The water dispensing device of the present invention with the given flow path of water and the control circuit configured store at least two threshold TDS values Xand X, wherein Xis a higher TDS value than X; and to drain water from the treatment unit through the drain line, when TDS value sensed is higher than X, and alternately when the sensed value of TDS is less than Xthen direct water from the reject line into the first recycle line; it was seen that the TDS of the output water of the device was in a constant range and the device of the present invention also contributed to minimizing the wastage of water by allowing recycling of water through the reject line of the treatment unit.

Water dispensing device for dispensing water having consistent taste

The present invention relates to a process and a device for cleaning substrates. In particular the invention relates to an air-water jet device connected to a detergent dosing system. It is therefore an object of the present invention to provide air-water jet device for cleaning fabric articles with enhanced performance; and to provide a dosing device for a detergent composition that may be connected to an air-water jet device. Surprisingly it has been found that a dispensing chamber for a detergent composition DET between the water source and the outlet of the water nozzle provides improved cleaning of an air-water jet.

Process and a device to clean substrates

The present invention is in the field of tooth cleaning devices, especially electrical toothbrushes. The invention further relates to the use of an air/water jet for the cleaning of teeth. A process for cleaning teeth that incorporates a water jet for cleaning teeth remains to be desired, especially a single device that can be employed to clean teeth and reliably deposit material onto teeth. It is therefore an object of the present invention to provide a process for cleaning teeth with an electrical toothbrush device providing improved cleaning by means of an externally mixed air-water jet wherein the water dosing is not influenced by the air pressure. Surprisingly it has been found that a tooth brush device, comprising an air/water jet, wherein the air and water are mixed outside the nozzle(s), provides improved cleaning of dental surfaces, including inter-proximal areas, with low usage of water.

Process for cleaning teeth

The present invention is in the field of household cleaning tools. The invention further relates to the use of an air-water jet for the cleaning of hardsurfaces. It is an object of the present invention to provide easier cleaning of hard surfaces. It is therefore an object of the present invention to provide a process of easier cleaning of hard surfaces, especially by means of a device that uses a relatively low water flow rate. Surprisingly it has been found that an external mix air-water jet device may be used for cleaning hard surfaces.

Process for cleaning hard surfaces

In particular a porous substrate (FS) like a fabric. Process to clean a substrate, comprising a step of subjecting the substrate to an air-water spray (SPR), generated using a spraying means (N) comprising an air passage (OPA) and a water passage (OPW), wherein air is greater than 90% by volume of the spray, the air velocity is greater than 80 m/s and wherein said air passage does not coaxially surround said water passage. Device to clean soiled fabric (FS) comprising a feed water container (CW) and an air compressor (AC) in fluid communication with a spray nozzle (N) comprising an air passage and a water passage, said device being capable of generating an air pressure in the range of 1 to 3 bar (absolute) and an air velocity greater than 80 m/s at the exit of said nozzle; and the air is greater than 90% volume of said spray, and wherein said air passage does not coaxially surround said water passage. An external mix spray nozzle is especially preferred in the device.
