Milorganite is the trademark of a biosolids fertilizer produced by the Milwaukee Metropolitan Sewerage District . The name Milorganite is a contraction of the phrase Mil waukee Orga nic Nit rog e n, and was the result of a 1925 naming contest held in National Fertilizer Magazine . The biomass from activated sludge is heat dried to 95 solids and pelletizing at the Jones Island Water Reclamation Facility in Milwaukee, Wisconsin Milwaukee , Wisconsin . Mistakenly, Milorganite 6 2 0 is referred to as a compost , which it is not. Compost are blends of thermophilic organic materials, with higher moisture, lower nitrogen and much higher application rates. Raising taxes for public health was relatively controversial in the early 1900s. In 1911, reform minded Milwaukee Sewer Socialists were elected on a platform calling for construction of a wastewater treatment plant to protect against water borne pathogens. ref Chifford Mortimer, The Lake Michigan Pollution Case, Center for Great Lakes Studies, UWM May 1981 , p. 2 3 fig. 1, incidence of typhoid fever compared to water purification and wastewater treatment improvements . ref Experiments showed that heat dried activated sludge pellets compared favorably with standard organic materials such as dried blood, tankage, fish scap, and cottonseed meal. ref Eleventh Annual Report of the Sewerage Commission of the City of Milwaukee for 1924, pages ... before discharged to Lake Michigan.

In vessel composting is an Industry industrial form of composting biodegradable waste that occurs in enclosed reactors. These generally consist of metal tanks or concrete bunkers in which air flow and temperature can be controlled, using the principles of a bioreactor . Generally the air circulation is metered in via buried tubes that allow fresh air to be injected under pressure, with the exhaust being extracted through a biofilter , with temperature and moisture conditions monitored using probes in the mass to allow maintenance of optimum aerobic decomposition conditions. This technique is generally used for municipal scale organic waste processing, including final treatment of sewage biosolids , to a safe stable state for reclamation as a soil amendment. In vessel composting can also refer to aerated static pile composting with the addition of removable covers that enclose the piles, as with the system in extensive use by farmer groups in Thailand, supported by the National Science and Technology Development Agency there. ref http www.compost.mju.ac.th eng Aerated Static Pile composting ref Offensive odor s are caused by putrefaction anaerobic decomposition of nitrogenous animal and vegetable matter gassing off as ammonia . This is controlled with a higher carbon to nitrogen ratio , or increased aeration by ventilation, and use of a coarser grade of carbon material to allow better air circulation. Prevention and capture of any gases naturally occurring volatile organic compounds during the hot aerobic composting involved is the objective of the biofilter, and as the filtering material saturates over time, it can be used in the composting process and replaced with fresh material.

unref date June 2011 Image Jet aerator at paper mill.jpg thumb Jet aerators operating in a waste sludge tank at a paper mill. Jet Aerators transfer oxygen by simutaneously introducting large volumes of high kinetic energy liquid and air through a series of jet nozzles. The high velocity exits the inner, primary jet and rapidly mixes with the incoming air in the outer jet. This intense mixing and high degree of turbulence in the gas liquid cloud travels outward from the jet along the basin floor prior to the vertical rise of the gas bubble column to the liquid surface. Applications, Features and Benefits Examples of applications where jet aerators are commonly applied Jet aeration technology is applicable across a wide range of wastewater and biosolids treatment applications including Air Activated Sludge, SBR, MBR, MBBR, Oxidation Ditch, Aerated Stabilization Basins, Equalization Tanks, Aerobic Digesters and ATAD. Oxygen Transfer Efficiency And Energy Savings In most industrial wastewater and biosolids applications jet aerators exhibit superior oxygen transfer efficiency compared to other aeration technologies. The hydrodynamic conditions within the jet and fine bubble cloud produces continuous surface renewal at the gas liquid interface resulting in higher alpha factors. This results in superior process oxygen transfer performance in the presence of surfactants, extrecelluar enzymes and high MLS concentrations. Process Flexibility Jet aerators are easily configured into any basin geometry including circular, retangular, looped reactors and sloped wall basins. Jet aerators are ideally suited for deep tank processes. The jet oxidation ditch is an example of technology innovation where the combination of a deeper basin design, bottom to top mixing and conservation of momentum combines to make a very efficient treatment process. In this and other applications the independent control of oxygen transfer and mixing is a valuable feature for both process control and energy ... more details

