500LPH Drinking Water Reverse Osmosis One Stage water treatment plant

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).

Dringking water RO system preprocessing requirements:

1. The reverse osmosis pretreatment must be able to remove most of the impurities in the raw water to meet the water inlet requirements;
2. Reverse osmosis pretreatment must consider changes in water quality to prevent fluctuations in raw water quality from affecting the stable operation of the entire system;
3. The reverse osmosis pretreatment process must be able to operate efficiently and stably, while simplifying the process as much as possible to reduce investment and operating costs

Characteristics of RO Water Treatment System

 

Compared with other water treatment methods, it has the advantages of no phase change, normal temperature operation, simple equipment, high efficiency, less occupation, convenient operation, less energy consumption, wide range of adaptation, high degree of automation and good effluent quality. Reverse osmosis desalination rate and purity of produced water are higher than electrodialysis, for high fluoride and low salinity brackish water desalination by reverse osmosis, effluent water quality can reach our daily drinking purified water health standards. And reverse osmosis desalination brackish water energy consumption - - electricity consumption, water consumption are lower than electrodialysis, and reverse osmosis equipment compact structure, small footprint, stable and reliable operation effect, in line with the "clean production" requirements, reverse osmosis is more reasonable than other methods, effective desalination brackish water method.

 

Ro water treatment system method is used to desalinate brackish water with different salt content. The desalting rate of the system is above 96 %, and the quality of desalted water reaches the standard of drinking water. The brackish water desalination device of reverse osmosis system has strong adaptability. It can realize continuous treatment of brackish water with different salt content by adjusting operation parameters according to the quality of raw water. The device is highly integrated and is expected to become a complete set of finalized equipment.

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.

Composition of RO Water Treatment System

 

Reverse osmosis purified water treatment system generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system.

 

1, the pretreatment system generally includes the original water pump, dosing device, quartz sand filter, activated carbon filter, precision filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine to meet the requirements of reverse osmosis inlet water.

2. Reverse osmosis device mainly consists of multistage high pressure pump, reverse osmosis membrane element, membrane shell (pressure vessel), bracket and so on. Its main function is to remove impurities in water, so that the water meets the requirements of use.

3. Post-treatment system is an additional configuration in the case that reverse osmosis cannot meet the requirements of outlet water. Mainly including negative bed, positive bed, mixed bed, sterilization, ultrafiltration and other one or more of the equipment.

4, cleaning system is mainly composed of cleaning water tank, cleaning water pump, precision filter. When the reverse osmosis system is polluted and the effluent index cannot meet the requirements, it is necessary to clean the reverse osmosis system to restore its efficacy.

5. Electrical control system is used to control the normal operation of the whole reverse osmosis system. Including instrument panel, control panel, all kinds of electrical protection, electrical control cabinet, etc.
