Abstract: 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.

Abstract: A method of controlling addition rate of an odor control chemical to a wastewater line by adding odor control chemical to the wastewater. The method includes measuring a level of dissolved sulfides in the wastewater line using a sulfide probe placed in said wastewater line, transferring data on the level of dissolved sulfides to a computing unit, determining a required odor control chemical addition rate in said computing unit based on said level of dissolved sulfides, and adding the odor control chemical at said required addition rate. The method allows for accurate on-line control of the level of H2S in the wastewater line.

Abstract: A slow-release method for treating non-point source pollutants traveling in water runoff, such as urban water runoff. Method embodiments include the use of slow-release advanced oxidation process forms (SR-AOPs) comprised of one or more water soluble salts in a matrix and/or forms producing hydrogen peroxide, persulfate anion, and/or permanganate. One or more of such forms may be placed along with one or more slow-release iron forms in the path of runoff water as it flows through a storm sewer system, such that an amount of the water soluble salt(s) and/or hydroxyl radicals (Fenton's reagent), persulfate radicals, or permanganate are slowly released into the runoff water to oxidize the pollutants contained therein.

Abstract: The instant invention describes a device and system for dispensing microbial solutions into a wastewater treatment environment. The device contains one or more removable modules that provides the user with the capability of quickly and easily removing one or more of the modules without the need for replacing or removing the entire unit. The modules are preferably designed to hold bags filled with a microbial solution. The bags are fluidly connected to a pump which dispenses the solution to a predetermined location.

Abstract: A system and method of treating wastewater within a wastewater network, such as a sewer system, to control odor (primarily from sulfides and H2S), FOG (fats, oil, and grease), and corrosion in a distributed wastewater or sewer system. The system and method comprise generating bacteria using an on-site biogenerator, feeding the bacteria into the wastewater, mixing the wastewater and adding oxygen with an aerator/mixer to maintain dissolved oxygen levels of at least 0.5 ppm (if needed), and adding supplemental treatment chemicals (if needed). The system and method preferably comprise monitoring the wastewater and controlling feed rates of bacteria, oxygen and supplemental chemicals based on the results of monitoring.
