Conventional reverse osmosis water treatment system process is: raw water → pretreatment system → high-pressure pump → reverse osmosis membrane assembly → purified water.

The pretreatment system according to the condition of raw water quality and water requirements Can take the coarse filter, activated carbon adsorption, fine filtration, precision filtration is necessary, in order to protect the reverse osmosis membrane, prolong the service life of, in addition, the composite film is sensitive to the free chlorine in the water, and thus are usually equipped with activated carbon adsorption pretreatment system.

What size unit of RO Water Treatment System do I need to purchase?

For different types of water, the limits of osmotic flux and elemental recovery in ro water treatment system are based on the correlation between SDI value and membrane contamination and the correlation between mineral content and elemental recovery respectively. For example, systems designed to have high permeability flux rates may experience higher scaling rates and more frequent chemical cleaning. The design of seawater systems is further limited by osmotic pressure and durability of membrane elements due to high salinity (> 36,000 PPM TDS).

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.

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.
