A kind of water-saving water purifier
Technical field
The present invention relates to a kind of purifier fields, specifically, being to be related to a kind of water-saving water purifier.
Background technology
Water purifier, or also known as water purifier can be used for filtering out floating material, heavy metal, germ etc. in water, for that filter
Except the water purifier of bacterial virus, water outlet can directly be drunk.
At present on water purifier using a plurality of types of filter devices to water quality carry out purified treatment, remove traditional PP cottons,
The filtering materials such as activated carbon, newer filtering material include ultrafiltration membrane and RO reverse osmosis membranes, and both of which can will be in water quality
Bacterium and virus filtration remove, water outlet can directly be drunk, and RO reverse osmosis membranes can more further filter out in water
Heavy metal ion, it is various have several macromolecular substances etc., water belongs to pure water after RO film purified treatments, and water quality is more preferable, and mouthfeel is more preferably.
But require uninterruptedly to rinse film when RO reverse osmosis membrane filtrations, that is, necessarily will produce during water processed a large amount of
Waste water, it is however generally that the ratio of RO water-purifying machine with reverse osmosis membrane output pure water and waste water is 1:2 or 1:3, as soon as a glass pure water is drunk,
The waste water of two glasss or three glasss must be discharged, water resource waste is serious.And if the ratio that pure water and waste water is discharged improved, it rinses
Wastewater flow rate it is insufficient, then can be easy to block RO films, and then scrap, and the cost of RO films is far above other filtering materials, from
And cause to safeguard and reduce waste water, reduce huge opposition between waste, the cost for considerably increasing maintenance and using.
