What Is Reverse Osmosis Equipment?
Reverse osmosis is a relatively advanced and energy-efficient membrane separation technology in the world today. It mainly uses the osmosis principle of the semi-permeable membrane, and applies a pressure to it in a certain way, which is opposite to the force of the natural osmosis direction, so that the water in the concentrated solution penetrates into the dilute solution. This method is called reverse osmosis. The device composed of reverse osmosis elements is a reverse osmosis device. Since the pore size of the reverse osmosis membrane is very small, it can effectively remove dissolved salts, colloids, microorganisms, organic substances, etc. in water. The system has the advantages of good water quality, low energy consumption, simple process and easy operation.
Reverse osmosis equipment is suitable for water treatment equipment in food, beverage, chemical, electronic and other industries, and can also be used as core equipment for water purification in communities, industrial areas, and oil fields.
Valves Types Used On Reverse Osmosis Equipment
In this system, it is usually applied to butterfly valves, ball valves, check valves, regulating valves, etc. Different pipelines will have different valve requirements.
● Ball valves, butterfly valves, or gate valves will be used at the water inlet to function as circulation or cut-off
● Control valves, check valves, and hard-sealing butterfly valves are used at the pump outlet
● Shut off valve will be used in the concentrated water pipe and product water pipe
In the above three situations, there will be high-pressure pipelines and low-pressure pipelines, and corrosive media will also be generated. Therefore, it is very important to choose the appropriate valve and valve material. According to the characteristics of reverse osmosis equipment, the valve materials used are mainly duplex steel, nickel aluminum bronze, stainless steel, UPVC, CPVC or PVDF to meet the needs of various media.
Reverse Osmosis System In China
Ball valves, butterfly valves, gate valves and globe valves are shut-off valves. Ball and butterfly valves are quarter-turn valves, while gate valves are linear valves. All three can be used for circulation and cut-off flow, and are used in various types of water supply pipelines.
The check valve is a valve that prevents the backflow of the medium, which is used to protect the normal operation of the system and prevent the pump or motor from being corroded by the backflow of the medium. It helps to increase system uptime and reduce downtime maintenance costs.
Actuator Types Used On Reverse Osmosis Equipment
Today’s manufacturing industry pays attention to production capacity, and in order to increase water production, more and more water treatment equipment will use automatic valves. So how should we choose the right automation actuator?
The electric actuator is driven by current, and can receive and feedback control signals, and is compatible with various control systems, so as to achieve the purpose of remote control of the valve. Pneumatic actuators are driven by gas and need to be equipped with a set of air supply parts, and it is necessary to ensure that the air supply is clean. Pneumatic actuators need to be equipped with positioners to achieve the effect of remote control.
The procurement cost of electric actuators is about twice that of pneumatic actuators. If your budget is limited, then pneumatic actuators will be one of your first choices.
In conclusion, the choice of actuator needs to be based on project requirements and budget. Choosing the right valve for use in reverse osmosis equipment can double your effect and increase your production capacity. If you have any needs for valves, welcome to consult us.
