ملخص المقالة :
با توجه به بحران جهانی آب، تصفیه و باز استفاده از پسابهای صنعتی بهویژه در صنایع آببر مانند پتروشیمی، راهبردی کلیدی در مدیریت پایدار منابع آب بهشمار میرود. در سالهای اخیر، افزایش آگاهی نسبت به بحران کمآبی و آلودگی منابع آبی، همراه با الزامات قانونی محیطزیستی و هزینههای بالای دفع پساب، توجه گستردهای را به فناوری تخلیه مایع صفر (Zero Liquid Discharge - ZLD) جلب کرده است. در این مقاله، ضمن معرفی سیستم ZLD و قابلیتهای استفاده آن در طی فرآیندها و عملیاتهای مختلف صنایع پتروشیمی، مزایا، چالشها و راهکارهای برای مدیریت چالشهای موجود و نیز چشمانداز توسعه فرایندی و فناورانه و تقاضای بازار برای سیستمهای ZLD و رشد مورد انتظار آنها مورد بررسی قرار گرفته است.
