Reverse osmosis pure water machine treatment system

Abstract

The invention discloses a reverse osmosis pure water machine treatment system, which comprises a system water inlet, a pre-filtration unit, an RO membrane filtration unit and a system water outlet, wherein the RO membrane filtration unit comprises a first-stage RO filtering core and a second-stage RO filtering core, the first-stage RO filtering core has a first-stage raw water inlet, a first-stagepure water outlet and a first-stage concentrated water outlet, the second-stage RO filtering core has a second-stage raw water inlet, a second-stage pure water outlet and a second-stage concentratedwater outlet, a raw water inlet channel is connected between the first-stage raw water inlet and the system water inlet, a pure water outlet channel is connected between the first-stage pure water outlet and the system water outlet, the first-stage concentrated water outlet is communicated to the second-stage raw water inlet through a first-stage concentrated water discharge channel, the second-stage pure water outlet is communicated to the pure water outlet channel, and the second-stage concentrated water outlet is connected to a second-stage concentrated water discharge channel. With the reverse osmosis pure water machine treatment system of the present invention, the concentrated water can be effectively utilized, the discharge of the concentrated wastewater can be reduced, and the water production cost can be reduced.

Description

technical field [0001] The invention relates to the field of water purification systems, in particular to a reverse osmosis pure water treatment system. Background technique [0002] With the increasingly serious water pollution and the improvement of people's living standards, people pay more and more attention to health, and the requirements for drinking water are also getting higher and higher. As a result, various water purification products have gradually entered homes, offices, factories and other places. The existing water purification products mainly include reverse osmosis type and absorption type. Currently, reverse osmosis type water purification products are more widely used. [0003] In reverse osmosis water purification products, the raw water will produce pure water and concentrated water after being treated by the reverse osmosis water purification system. The ratio of pure water to waste water in the existing reverse osmosis pure water treatment system is ab...

AI Technical Summary

Problems solved by technology

[0003] In reverse osmosis water purification products, the raw water will produce pure water and concentrated water after being treated by the reverse osmosis water purification system. The ratio of pure water to waste water in the existing reverse osmosis pure water treatment system is about 1:1. The utilization rate is about 50%. At present, the water treatment system of some water purification products adopts the method of returning concentrated water, which can improve the utilization rate of raw water, but the utilization rate is still low. Today, when water resources are increasingly scarce, the concentrated water Simple discharge is obviously still very wasteful. Due to the low utilization rate of raw water in existing pure water machines, the cost of water production is relatively high, and water resources are seriously wasted, which limits its further promotion and application in the market.
