Secondary Reverse Osmosis Precision Filtration Reduces Salinity and Explosion-proof Water Filtration Equipment

Product description

Secondary reverse osmosis precision filtration reduces salt content
Working principle
Primary reverse osmosis: Under the action of a high-pressure pump, the raw water passes through a reverse osmosis membrane, and most of the dissolved salts, bacteria, viruses, organic matter and other impurities are intercepted, producing water that is initially purified and has reduced salt content. Reverse osmosis membranes have semi permeability, allowing only water molecules to pass through and blocking other substances.
Secondary reverse osmosis: The water produced by primary reverse osmosis is used as the inlet for secondary reverse osmosis and then filtered through a reverse osmosis membrane. Further remove a small amount of residual salt and other impurities from the water, resulting in lower salt content in the produced water and higher water purity. Through two-stage reverse osmosis, the salt content in water can be effectively reduced to meet the demand for high-purity water, such as in industries with extremely high water quality requirements such as electronic chip manufacturing and pharmaceuticals.
Key components
Reverse osmosis membrane element: It is the core of the reverse osmosis system, usually adopting a roll structure, with high desalination rate and water flux. Different brands and models of reverse osmosis membranes have differences in desalination performance, service life, and anti pollution ability.
High pressure pump: provides the necessary pressure for water to pass through the reverse osmosis membrane, and its performance directly affects the system’s water production and desalination efficiency. Suitable high-pressure pumps need to be selected based on the scale and requirements of the system.
Control system: Using PLC (Programmable Logic Controller) and human-machine interface, real-time monitoring of system parameters such as pressure, flow rate, water quality (such as conductivity, TDS, etc.), and automatic adjustment of system operation according to the set program, such as automatic flushing of reverse osmosis membrane to prevent membrane fouling and ensure stable system operation.
Explosion proof water filtration equipment
Explosion proof principle
The electrical components of the equipment (such as motors, controllers, etc.) adopt explosion-proof design, such as using explosion-proof structures, intrinsic safety structures, etc. Explosion proof type is to enclose the live parts of electrical equipment in a sturdy enclosure. When an explosion occurs inside the enclosure, the explosion pressure will not be transmitted to the outside of the enclosure; Intrinsic safety is achieved by limiting the energy of electrical equipment circuits, so that the sparks and heat generated under normal and fault conditions are insufficient to ignite the surrounding combustible gases or dust.
The structure and material selection of the equipment also consider explosion-proof requirements, such as using explosion-proof enclosures, explosion-proof junction boxes, etc., to prevent explosion hazards caused by sparks, heat, etc. generated during equipment operation.
Application scenarios
Petrochemical industry: In the processes of petroleum refining and chemical production, it is necessary to treat water containing salt and other impurities. At the same time, due to the presence of flammable and explosive gases and dust in the production environment, explosion-proof water filtration equipment can ensure effective filtration of water under the premise of safety, meeting the demand for production water.
Natural gas extraction and processing: During the extraction and processing of natural gas, a large amount of saline water is generated. Explosion proof water filtration equipment can be used to treat these saline water, reduce salt content and meet emission standards or reuse requirements, while ensuring the safe operation of equipment in hazardous environments.
Coal mining industry: There are flammable and explosive gases such as gas in the underground environment of coal mines. Explosion proof water filtration equipment can be used to treat mine water, remove salt and impurities, provide clean water sources for mine production, and prevent explosion hazards caused by equipment operation.

This water filtration equipment, which combines secondary reverse osmosis precision filtration to reduce salt content and explosion-proof function, can effectively treat salt and impurities in water and operate safely in environments with explosive hazards, and has important application value.
