A water treatment apparatus management system which manages a household water treatment apparatus located at or near a place of water use, and treats water before treatment with at least one type of filter to produce treated water for the place of water use. The system includes: a filter information storage unit storing information regarding an in-service filter used in the household water treatment apparatus; an information receiver receiving information regarding performance change of the in-service filter from the household water treatment apparatus; and a water type estimation means that estimates a water type of the water before treatment based on the information regarding performance change and the information regarding the in-service filter. The information regarding the in-service filter includes reference information of performance change of the same or the same type of filter as the in-service filter for each of plural types of reference water before treatment.

Disclosed herein is a refrigerator, and more particularly, to a refrigerator including a water supply system. The refrigerator includes a main body including a storage compartment, and a water supply assembly disposed in the storage compartment. The water supply assembly includes a first filter mounting portion provided to allow a first filter to be mounted thereon, and a second filter mounting portion provided to allow a second filter to be mounted thereon, and including a residual water guide configured to guide residual water in the second filter mounting portion to the first filter mounting portion.

The invention relates to a bioactive filter for the disinfection of liquids, in particular water or aqueous solutions in containers. A structure that is advantageous in terms of filter efficiency is obtained by forming a spherical or oval filter body (1), which is coated with noble metals (FIG. 1).

The present disclosure relates to an automatic control system and method for water treatment of a thermal sterilization kettle. The system comprises a sampling module, a monitoring module and a control module, wherein the sampling module is used for respectively sampling hot water and cold water, and the monitoring module is arranged to respectively monitor online fluorescence signals in the sampled hot water and the sampled cold water; the control module is used for respectively controlling whether to add a compound medicament into a hot water area or not according to the online fluorescence signal of the sampled hot water and controlling whether to add the compound medicament into a cold water area or not according to the online fluorescence signal of the sampled cold water; and meanwhile, the monitoring module is further used for monitoring the residual chlorine signal of the sampled cold water.

A household dishwasher includes a washing container for holding a dishwasher load, a sump arranged at a bottom of the washing container, a filter system provided at the sump, and a spray arm for applying washing liquor and/or fresh water to the dishwasher load. The spray arm includes an extension piece which is mounted on the sump for rotation about a first axis of rotation and includes a filter cleaning nozzle for cleaning the filter system with the aid of the washing liquor and/or fresh water, and a spray arm satellite which is mounted on the extension piece for rotation about a second axis of rotation.

A tankless water heater including a water inlet, a water outlet, a conductivity sensor, a temperature sensor, and a heating chamber connected to the water inlet and the water outlet wherein the heating chamber is configured to heat a flow of water received from the water inlet and output the flow of water to the water outlet. The water heating system can further include a controller communicably coupled to the conductivity sensor and the temperature sensor, where the controller calculates an adjusted conductivity of a flow of water through the water heater.
