摘要
The present invention relates to a gravity fed water purification device having controlled dosing of liquid biocide for providing safe and hygienic water for potable purposes. It is an object of the present invention to provide for a system for dispensing liquid biocide solutions in to water to be purified in a gravity fed water purification device, especially a device that provides large dilution ratio consistently over long time, without any electrically controlled devices. The invention provides a gravity-fed water purification device comprising a biocide dosing passagecomprising a venturianda by-pass passage wherein the cross- sectional area of said by-pass passage is greater than the cross-sectional area of the constricted zone of the venturi.
