale competition, SCUM stands out in two areas. In each match, 64 'participants' are taken from a supermax prison and dropped into TEC1's 144 square kilometer island and fight for their lives - and the gifts of sponsors. SCUM is set in a world where criminals fight to the death for the entertainment of a bloodthirsty audience. Not only does it put a new spin on familiar mechanics, but it's also drawing lots of attention from Twitch streamers - second only to Fortnite itself. Take SCUM, the survival game from Gamepires and Croteam which enters early access later this week. You might think Battle Royale games are becoming common, but apparently some players aren't quite finished with them quite yet. SCUM may not even be in early access yet, but Twitch streamers have absolutely found something intriguing here.
