Passive water saving and purifying system for making purified water

Abstract

The invention provides a passive water saving and purifying system for making purified water, and belongs to the technical field of water purifying and water saving, and mainly solves the problem thatin the prior art, a massive waste is caused by active purified water making and sewage discharge. The passive water saving and purifying system comprises a prefilter, an ultra-filtration water purifier, a reverse osmosis water purifier, a water heater, an instant direct drinking machine and a toilet. The passive water saving and purifying system is characterized in that an ultra-filtration drainoutlet of the ultra-filtration water purifier is communicated with a water tank of the toilet; an ultra-filtration water outlet is communicated with a kitchen cold water interface, the input end of the water heater, a face washing basin, a cold water interface of a shower, a cold water interface of a washing machine and a water inlet of the reverse osmosis water purifier; a hot water output end ofthe water heater is communicated with a kitchen hot water interface, a face washing basin, a hot water interface of the shower and a hot water interface of the washing machine; a reverse osmosis concentrated water outlet of the reverse osmosis water purifier is communicated with an emergency concentrated water reverse osmosis drain outlet; and a reverse osmosis purified water outlet of the reverse osmosis water purifier is respectively communicated with a purified water storage tank, the instant direct drinking machine and a kitchen direct drinking water interface.

Description

technical field [0001] The invention belongs to the technical field of water purification and water saving, and in particular relates to a passive water-saving water purification system for producing pure water. Background technique [0002] At present, drinking water resources are polluted by various kinds, such as industrial wastewater, pesticide residues, medical waste, industrial and mining heavy metals, etc. This situation threatens our already scarce fresh water resources. We must save water and use science and technology to solve the problem of drinking water safety . [0003] Water purification technology continues to improve, and water purification materials and products are updated and iterated. At present, two mature technologies are commonly used-ultrafiltration purification and (RO) reverse osmosis purification technology. The corresponding equipment is ultrafiltration water purification machine and reverse osmosis water purification machine. , the purification...

AI Technical Summary

Problems solved by technology

However, the waste water discharge of this kind of water purifier is inconvenient to use and store in time, and the problem of waste of water resources is becoming more and more prominent. Although major manufacturers have improved membrane technology and machine water-saving technology, they can only produce one liter At least one liter of concentrated water (RO) must be drained at the same time as pure water. It is very inconvenient to use and store concentrated water. It is especially inconvenient to use concentrated water when installing (RO) water purifiers in houses after decoration. Most Users have to discharge the concentrated water into the sewer pipe for nothing, causing serious waste
