A system and method for monitoring and altering the conditions of a sewage system comprising a wet well connected to a sewer. The wet well is also configured to provide sewage to a secondary system, where the sewage is fed into an oxygen contact chamber. That chamber is fed oxygen which is dissolved into the sewage such that the sewage in the contact chamber has elevated oxygen content. That oxygenated sewage is then fed into the sewage system in order to raise oxygen levels and control anaerobic activity. Sensors and valves of the system are controlled by a central controller which provides for improved functionality, energy savings, and automated function.

A cost effective and environmentally sound method of controlling hydrogen sulfide in a wastewater collection systems comprising administration of anaerobic sulfide oxidizing bacteria along with limited amounts of nitrate.

There is provided a removable downspout filter for installation into a downspout. The removable downspout filter includes a filter basket with attached face plate. The face plate includes side flaps configured to wrap around the downspout when the downspout filter is installed and is generally configured to blend in with the downspout. Also provided is a downspout with installed filter and kits including the same.

A device (1) for cleaning a fluid (3) contaminated with oil, comprising a filling (7) made of a material that absorbs the oil (2), which filling is located inside a container (4) and is arranged between an inlet and an outlet (5, 6) of the container (4). According to the invention, the absorption property and handling of the filling (7) is increased by virtue of the fact that the filling is formed by a package-type tangle of keratin structures (8) that are randomly arranged and stochastically distributed in all three dimensions, which in the operating state of the device (1), comprise a closed container edge (9) between the inlet and the outlet (5, 6), and rest thereon in a liquid-tight manner.

Compositions for the use of sewage or wastewater treatment, controlling odors or a combination thereof are disclosed, wherein the composition comprises at least one iron-based compound. Furthermore, methods of reducing the odors in a sewage or wastewater system are disclosed that include: adding a composition comprising at least one iron-based compound to a sewage or wastewater system. As used herein, the phrase at least one iron-based compound includes ferrous chloride, ferric chloride, ferrous sulfate, ferrate, polyferric sulfate, Ferix-3 (Fe.sub.2(SO.sub.4)3H.sub.2O) or a combination thereof.

Various aspects of this disclosure relate to toilet systems that include compositions to inhibit wastewater from freezing in a waste tank of a toilet. A first fluid treatment composition comprises a salt that is introduced into the waste tank. A second fluid treatment composition is a solid composite that also comprises a salt and that is introduced into a urinal in fluid communication with the waste tank.

A storage container includes an input portion for receiving and filtering a source liquid to form an output liquid, a storage portion for storing the filtered liquid, and a base portion disposed below the storage portion including a UV light source for providing transmitted UV light to the filtered liquid, a UV light detector disposed an optical path length away from the UV light source for detecting received UV light through the filtered liquid in response to the transmitted UV light, a processor for determining an absorption or a transmission percentage in response to the transmitted UV light and the received UV light, for determining a safe condition, in response to the absorption or the transmission percentage respectively not exceeding or exceeding predetermined criteria, and one or more indicators for indicating that the liquid is safe for consumption to a user, in response to the safe condition.

A drain is positioned in an aperture in a floor surface. The drain includes a flange that defines an opening, extends overt the floor surface and engages the floor surface. A first conduit is connected to the flange and extends through the aperture in the floor surface. The first conduit defines a first length extending downward from the flange and also defines a first perimeter. A second conduit is connected to the flange and extends through the aperture in the floor surface. The second conduit defines a second length extending downward from the flange, and defines a second perimeter. The second perimeter is greater than the first perimeter, the second conduit surrounds the first conduit, the second conduit is outwardly spaced from the first conduit, and the first conduit and the second conduit are coaxial.

The disclosure relates to an apparatus, system, and methodology for treating nested waste matter, including a delivery system for delivering a volume of untreated material; a confined container having an inlet connected to the delivery system; an energy impingement device introduced transversely into said confined container, where the energy impingement device is configured to deliver a volume of injected fluid and further configured to treat the volume of untreated material in said confined container and wherein the confined container has an outlet for exiting a volume of treated material.

Compositions and methods and systems for treating wastewater within a wastewater treatment system of described. In an embodiment, a composition for treating wastewater within a wastewater treatment system and for preventing or reducing the occurrence of struvite scale formation within the wastewater treatment system may include an admixture including a magnesium compound. The admixture may also include a dispersing agent. The admixture may further include at least one of a free magnesium control agent and a seed material. Other compositions and methods are described.