With headquarters and a central laboratory along the Menomonee River near downtown Milwaukee, Wisconsin Milwaukee , it has two wastewater treatment plants which are located at Jones Island, Milwaukee Jones Island Coord 43 01 23.5 N 87 53 58 W in Milwaukee and at the South Shore Coord 42 53 16 N 87 50 44 W in Oak Creek, Wisconsin Oak Creek . These facilities were operated by United Water under a 10 year agreement ending March 1, 2008. Veolia Water is the current operator. The primary wastewater treatment plant at Jones Island was one of the first of its kind when the original activated sludge plant was constructed in 1925. MMSD was the first to market biosolids created through this process as a fertilizer under the name Milorganite . The 1925 plant has been designated as a Historic Civil Engineering Landmark by the American Society of Civil Engineers . During the past few years, sewage has been dumped into Lake Michigan either by accident or as a result of sewer overflow. By late March, 2006 the Milwaukee Metropolitan Sewerage District had accidentally dumped 800,000 gallons of sewage into Lake Michigan. The accidents occurred as workers at the Jones Island facility were testing a new computer operating system. Testing was done under the United Water contract.

No footnotes article June 2007 date August 2009 File Rotary vacuum drum filter.svg thumb 420px Oliver type rotary vacuum drum filter. Rotary vacuum filter drum consists of a drum rotating in a tub of liquid to be filtered. The technique is well suited to high solids liquids that would blind or block other forms of filter. The drum is pre coated with a filter aid, typically of diatomaceous earth DE or Perlite . After pre coat has been applied, the liquid to be filtered is sent to the tub below the drum. The drum rotates through the liquid and the vacuum sucks liquid and solids onto the drum pre coat surface, the liquid portion is sucked by the vacuum through the filter media to the internal portion of the drum, and the filtrate pumped away. The solids adhere to the outside of the drum, which then passes a knife, cutting off the solids and a small portion of the filter media to reveal a fresh media surface that will enter the liquid as the drum rotates. The knife advances automatically as the surface is removed. See also Vacuum ceramic filter Dewatering Further reading cite book first Paul G. last Smith coauthors John S.

Wet oxidation is a form of hydrothermal treatment. It is the oxidation of dissolved or suspended components in water using oxygen as the oxidizer . It is referred to as Wet Air Oxidation WAO when air is used. The oxidation reactions occur in superheated water at a temperature above the normal boiling point of water 100 C , but below the Critical point thermodynamics critical point 374 C . The system must be maintained under pressure to avoid excessive evaporation of water. This is done to control energy consumption due to the latent heat of vaporization . It is also done because liquid water is necessary for most of the oxidation reactions to occur. Chemical compound Compounds oxidize under wet oxidation conditions that would not oxidize under dry conditions at the same temperature and pressure. Commercial applications Wet oxidation has been used commercially for around 60 years. It is used predominantly for treating wastewater . It is often referred to as the Zimpro process, after Fred T. Zimmermann who commercialized it in the mid 20th century. ref cite web url http www.water.siemens.com en about us legacy brands Pages zimpro.aspx title Zimpro History accessdate February 2010 ref Commercial systems typically use a bubble column reactor , where air is bubbled through a vertical column that is liquid full of the hot and pressurized wastewater. Fresh wastewater enters the bottom of the column and oxidized wastewater exits the top. The heat released during the oxidation is used to maintain the operating temperature . The majority of commercial wet oxidation systems are used to treat industrial wastewaters, such as sulfide laden spent caustic streams. Almost as many systems are also used for treating biosolids , in order to pasteurize and to decrease volume of material to dispose of. A special type of process was the so called VerTech process .
