A cartridge assembly for dispensing a disinfecting water is disclosed. The cartridge assembly has a cartridge for receiving water from a container and a water dispensing mechanism for receiving water from the cartridge and delivering the water to a surface. The cartridge holds an iodinated resin for eluting a quantity of iodine into the water passing through the cartridge. When the water dispensing mechanism is actuated, water is delivered from a container to the water dispensing mechanism and the water is delivered to the surface to be disinfected.

Techniques and systems for neutralizing discharge waters from ballast and/or cooling water biocidal treatment and disinfection systems are provided. The systems utilize, inter alia, oxidation reduction potential control to regulate the dechlorination of an electrocatalytically generated biocidal agent to allowable discharge levels in ship buoyancy systems and ship cooling water systems.

A ballast water treatment apparatus and a ballast water treatment system having a ballast water treatment apparatus are provided. The ballast water treatment apparatus includes a ballast water transport line configured to transport ballast water between a first location and a second location, the transported ballast water being passed through at least one injector, and a plasma generation device configured to be fed with a feed gas optionally comprising oxygen, and configured to generate a feed gas plasma by a streamer type discharge in a discharge area to provide a treated gas at a treated-gas outlet. The injector includes a liquid passage having an area constructed such as to increase a velocity of the passed-through water in a region of increased velocity, and an injector gas inlet provided in the region of increased velocity. The treated-gas outlet is in gaseous connection with the injector gas inlet.

There is provided a method for controlling bio-slimes in a clean circulating water system through a physical-chemical-superconducting high gradient magnetic separation coupling process. An inorganic composite flocculant is added to circulating water to gather Zoogloea in the circulating water with micro-nano particles in hydrosol through demulsification to form alum floc. The resulting water passes through a superconducting high gradient magnetic separation system. A magnetic field strength of the superconducting high gradient magnetic separation system and flow rate of the circulating water are controlled to generate strong magnetic flocculation to allow floc to grow, such that the Zoogloea in the circulating water wraps the micro-nano particles to separate the Zoogloea from water.

A system for the treatment of microorganisms includes: a textile web having optical fibers in warp and/or weft woven with binding threads in warp and/or weft, each of the optical fibers having invasive alterations along the fiber and allowing the emission of light propagating in the fiber at these alterations; a light source arranged opposite one or both free ends of the optical fibers. The textile web includes metallic warp and/or weft threads woven with the binding threads, the metallic threads being based on a metal having a negative effect on the growth of microorganisms. The light source generates a light beam having at least one wavelength in the visible or ultraviolet spectrum.

Provided are a bacterium for degrading sludge having a 16S rRNA gene comprising a nucleotide sequence having 97% or more identity to the nucleotide sequence represented by SEQ ID NO: 1, a bacterium having a 16S rRNA gene comprising the nucleotide sequence represented by SEQ ID NO: 1 with mutations of two bases or less, and having an ability to degrade a target microorganism, and a microbial preparation for degrading a target microorganism comprising a bacterium (a1) below. Bacterium (a1) is a bacterium having a 16S rRNA gene comprising a nucleotide sequence having 90% or more identity to the nucleotide sequence represented by SEQ ID NO: 1.

A water purification electrolytic generator apparatus provides clean drinking water to users. An electrolyte is added to water/other liquid exposed to the electrolytic generator apparatus in order to create an environment suitable for the apparatus to function . Residing in a housing of the apparatus is an enclosed first electrode (cathode) printed on a printed circuit board, a second electrode (anode), and a membrane separating the cathode and anode/printed circuit board. A control circuit including the printed circuit board electrically connects the anode and cathode to a power source, which is located external to the interior of the container. The incorporation of the printed circuit board reduces costs and improves portability so that the water purification system can provide drinkable water to users in different circumstances. A system including the apparatus may further include a container housing the electrolytic generator apparatus, a lid, and a stand. A filter is positioned in the container to filter water poured into the container.

Various embodiments of the present invention relate to, among other things, a nano carrier platform for generating enhanced engineered water nanostructures (iEWNS) encapsulating and delivering reactive oxygen species (ROS) and, in some instances, other active ingredients, methods for inactivating at least one of viruses, bacteria, bacterial spores, and fungi on a substrate by applying iEWNS to the substrate.

A membrane separation pretreatment apparatus including a membrane separation unit and a first underwater plasma discharge unit disposed in front of the membrane separation unit is provided. The membrane separation pretreatment apparatus includes a membrane separation unit configured to remove particulate matter contained in raw water, and a first underwater plasma discharge unit disposed in front of the membrane separation unit and configured to cause a portion of the raw water to be introduced into the membrane separation unit to perform underwater plasma discharging.

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.
