Description

Reverse osmosis device

Technical Field

The utility model relates to the field of water treatment, in particular to a reverse osmosis device for water treatment.

Background

The natural flow of water through a semi-permeable membrane into a solution or from a dilute solution to a more concentrated solution is called osmosis. Such membranes having selective permeability to water or solutions are referred to as semi-permeable membranes. However, the permeation can be stopped by applying an appropriate pressure to the concentrated solution side, and the pressure at which the permeation of the dilute solution into the concentrated solution is stopped is referred to as the osmotic pressure. Reverse osmosis is the process of applying a higher pressure to one side of the concentrate than the natural osmotic pressure, reversing the natural osmotic direction, and forcing the water in the concentrate to the other side of the semi-permeable membrane, as opposed to the normal osmotic process in nature, and is therefore called reverse osmosis. Such a tailored semi-permeable membrane is called a reverse osmosis membrane.

Reverse osmosis is an advanced membrane separation technology. This technique involves passing certain components of the solution to be separated (e.g., water in seawater) under pressure through a semi-permeable membrane, a reverse osmosis membrane, which is a selectively permeable membrane, and collecting the permeate on the low pressure side of the membrane, while leaving a concentrated solution of the other components on the high pressure side of the membrane. It is a high and new technology with energy saving, high efficiency, no pollution and strong practicability.

However, the existing reverse osmosis device can cause blockage after being used for a period of time, and if the problem cannot be solved timely and effectively, the subsequent purified water yield can be influenced to a great extent.
