The Application of Industrial Reverse Osmosis Systems in Automotive Manufacturing

What wastewater is generated in the automotive industry production?

The production processes in the automotive industry mainly include machining, forming, welding, surface treatment, painting, and final assembly. Surface treatment and painting are the main processes that generate wastewater. The wastewater mainly contains surfactants, oils, phosphates, metal salts, organic solvents discharged from surface treatment and painting processes, as well as high-concentration emulsions discharged from machining.

What are the methods for treating wastewater in the automotive industry?

Currently, the main methods for treating wastewater in the automotive industry include biological treatment, physicochemical treatment, and membrane separation. Our industrial reverse osmosis technology provides a feasible solution for treating wastewater in car manufacturing plants.

How can Amanda's industrial reverse osmosis systems help?

Our industrial reverse osmosis systems have been used in car manufacturing, with customers choosing the BW30-400-FR reverse osmosis membrane, with a total of 10 membranes, each with a water production capacity of 1.0 t/h, operating pressure of 1.2-1.5 MPa, made of aromatic polyamide (PA), and the membrane shell made of SUS304. There is one set of racks, made of Q235A. Under pressure, water passes through highly selective reverse osmosis membranes, separating inorganic salts, organic compounds, hardness ions, bacteria, and other impurities from water, with a removal rate of 98%-99%. The water production rate of the reverse osmosis system is 50%.

Application and advantages of industrial reverse osmosis systems in the automotive manufacturing industry.

The use of large-scale industrial reverse osmosis systems in the automotive manufacturing industry significantly reduces reliance on freshwater resources. By treating and reusing water, these systems help conserve water and reduce the industrial impact on local water resources. Furthermore, efficient removal of pollutants from wastewater helps minimize the discharge of harmful substances into the environment, protecting ecosystems and public health.

Water treatment and purification:
Water plays a critical role in various stages of automotive manufacturing, including surface treatment, painting, cooling, and cleaning. Industrial reverse osmosis systems effectively remove impurities, pollutants, and dissolved solids from water, ensuring a stable supply of high-quality water for these processes. By achieving high levels of water purification, RO systems contribute to improving the overall quality and durability of automotive components.

Paint shop operations:
The paint shop is a crucial area in automotive manufacturing, where paint quality directly affects the appearance and lifespan of vehicles. Reverse osmosis systems play a vital role in providing pure water for paint mixing and spraying processes. By removing impurities and minerals from water, the risk of paint defects caused by particles or chemical reactions can be eliminated, resulting in a consistent and flawless paint finish.

Cooling systems:
Automotive manufacturing involves various cooling processes, such as cooling engines and hydraulic systems. Reverse osmosis systems ensure a reliable and clean water source for these cooling systems. By removing impurities and minerals, RO-treated water prevents scaling, corrosion, and blockage in cooling pipelines and components. This helps maintain optimal cooling efficiency, prolong equipment lifespan, and reduce maintenance costs.

Wastewater treatment:
Like any manufacturing process, automotive production generates wastewater that needs to be treated to meet environmental standards. Industrial reverse osmosis systems can be integrated with wastewater treatment equipment to purify and recycle water, minimizing water consumption and reducing pollutant discharge. This sustainable approach not only helps protect water resources but also contributes to the overall environmental sustainability of the automotive manufacturing industry.
