The water treatment industry plays a crucial role in safeguarding public health, protecting the ecological environment, and promoting resource recycling. From wastewater treatment to drinking water purification and seawater desalination, hoses are an essential component in all aspects of water treatment. Hoses are not only necessary for transporting water, chemicals, and wastewater, but also play an irreplaceable role in ensuring the efficient and stable operation of water treatment systems.

Wastewater treatment is one of the primary areas where hoses are used. Wastewater often contains harmful substances or corrosive chemicals, requiring hoses with high resistance to corrosion and chemical degradation. In this process, hoses are used to transport polluted water, chemicals, and additives, ensuring the smooth operation of the wastewater treatment process. PVC hoses, due to their excellent resistance to corrosion and chemical erosion, are widely used in wastewater treatment systems, reducing the risks of hose aging or leakage and extending their service life.

For drinking water treatment, hose requirements are even stricter. The hoses used must guarantee the safety of the water and contain no harmful substances to humans. Additionally, hoses for drinking water treatment typically need to have antibacterial properties to ensure the water's hygiene. In this field, food-grade PVC hoses are widely applied. These hoses not only meet sanitary standards and ensure water safety but also possess good antibacterial properties, preventing water source contamination and making them easy to clean and disinfect, further ensuring the safety of drinking water.

The application of hoses in seawater desalination systems is also significant. Seawater desalination is an important technology for addressing water resource shortages, and hoses are used to transport seawater, desalinated water, and chemicals during the process. Since seawater contains a large amount of salt, hoses used in this process need to have strong resistance to salt corrosion and high pressure. Choosing the right hose material is crucial for the stable operation of seawater desalination systems, and this is a major challenge in hose design.

The material of the hose directly affects its performance in water treatment. Choosing the right material not only improves the hose's durability but also ensures the safety of the water. Common hose materials used in water treatment include PVC, silicone, rubber, and polyethylene (PE). PVC hoses are the most commonly used and offer strong corrosion resistance, chemical erosion resistance, and long service life. For certain specific water treatment processes, silicone hoses are widely used due to their excellent temperature adaptability and non-toxicity. They can withstand temperatures ranging from -50°C to 200°C, making them ideal for high-temperature environments. In addition, rubber hoses are often used in wastewater treatment and industrial water treatment systems that require high-pressure resistance, while PE hoses are widely used in low-pressure water treatment systems due to their excellent resistance to corrosion and abrasion.
