Reverse osmosis system with magnetic coating

Abstract

The invention provides a reverse osmosis system with a magnetic coating. The system comprises a housing provided with a filtering layer and a water production pipe inside; the filtering layer includes a water incoming channel layer, a film layer, a water producing channel layer, a film layer, a water incoming channel layer sequentially from exterior to interior; the water incoming channel layer is provided with a metal coating provided with an electrode, and the electrode penetrates the housing to be provided with a wiring terminal. The magnetic coating of metal material is adopted, the magnetic field is provided after power is supplied to the coating, partial heavy metal ions and ions affected by the electrode in the water move in an orientated manner instead of acting on the filtering films directly, and the film surfaces are prevented from blocking due to accumulation of ions in the water.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a saline-alkali water treatment osmosis device, in particular to a reverse osmosis system with a magnetic field coating. Background technique [0002] At present, the reverse osmosis system is widely used in water treatment systems. The reverse osmosis membrane in the reverse osmosis system is the core part of water treatment. Using the special structure of the membrane, under a certain pressure, water molecules can pass through Diaphragm, inorganic salts, heavy metal ions, organic matter, colloid, bacteria, salt, etc. in the water cannot pass through the diaphragm, so as to obtain pure water and concentrated water containing a large amount of inorganic salts, heavy metal ions, organic matter, colloid, bacteria, salt, etc., pure The water is used for use, such as drinking, washing, irrigation, and the concentrated water is treated centrally. [0003] However, the problem...

Problems solved by technology

[0003] However, the problem often encountered is that while the diaphragm is blocking inorganic salts, heavy metal ions, organic matter, colloids, bacteria, salt, etc. in the water, these substances that cannot pass through the diaphragm will accumulate on the surface of the diaphragm and accumulate over time, especially in the In saline-alkali areas, the brackish water contains a lot of salt, the membrane is easily blocked, and the water production is greatly reduced, and the replacement of the membrane is a huge expense. How to improve the service life of the membrane, in addition to the water filtration treatment in the early stage , developing a new type of reverse osmosis system is a direction worthy of research
