A system in which water flowing through the system flows in proximity to an ion generation device and to a UV radiation source combines silver photochemistry principles, heavy metal toxicity, and UV radiation to form a highly effective combined water disinfection process. Using ion generation and UV irradiation, the system synergistically improves the disinfection and bactericidal effects of ion generation or UV radiation working individually by making ion-exposed microorganisms more susceptible and less resistant to the bactericidal effects of UV radiation. The UV radiation source uses a manual wiping system to remove buildup that is a result of water supply minerals attaching to quartz sleeves used within the UV radiation source. The present invention introduces a device or other obstructive structure that creates a flow pattern that provides additional “wiping” of the quartz sleeves on a continual basis in conjunction with manual wiping.

A cartridge carrier having a skeleton housing with a cartridge cradle for supporting a cartridge dispenser therein and a connector on the skeleton housing for supporting a further dispensing cartridge outside of the skeleton housing.

This specification describes membrane based filtration and softening systems and methods. A system has a microfiltration or ultrafiltration (MF/UF) membrane unit upstream of a nanofiltration or reverse osmosis (NF/RO) membrane unit, optionally with no intermediate tank. In some cases, the system and method may be used with feed water provided at municipal line pressure to the membranes. NF/RO permeate is collected in a tank and then pumped to a header. Treated water may be drawn from the header for use or recycled to the system, for example to backwash or flush one or both of the membrane units. In a combined process, NF/RO permeate flushes the feed side of the NF/RO unit and then backwashes the MF/UF unit. In another process, the MF/UF unit and NF/RO unit are filled with NF/RO permeate before being placed in a standby mode.

A system and method for the microbiological purification of a liquid. The system includes a high-efficiency plate heat exchanger connected to a coil recirculation chamber via a high-efficiency infrared electric liquid-heater. The liquid enters the system at an ambient temperature, the temperature is raised by the heater and maintained in the chamber via recirculation by a pump. An electronic controller redirects the liquid through the exchanger to cool it and supply to a plumbed outlet. In combination, the system can be used to monitor and control various temperatures, pressures, flow rates, and heat exchanges in order to purify the liquid. The method includes steps to produce, install, implement, and use the liquid purification system to eliminate, neutralize, kill, or otherwise exclude/minimize biological organisms and contamination from the liquid.

A system and method for controlling microbiological growth in a water system and premise plumbing system which uses stabilized hydrogen peroxide as a disinfectant and maintains water energy matrix control. Maintenance of stable hydrogen peroxide residual in the system in combination with active temperature monitoring enables better control of the water energy matrix and reduction of hot water temperature while maintaining microbiological control.

A disinfection system device for producing ozone water directly in a water pipe system contains an electrolytic tap water ozonation generator and holder. The electrolytic tap water ozonation generator includes at least one anode sheet and at least one cathode sheet. The holder includes a base, and the base has a locking portion, an inflow orifice, an outflow orifice, a connection interface, and a damping valve. A flow switch is mounted above the base and has an intake, and a discharge orifice of the flow switch is communicated with the outflow orifice. A top of the base is connected with one of two lids, the other lid is connected with the first socket and a second socket, and the other lid accommodates a control panel. The number of the anode sheet(s) is n which is a natural number and n≥1. The number of the cathode sheets is n+1.

The present invention relates to a water distribution system with hygienisation capacity. According to a first aspect, the present invention describes a water distribution system (I) comprising a water supply, a heating source (IO0) or a point of inflow of externally heated water, at least one sensor measuring water quality, a flow path for water with a user outflow UO, and a control unit for operation of the water distribution system (1), said at least one sensor measuring water quality being connected to the control unit, wherein the water distribution system (I) comprises tubing in a tubing system where at least one portion of the tubing system in the water distribution system (1) comprises a tubing portion which is made of a plastic material comprising silver and/or zinc to provide an inner anti-biofilm of that tubing portion.

A water treatment system centrally communicates and controls one or more water treatment devices to regulate the use of the one or more water treatment devices. The water treatment system is configured to enable a localized, on-demand supply of purified water throughout a building or a network of buildings. The water treatment system may control a degree of purity (e.g., water hardness or concentration of dissolved salts) via mixing of purified and unpurified water streams in a controllable ratio (e.g., via one or more controllable valves or one or more tunable water softening units).

Disclosed are advantageous systems and methods for treating building water systems, especially the interior surfaces of premise plumbing, to remove biofilm and inactivate biofilm-associated pathogens, including protozoa, using disinfectant formulations at concentrations at in excess of those used for drinking water treatment, and further, in co-applying complexing agents to mitigate corrosion of the materials treated; and using these in conjunction with off-gas containment devices that allow flushing of taps without the liberation of toxic fumes.

This disclosure provides techniques for detecting and/or inhibiting corrosion of a distribution/recirculation network for a fluid, e.g., an aqueous matrix (liquid). For example, the disclosed techniques can be used to measure and/or predict degeneration of pipes, solder joints and various other plumbing fixtures in a water distribution network or heat transfer recirculation network caused as a function of variation in environmental parameters. In one embodiment, a system builds a database by measuring metal corrosion (e.g., from lead or copper pipe, solder joint or other type of plumbing vessel or fixture) and correlating degradation of a layer of protective scale and/or metal concentrations present with measured environmental parameters; later, as conditions vary, the database (or associated correlation weights/values) may be used to predict degradation of scale health and/or corrosion stemming from short and/or long term water conditions, and to effectuate advance mitigation.
