Water system capable of solving problem of first cup of water

Abstract

The invention discloses a water system capable of solving the problem of first cup of water, and is used for solving the problem of high TDS content in the first cup of water of an RO filter element in the existing water purification. The water system comprises a water purification pipeline, a filter pipeline and a wastewater discharge pipeline; a purified water opening is formed in one end of the purified water pipeline, a pure water opening is formed in the other end of the purified water pipeline, and a front filter element, a second water inlet valve, a booster pump, an RO filter element, a check valve and a high-pressure switch are sequentially installed on the purified water pipeline; after tap water is filtered by the front filter element, one path is added to be connected with the resin filter element, the tap water is filtered by the resin filter element and then reaches the RO filter element, after the RO membrane in the RO filter element finishes working, the second water purification valve is closed, the first water inlet valve is opened, the waste water valve is opened at the same time, the tap water passes through resin, the TDS of purified water is reduced by utilizing the ion adsorption function of the resin, and the ion concentration before RO is reduced; the problem of forward osmosis of RO is solved, so that the problem of high TDS of first cup of water of the RO filter element is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water system capable of solving the problem of the first glass of water. Background technique [0002] The tap water for daily drinking has gone through a variety of cleaning, sterilization and disinfection methods, and the water quality test at the factory can meet the national hygiene standards, and then flows into thousands of households through long pipelines and secondary pressurized water tanks. Before flowing into households, long pipelines have passed through complex terrain and roads. Some pipelines have been in disrepair for a long time, and some water pipes intersect with sewage pipes. Some water pipes in the building even have to go through the toilet before reaching the kitchen, so the water needs to be purified. Existing water purification has the problem of high TDS content in the first glass of water of the RO filter element. Contents of the invention ...
