500LPH Dringking Water RO System One-Stage RO System SUS304 For Pure Water

The working principle of drinking water ro system membrane:

A membrane that is selective for permeable substances is called a semi-permeable membrane, and a membrane that can only permeate a solvent but cannot permeate a solute is generally called an ideal semi-permeable membrane. When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water) are placed on both sides of the semipermeable membrane, the solvent in the dilute solution will naturally pass through the semipermeable membrane and flow to the concentrated solution side spontaneously, This phenomenon is called penetration. When the osmosis reaches equilibrium, the liquid level on the side of the concentrated solution will be higher than the liquid level of the dilute solution by a certain height, that is, a pressure difference is formed, and this pressure difference is the osmotic pressure (see the figure for the working principle of the reverse osmosis membrane).

Types of Drinking Water RO System

1. Cellulose acetate RO membrane. Cellulose acetate is also called acetyl cellulose or cellulose acetate. Cellulose-containing cotton, wood, etc. are often used as raw materials, and are made into cellulose acetate through esterification and hydrolysis, and then processed into reverse osmosis membranes.
2. Composite RO membrane. The characteristic of the composite RO membrane is that it is mainly made of the above two materials, which is composed of a thin dense layer and a porous support layer. The porous support layer, also known as the base film, plays the role of enhancing the mechanical strength. The dense layer is also called the epidermis layer, which plays the role of desalination, so it is also called the desalination layer. The thickness of the desalination layer is generally 50nm, and the thinnest is 30nm.
3. Polyamide RO membrane. Polyamides include aliphatic polyamides and aromatic polyamides. The main applications in the 1970s were aliphatic polyamides such as nylon-4, nylon-6 and nylon-66 membranes.

FAQ:

1. What is the membrane material of drinking water reverse osmosis system?

Acetate membrane (CA) : mainly because of its resistance to chlorine, so it is still durable. But its suitable pH range is small, easy hydrolysis

Aromatic polyamide membrane (PA) : water almost can not have chlorine, only through a variety of pretreatment chlorine.

2. What is the material of mechanical filter?

Carbon steel, stainless steel, fiberglass

3, multi-way control valve according to the control mode of those?

Manual control valve, automatic control valve

Multi - way control valve is divided into: filter valve and softening valve

Automatic control valve is divided into: time type and flow type.

Multi-way control valve brands are: FLECK, AUTOTROL, Runxin, clean source, etc.
