Seawater purification and water treatment equipment application
Seawater purification equipment
• Technical principle:
• Reverse osmosis: By applying high pressure, water molecules in seawater pass through the semipermeable membrane to remove dissolved substances such as salt
Reverse osmosis technology has the advantages of high desalination rate and relatively low energy consumption
• Distillation: Including multi-stage flash evaporation and multi-effect distillation, using heating to evaporate seawater and then condensing the steam into fresh water
Distillation is suitable for energy-rich areas
• Electrodialysis: Through the action of the electric field, the ions in the water are separated through the ion exchange membrane to achieve the purpose of desalination of seawater
• Application scenarios:
• Drinking water supply: In areas with scarce freshwater resources such as islands and deserts, seawater purification equipment can provide stable drinking water
• Industrial water: Provide high-purity water required by the chemical, electronic, pharmaceutical and other industries
• Agricultural irrigation: Desalinated seawater can be used for agricultural irrigation to increase crop yields
Water treatment equipment
• Technical principle:
• Reverse osmosis technology: Use semipermeable membranes to remove dissolved salts, heavy metals, organic pollutants, etc. in water
• Ultrafiltration and nanofiltration technology: remove suspended matter, microorganisms, some organic matter and high-valent ions in water through membrane materials with different pore sizes
• Activated carbon filtration: use the adsorption characteristics of activated carbon to remove organic matter, odor and some heavy metals in water
• Application scenarios:
• Drinking water purification: widely used in drinking water treatment in homes and public places to ensure water quality safety
• Industrial wastewater treatment: in chemical, electronic, pharmaceutical and other industries, used to treat industrial wastewater, recover useful components and reduce environmental pollution
• Municipal sewage treatment: used in urban sewage treatment plants to treat domestic sewage and some industrial wastewater, and improve the reuse rate of water resources
• Agricultural irrigation: purified water can be used for agricultural irrigation to improve the utilization efficiency of water resources
• Swimming pools and spas: keep the water clear and sanitary, and provide a safe and comfortable swimming environment
Seawater purification and water treatment equipment play an important role in solving water shortages, improving water quality and protecting the environment, and have broad application prospects.
