The invention includes a system and method for delivery and storage of an absorbent for solidification of liquid waste. The system includes a plurality of nestable containers configured to receive aqueous liquid to be solidified and forming a packet safe space when nested one within another. The system also includes a plurality of packets at least partially soluble in the aqueous liquid to be solidified. The containers include at least one packet and each packet contains a solidifier for use as an absorbent composition for the aqueous liquid to be solidified. A packet may be housed within the containers inside a packet safe space. The invention also includes an improved system and method for packaging a solidifier for solidification of liquid medical wastes.

A wastewater treatment system comprises a fluid conveyance, one or more filtration vessels, one-way valves, and a backwash collection conduits. The filtration vessels each have a vessel inlet and a vessel outlet. Filtration media is positioned between the respective vessel inlet and the respective vessel outlet. Each respective vessel inlet communicates with the fluid conveyance. Each one-way valve is located at the inlet of the respective filtration vessel to regulate a flow of fluid from the fluid conveyance into the respective filtration vessel and to prevent the fluid from exiting the respective filtration vessels through the one-way valves. Each backwash collection conduit communicates with each filtration vessel by a drain conduit, the drain conduit having an outlet that is above a top of a fluid volume in the backwash collection conduit so as to provide an air gap.

Provided are nanonets comprising a) a surfactant aggregate having an average aggregate diameter; and b) a polymer having an average particle diameter which average particle diameter is the same or smaller than the average aggregate diameter, wherein the nanonet has a diameter larger than the average particle diameter. Also provided are kits therefor and methods for sequestering non-water moieties from aqueous solutions using nanonets.

Chemical dispensers are provided that include a hollow body member including a bottom end configured to be disposed below a waterline and a top end configured to be disposed above the waterline. The hollow body member defines an interior space disposed between the bottom end and the top end that is configured to accept, through the top end, and hold therein a dissolvable chemical. The dispenser includes a buoyancy member surrounding the hollow body member and configured to provide buoyancy to the dispenser when placed in a body of water such that a first portion of the interior space remains above the waterline and a second portion of the interior space submerges below the waterline. An opening in the hollow body member allows sufficient water flow into the interior space below the waterline such that dissolution or partial dissolution of the dissolvable chemical below the waterline occurs.

The present invention relates to a method for disinfection and/or function control of a chlorine sensor, which is preferably used in water conditioning for medical or pharmaceutical purposes, a chlorine-containing solution different from the measurement solution being specifically supplied to the chlorine sensor at time intervals.

Disclosed herein are systems and processes for treating a Waste Stream comprising biosolids, the Waste Stream provided at varying flow rates and solids concentrations so as to achieve an SOUR of 1.5 mg O.sub.2/g/hr or less and an ORP of at least +300 mV. The system includes a biosolids manipulation device to adjust the volume of suspended solids as a percent of the total volume of the Waste Stream to five (5) percent or less; a chemical oxidant feed device to dose the Waste Stream with an oxidant such as chlorine dioxide, ozone, or similar oxidant, and a treatment vessel associated with said chemical oxidant feed device through which said Waste Stream flows, wherein said chemical oxidant feed device and said treatment device are configured so as to achieve a dose rate between 25 and 200 parts per million of the Waste Stream and substantially complete mixing of the oxidant within 30 seconds of dose delivery in the treatment vessel.

A compact, portable system and process separates dissolved and suspended solids from water containing high levels of those solids. Gas flotation is used with and oxidant as an initial stage. The resulting foam is dewatered in a fluid conveyance, with the gas being recycled to the flotation column, the foam sent to a holding tank and the water passed through one of a number of filtration vessels having granular filter media. As at least one filtration vessel is kept in operation filtering, another filtration vessel can be backwashed when the flow therethrough is diminished of the fluid level inside rises. Treated water is used for backwashing and provided to a collection conduit.

A dental instrument water supply filter includes a hollow cylindrical body which bounds an interior area. The interior area houses a plurality of iodinated resin particles. A pair of water permeable discs are positioned in the interior area of the body at opposed axial ends. End caps close the interior area of the body at the respective opposed ends, and each end cap includes a respective removable fluid fitting. Water that is used in connection with the operation of a dental instrument is passed through the filter. The filter provides filtration and reduces microorganisms in the water that is passed therethrough and also releases ions into the water that are effective to reduce the growth of contaminants in the water lines to the instrument.

The present invention provides systems, methods, and articles for stress reduction and sleep promotion. A stress reduction and sleep promotion system includes at least one remote device, at least one body sensor, and at least one remote server. In other embodiments, the stress reduction and sleep promotion system includes machine learning.

An inline drain sanitizing system, includes: a manifold assembly including an inlet port, an outlet port, and a treatment port, wherein: the inlet port is configured to be couplable to a condensate supply line and receive unsanitized condensate, and the outlet port is configured to be couplable to a condensate drain line and provide sanitized condensate; and a treatment subsystem configured to interface with the treatment port and process the unsanitized condensate to generate the sanitized condensate.
