خدمات اعمال التركيب لجهاز الدفع الهوائي في منطقة المرحلة الاولى لمحطة المعالجة الثلاثية بمحطة توبلي لمعالجة مياه الصرف الصحي

تم تصميم مركز تحكم تلوث المياه بتوبلي لإنتاج 200,000 متر مكعب من المياه المعالجة الصحية يوميًا. يهدف هذا العقد إلى تقديم خدمات تركيب نظام إزالة الأوزون في المرحلة الأولى من محطة المعالجة الثلاثية.

يعتبر نظام إزالة الأوزون مجموعة من المعدات المصممة لتدمير الأوزون غير المتفاعل في المرحلتين الأولى والثانية. في المرحلة الأولى والثانية، توجد ثلاث وحدات بسعة 1500 متر مكعب ووحدتان بسعة 1000 متر مكعب. تعتمد تقنية إزالة الأوزون على تحويل جزيئات الأوزون الثلاثية إلى جزيئات أكسجين ثنائية من خلال تمريرها عبر مادة محفزة، مما يساعد على الحد من التلوث البيئي.

يشمل نطاق العمل توريد قطع الغيار لمدمر الأوزون باستخدام تقنية الكاتاليست وتوريد قطع غيار لمناطق مختلفة في محطة المعالجة الثلاثية. يتضمن المشروع أيضًا تعديلات لضمان التوافق مع النظام الحالي. سيضمن ذلك الإنتاج المستمر لمياه الصرف الصحي المعالجة بالجودة المطلوبة في محطة المعالجة الثلاثية.
