Abstract

A method for liquid purification, comprising the following steps: acquiring the TDS value of concentrated water; and if the TDS value of the concentrated water is less than a set threshold, then returning the concentrated water into a raw water channel for re-filtration. Also provided is a system for liquid purification, comprising an acquisition unit (201) and a release unit (202).

Description

Liquid purification method and system

Technical field

The invention relates to the field of purification, and in particular to a liquid purification method and system.

Background technique

The water purifier is also called water purifier and water filter. The core of the technology is the filter membrane in the filter unit. The main technology of the water purifier comes from the ultrafiltration membrane and the RO reverse osmosis membrane. Small water treatment equipment for deep purification of water quality. The water purifiers usually mentioned are generally used as small filters for home use.

Existing water purification is a serious waste of water.

technical problem

The application provides a liquid purification method. It solves the shortcomings of serious waste of water source in the technical solutions of the prior art.

Technical solution

In one aspect, a liquid purification method is provided, the method comprising the steps of:

Obtaining the TDS value of concentrated water;

If the TDS value of the concentrated water is lower than the set threshold, the concentrated water is returned to the raw water channel for filtration again.

Optionally, the method further includes:

If the TDS value of the concentrated water is higher than the set threshold, the concentrated water is discharged.

Optionally, the method further includes:

Record the number of discharges of concentrated water and the discharge time.

In a second aspect, a liquid purification system is provided, the system comprising:

Obtaining unit for obtaining a TDS value of concentrated water;

The playback unit is configured to return the concentrated water to the raw water channel and filter again if the TDS value of the concentrated water is lower than the set threshold.

Optionally, the system further includes:

The discharge unit is configured to discharge concentrated water if the TDS value of the concentrated water is higher than a set threshold.

Optionally, the system further includes:

A recording unit for recording the number of discharges of concentrated water and the discharge time.

Beneficial effect

The technical solution provided by the invention obtains the TDS value of the concentrated water. If the TDS value of the concentrated water is lower than the set threshold, the concentrated water is returned to the raw water channel for filtration again, so that it has the advantage of water saving.
