RO water treatment system introduction
RO water treatment system is an advanced water purification technology that uses semi-osmosis membrane (RO membrane) to eliminate water-soluble substances such as salt, bacteria, virus and other impurities. When working, the water is higher than its natural osmosis pressure, pushed by high pressure pump, then forced to pass through RO membrane; ultra-small aperture membrane, only allows water molecules to pass through, While preventing most contaminants going through. This process is called reverse osmosis. RO system usually includes important parts such as pre-treatment, diaphragm separation, high-pressure pump and rear treatment. Its output water is of high quality, can meet the strict water quality standards and often used in areas such as drinking water, pharmaceutical, lab and industrial water. Although creating part of the sewage contains concentrated pollution, high efficiency of filtration and relatively low energy consumption makes it one of the essential technology for water management and preservation.

 
RO water treatment system
Reverse osmosis equipment usually includes pretreatment device (quartz sand filter, activated carbon filter, precision filter), softener (if needed), booster pump, high pressure pump, membrane shell, reverse osmosis membrane element, Spot tools, quantitative system, full-automatic control system, rack platform, etc.
1. Pre-treatment system: normally including steps such as filtration, softener or throwing chemical to eliminate suspension, chlorine, organic agent and prevents film scale.
2. high pressure pump: increase the water pressure to that much to exceed the osmosis pressure, so that the water molecules go back through RO membrane.
Ro film component: core component, only allow the water molecules to pass through, and prevent most salt from soluble, bacteria and electrolytes going through.
4. Flow Controller: regulating the flow speed of concentrated water production and water, ensure the operation efficiency of the system.
5. The following storage and treatment system: containing water tank and the following treatment equipment can be, such as ultraviolet ray sterilization or carbon filtration, etc. V. T.


RO water treatment system features
1. high efficient decontamination ability: can eliminate a variety of contaminants, including soluble salt, granular, bacteria and Endogen.
2. High quality water output: RO treated water can reach very purified water, suitable for many uses, including drinking and industrial water.
3. low energy consumption: compared to other separation process, RO system requires relatively low energy during operation.
4. high automation level: modern RO system can achieve high automation control, reduce the need for manual operation and defect rate.
5. Few sewage produced: though a certain thick amount of water will be produced, the acceptable amount of sewage is related to its ability and efficiency.

 
Water treatment system ro application area
1. sea water purification: due to the high efficiency of salt filtration, RO technology has taken an important place in the global salt filtration sector. With this technique, the soluble salt in the water can be removed and the sea water can be converted to drinking fresh water.
2. Industrial purified water preparation: in the industrial production process requires high purity water quality, such as electronic ultrapure water preparation, RO technology also play a very important role. It can ensure the water quality used during the production process meets the strict standards.
Reuse sewage: for urban and industrial sewage, RO technology is also suitable, it can help to reduce the environmental pollution and improve the water resources recycling rate.
4. Household water purification: about home water, RO technology can eliminate organic substances, colloids, micro-creatures and other small particles in the water, keep your drink safe and hygienic in the house.
In addition, RO technology can be used in agricultural irrigation, in the food and beverage industry and in the pharmaceutical industry for water quality treatment.

Technical principle of

Ro Ro water treatment system is a method of using semi-automatic membrane technology for the application of water purification based on the principle of osmosis phenomenon and osmosis pressure of yes of solution. In a natural condition, water molecules absorb semi-seepage from low concentration solution to high concentration solution, A process is to reduce the difference of concentration between the two sides until balancing is achieved. Ro is a artificial reverse of this process, which means by applying higher pressure than the external osmosis pressure, tying water molecules from high-concentration solution to low-concentration solution, thereby reaching the purpose of purification.


In RO water treatment system, rough water after pre-treated to eliminate suspension, chlorine and some organic substances, filled with high pressure which is higher than its osmosis pressure. High pressure water is then sent to RO membrane element with micro aperture and select transmission ability, only allows water molecules to pass through and prevent majority of soluble substances such as salt and bacteria. Therefore, when water contact RO membrane, the water molecules enter back through the membrane under the action of pressure to the pure water, while the solubility are trapped at the rough water side, producing two parts of the water flow: One side is pure water (water production) that removes contaminants and the other side is sewage (concentrated water) that contain concentrated pollution.


RO membrane is the core of the whole system and its performance affect directly the separation efficiency and operation efficiency of the system. Film selection must consider the listed ability, water flux, and its anti-pollution to different electrolytes. To maintain ro performance and extend life, the system should be regularly washed in physical or chemical to eliminate accumulated dirt and grow of creatures.

Frequently Asked Questions

Q: What is the primary purpose of RO system?
Re: the RO system is mainly used to eliminate water-soluble solid substances (such as salt, minerals), bacteria, virus, heavy metal and other impurities, provide high purity of water, suitable for filtration of drinking water, Pharmaceutical production, laboratory water, waste water treatment and other areas.


Q: How about different water quality treatment RO system?
Re: the RO system adapt to different water source scenarios and water quality by adjusting the treatment steps, such as increase the hardness of the softener to eliminate organic substances, use activated carbon filtration to eliminate organic substances, Etc.;


Q: Why does RO system create sewage?
Re: In the RO process, part of water was pressed through the membrane while other part was not, water did not pass by the higher pollution content, this part of water is called dark water or sewage.


Q: How about the filtration rate of RO system?
Re: the salt filtration rate refers to the percentage of salt that is removed in total salt in rough water, which is usually calculated by conductive measurement, as stated in: (1-(water conductivity/water conductivity) × 100%.


Q: How to clean and maintain RO membrane?
Re: RO membrane should be washed regularly to eliminate sedimentation and biological dirt. Cleaning methods include physical cleaning (such as Splash or circulation washing) and chemical cleaning (specific detergents use).


Q: What are the common problems of RO system operation?
Re: Common problems include film pollution, film Damage, system pressure loss, reduce water permeability and lower waste water quality, etc.


Q: How about the energy consumption of RO system?
Re: the energy consumption of the RO system mostly depends on the water pressure and flow that is needed, as well as the pump efficiency in the system. High-pressure pump is the biggest energy consumption, but Ro is generally a relatively energy-saving water treatment technology.


Q: How long life of RO system?
Re: the life of RO system is affected by many factors, such as water quality, operating conditions, maintenance and maintenance. Usually RO membrane may need to be replaced within 3 to 5 years, but the whole system can be designed to last longer and properly maintained which can exceptionally extend service time.
