The study aimed to evaluate the presence of bacteria (total and thermotolerant coliforms) in the treatment of water using Class C Ultraviolet Radiation (UV-C), the research was carried out in the Quality Control Laboratory of the Treatment Plant of Potable Water of the EPS, EMSA Puno, because current regulations require that total and thermotolerant coliform readings in drinking water should be 0 CFU / 100 ml, with UV-C radiation being an alternative for the decrease in Chlorine use. For what was experimented with a dose of 0,00176 W/cm2/s of UV-C radiation with a dominant wavelength of 254 nm, the experimental water samples were subjected to 1, 2, 3, and 4 seconds of exposure to the mentioned radiation. For the determination of the bacterial presence in water (total and thermotolerant coliforms), the Membrane Filter methodology was chosen, the results obtained for the total coliform count were readings on average of 200, 165, 59 and 0 CFU/100 ml and for the count of thermotolerant coliforms average readings of 4, 3, 1 and 0 CFU/100 ml. Concluding that, for the total inactivation of the total coliforms and thermotolerant coliforms present in the water samples, a minimum time of 4 s of exposure to UV-C radiation was required.

هدفت الدراسة إلى تقييم وجود البكتيريا (القولونيات الكلية والمتسامحة مع الحرارة) في معالجة المياه باستخدام الأشعة فوق البنفسجية من الفئة C (UV - C)، وتم إجراء البحث في مختبر مراقبة الجودة لمحطة معالجة مياه الشرب التابعة لـ EPS، EMSA PONO، لأن اللوائح الحالية تتطلب أن تكون القراءات القولونية الكلية والمتسامحة مع الحرارة في مياه الشرب 0 CFU / 100 مل، مع كون الأشعة فوق البنفسجية من الفئة C بديلاً عن الانخفاض في استخدام الكلور. بالنسبة لما تم تجربته بجرعة 0.00176 واط/سم 2/ثانية من الأشعة فوق البنفسجية ذات الطول الموجي السائد 254 نانومتر، تعرضت عينات المياه التجريبية لثواني 1 و 2 و 3 و 4 من التعرض للإشعاع المذكور. لتحديد الوجود البكتيري في الماء (القولونيات الكلية والمتسامحة مع الحرارة)، تم اختيار منهجية مرشح الغشاء، وكانت النتائج التي تم الحصول عليها لإجمالي عدد القولونيات قراءات في المتوسط 200 و 165 و 59 و 0 CFU/100 مل ولعدد القولونيات المقاومة للحرارة متوسط قراءات 4 و 3 و 1 و 0 CFU/100 مل. وخلصت إلى أنه بالنسبة للتعطيل الكلي لمجموع القولونيات والأشكال القولونية المقاومة للحرارة الموجودة في عينات المياه، كان هناك حاجة إلى وقت لا يقل عن 4 ثوانٍ من التعرض للأشعة فوق البنفسجية.
