چکیده
پدیده رسوب‌گذاری زیستی[1] و خوردگی می‌توانند راندمان سیستم‌های خنک‌کننده صنعتی را به‌شدت تحت تأثیر قرار دهند. این مقاله نشان می‌دهد که استفاده از کلر به میزان کم در آب دریا می‌تواند به‌طور مؤثری از رسوب‌گذاری زیستی و خوردگی ناشی از آن جلوگیری کند. گزارش‌ها تأکید دارند که کلر با برمید، آمونیاک و مواد آلی موجود در آب دریا واکنش می‏دهد، درنتیجه روش مقابله و مدیریت باید به‌گونه‌ای صورت گیرد که غلظت باقی‌مانده کلر در خروجی کندانسورها کمتر از μM3 باشد. جایگزین‏های کلر نیز روش مقابله و مدیریت را بهبود می دهد. همچنین، در این مطالعه به بررسی روش‌های مختلف ضد‏رسوب‌گذاری و رویکردهای نظارتی که می‌توانند به بهبود این روش مقابله و مدیریت‏‌ها کمک کنند، پرداخته شده است. پایش دقیق الکتروشیمیایی و روش مقابله و مدیریت‏‌های بهینه‌سازی‌شده به اپراتورهای تأسیسات خنک‌کننده صنعتی کمک می‌کند تا عملکرد دستگاه‌ها را حفظ کنند و همزمان بر تولید محصولات جانبی حاوی هالوژن نظارت داشته باشند.

چکیده English

Biological fouling and microbial corrosion can significantly affect industrial cooling systems' efficiency. The study suggests that low concentrations of chlorine in seawater can be effective in inhibiting biological fouling and consequent corrosion. It highlights that chlorine interacts with components in seawater and that maintaining a residual chlorine concentration below 3 micromoles at condenser outlets is highly effective. A concise review of antifouling methods includes alternatives to chlorination and a monitoring strategy that can enhance treatments. Additionally, the review encompasses various approaches for anti-fouling methods and monitoring to improve treatments. Through electrochemical monitoring and optimized treatments, operators can uphold device performance and oversee the production of halogen-containing by-products in industrial cooling facilities.
