A water filter system that includes a base that receives water from a faucet, where the base includes a bottom support and a vertical support transversely extending from the bottom support. The vertical support includes a visual light display having visual indicators that indicate different parameters of the filter system. A filter cartridge is seated in the base, and defines a first chamber having at least one filter element, and a second chamber in fluid communication with the first chamber. An enhancement cartridge is removably inserted in the second chamber of the filter cartridge and includes an enhancement material for adding minerals to the water. A cover having an opening is configured to slidingly engage the vertical support of the base so that the visual light display is positioned within the opening of the cover and visible to a user.

A device for monitoring the level or amount of a material within a container is provided. The device includes a detection mechanism that can be a direct detection mechanism or an indirect detection mechanism. When the detection mechanism senses an upper level of the substance in the container that is below a predetermined lower limit for the substance, the mechanism operates an alarm mechanism to emit an alarm to alert an individual to the low level of the substance within the container. The alarm can wirelessly communicate a salt level state to a wireless network or a device on a wireless network that can transmit the status through the Internet to any remote location. In one aspect, the alarm can be sent on a mesh network with a device that can transmit the status and other conditions through the Internet and to an application executing on a mobile device.

A feeding head assembly and a chemical release system for eliminating scale conditions and maintaining a neutral pH in potable water is disclosed. The feeding head assembly may include a composite membrane system comprising at least one semi-permeable layer and at least one filter layer. A chemical release system may include a cartridge or vessel. The cartridge may include a hollow body with two opposing open ends. A time-release pouch may be located within the hollow body and holds a composition that mixes with potable water to eliminate scale conditions and maintain a neutral pH in the potable water. A feeding head assembly may be coupled within the hollow body between the time-release pouch and one open end of the hollow body.

A water quality converter includes: a container having an oval hollow, where the container is a plastic body of a mixture in which 10% to 30% by weight of aventurine, 5% to 20% by weight of sodalite, 2% to 10% by weight of amethyst, 1% to 10% by weight of Chungito, 5% to 20% by weight of germanium, 2% to 10% by weight of Shungite, 3% to 10% by weight of elvan, 2% to 10% by weight of rose crystal, 1% to 5% by weight of seven-colored gemstone, and 1% to 5% by weight of wooden stone are mixed, and a weight ratio of aventurine to sodalite ranges from 3:1 to 1:1, a weight ratio of aventurine to germanium ranges from 2:1 to 1:1, a weight ratio of germanium to Shungite ranges from 4:1 to 1:2, and a weight ratio of amethyst to germanium ranges from 1:2 to 1:5.

A method for waste material treatment that results in a more stable, entombed treated waste product. A reactive treatment formulation can be dispensed with a waste material deposit into a self-contained non-contact agitating toilet to form a stabilized viscous mass. The reactive treatment formulation mixed with the waste material deposit prevents odors, bacterial growth, and stabilizes the waste material into a treated waste product to reduce spillage during disposal.

A system and method for delivering silver ion biocide is described herein. The systems described relate to passing water from a water system through a silver ion release module and optional high-concentration silver ion release module. The system includes an analyzer, detector, and/or controller for monitoring the concentration of silver ion and adjusting the flow path, flow rate, temperature and/or pH of the water in order to obtain the desired concentration of silver ion. The system optionally includes other metal ions released into a water system, the concentration of which may be used to automatically calibrate the described system and/or cause the system to take actions based on the measured concentration of silver ion or of the second metal ion.

The invention proposes a process of in-line mineralisation of water according to which demineralised water is circulated in a pipe inside which enzymes are immobilised to catalyse the reaction of carbon dioxide and water to form bicarbonate, carbon dioxide is introduced into the pipe, and a pre-determined quantity of solid minerals, preferably magnesium and/or calcium carbonate, is introduced into the circulating water. The process enables to accelerate the dissolution of carbon dioxide in the water, which optimises the dissolution of minerals for in-line mineralisation of water, i.e. without stopping the circulation of water. The invention also proposes a system for implementing the process.

An apparatus for the extraction of phosphorus from wastewater that includes a precipitation module and a retention module. The precipitation module includes a crystallization vessel, one or more inlets disposed in a lower region of the precipitation module and at least one outlet disposed in an upper region of the precipitation module. The retention module includes a sedimentation vessel, at least one inlet disposed in an upper region of the retention module and at least one outlet disposed in a lower region of the retention module. At least one outlet of the precipitation module is connected to at least one inlet of the retention module and at least one outlet of the retention module is connected to at least one inlet of the precipitation module. The volume VS of the sedimentation vessel is greater than/equal to 0.6 times the volume VC of the crystallization vessel (VS≧0.6.Math.VC).

A drop-in treatment apparatus and system for PFAS-impacted liquids. The drop-in treatment apparatus and system may comprise one or more cartridges having a plurality openings; one or more mesh containers disposed within the one or more cartridges; one or more tethers; a submersible pump coupled to the cartridges via the tethers; and a power source electrically coupled to the submersible pump. The drop-in treatment apparatus may further comprise a plurality of prescribed masses of sorbent or resin filled within the mesh containers, such that the prescribed masses of sorbent or resin are disposed within the cartridges. The prescribed masses of sorbent or resin may be configured to remove PFAS compounds from a liquid and may be in the range of 0.1-50,000 milligrams per milliliter of liquid volume to be treated. The sorbent may be pyrogenic carbon, granular activated carbon, biochar, zeolite, aluminosilicates, and combinations thereof.

A ballast water treatment system includes: a chemical agent container for containing a chemical agent for a ballast water treatment; a chemical liquid preparation tank having a tank main body for containing the chemical agent supplied from the chemical agent container and water for dissolving the chemical agent, and a mixture part for mixing the chemical agent with the water in the tank main body; a chemical liquid storage tank for storing the chemical liquid obtained by dissolving the chemical agent in the water in the chemical liquid preparation tank; and a chemical liquid supply part for supplying the chemical liquid stored in the chemical liquid storage tank into ballast water.
