摘要： The disclosed lagoon biological treatment system helps existing wastewater treatment facilities meet stricter discharge permits mandated by the EPA utilizing a facility's existing wastewater treatment infrastructure. Influent is pumped into and processed in an aerated or non-aerated lagoon system, thus initially treating the wastewater to reduce BOD5 (Biochemical Oxygen Demand) and TSS (Total Suspended Solids) to approximately 20-30 mg/L. Then the wastewater is transferred to and processed in a nitrification reactor, where sufficient nitrifying bacteria is present to reduce nitrogen levels to regulation-acceptable levels without needing to regulate temperature of the water in the nitrification reactor. Wastewater may also be further processed in a denitrifying reactor if necessary to meet local requirement. Post-nitrification polishing of the wastewater is foregone.

摘要： This specification describes a membrane aerated biofilm media and reactor (MABR) having a discontinuous layer of a porous material applied to the outer surface of a gas-transfer membrane. The porous material may have a void fraction of 50% or more. The porous material may have a thickness of up to about 500 microns and a pattern on the same order of magnitude as its thickness. The media may be used to carry on a deammonification reaction. In use, ammonia oxidizing bacteria (AOB) and annamox bacteria grown in or on the media, with the annamox bacteria located primarily in the porous material. The supply of oxygen through the gas-transfer membrane is limited to suppress the growth of nitrite oxidizing bacteria (NOB). Excess biofilm is removed, for example by coarse bubble scouring. The media may be placed in an anoxic zone of an activated sludge plant, which may be upstream of an aerobic zone.

摘要： Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.

摘要： A horizontal flow water treatment method and wetland biofilter system with improved flow control via a tubular apparatus and further comprising a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

摘要： A system for thermally bonding nonwoven fibers of assemblages of nonwoven fibers loosely held together may include a processing duct including an inlet end, an outlet end, and an intermediate portion extending between the inlet end and the outlet end. The system also may include one or more heat inlets located in the intermediate portion and configured to facilitate introduction of heat and air flow into the intermediate portion. The system further may include an inlet air feed at the inlet end and configured to separate the assemblages upon entry into the inlet end and propel the assemblages into the intermediate portion. The system also may include one or more heating devices configured to heat the assemblages as the assemblages are conveyed toward the outlet end to form processed assemblages, each of the processed assemblages including at least some nonwoven fibers adhered to one another.

摘要： The subject of this invention is to use beneficial reactive support media in the form of reactive support bases or stratums that provide structural or biochemical benefits to the growth or function (including agglutination) of biofilms. The functional aspect includes the provision of a polymeric, cellulosic or silicic framework. The framework could also contain charge moieties such as cations, anions, amines or carboxyl groups whose pKa's allow them to be charged at the physiological pH for an organism. For example, a cation may provide a positive charge to help the adherence of a negative charge exocellular polymeric substance. The reactive support media may include biodegradable or refractory plastics, alginates or uronic acids or extracted bacterial EPS. These materials are reacted, retained or removed based on their physical characteristics.
