Composite foam membrane water purification system

Abstract

The invention provides a composite foam membrane water purification system, which comprises: a filtering core group, wherein the filtering core group comprises a fore-lying filtering core and a reverse osmosis filtering core, and the filtering core group is provided with a raw water inlet and a purified water outlet communicated with the fore-lying filtering core, and is also provided with a purified water inlet, a wastewater outlet and a purified water outlet communicated with the reverse osmosis filtering core; and a foam membrane filtering part, wherein the foam membrane filtering part comprises a filtering bottle, a first water inlet, a first water outlet and a stored water inlet and outlet are formed in the filtering bottle, a soft water tank body is arranged in the filtering bottle,a rear-lying filtering core is arranged in the soft water tank body, the water inlet end of the rear-lying filtering core is communicated with the first water inlet, the water outlet end of the rear-lying filtering core is communicated with the first water outlet, and a water storage space communicated with the stored water inlet and outlet is formed between the outer side of the water tank body and the inner side of the filtering bottle. According to the invention, by arranging and applying the water purification system, the TDS value of the first cup of water obtained by restarting after thewater purification system is standby can be reduced.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a composite bubble film water purification system. Background technique [0002] At present, the existing household large-flux RO / NF pure water machines are conventionally rated as 400G, 500G, 600G and other models. Since the core components used in reverse osmosis and nanofiltration water purification are semi-permeable membranes, the water purifiers During standby, the TDS value of the water staying on the raw water side is higher than that of the water staying on the pure water side, so that the salt content of the water on the raw water side can easily penetrate into the water on the pure water side, which will eventually make the semi-permeable membrane on the raw water side and The water salinity concentration on both sides of the pure water side is basically the same. As a result, whenever the water purifier is on standby for a period of time, the TDS value of th...

Problems solved by technology

As a result, whenever the water purifier is on standby for a period of time, the first cup of water that the user receives has a high TDS value, and the water quality cannot meet the filtration requirements.
