Designing of ultraviolet irradiation unit: Effects on disinfection performance and operating costs

The effect of the design of ultraviolet irradiation unit on disinfection performance and operating costs was investigated for aquaculture purposes. Two prototypes (H and U) were compared with a commercial UV filter (I). The water samples for microbiological cultivation were obtained from water inlet and outlet of three different types of UV units in four replicates at 15°C and 25°C of sea water temperatures. Finally, considering the efficiency of reduction the total heterotrophic bacterial load of the UV filters, although significant differences were not found statistically, the best results were obtained from U type UV chamber at both temperatures (15°C and 25°C) (P>0.05). Also, it was estimated that make 60% savings in renewal and operating costs can be possible with changing the design of UV chamber.

Ultraviyole ışınlama ünitesinin dizaynı: Dezenfeksiyon performansı ve işletme maliyetleri üzerine etkileri

Akuakültür kullanımları için ultraviyole ışınlama ünite tasarımının dezenfeksiyon verimine ve işletme maliyetlerine etkisi incelenmiştir. İki prototip (H ve U), ticari bir UV filtresiyle (I) karşılaştırılmıştır. Mikrobiyal ekim için su örnekleri 15°C ve 25°C su sıcaklığında dört tekrarlı olarak her üç ultraviyole filtrenin su girişi ve çıkışından alınmıştır. Son olarak, UV filtreler arasında istatistiksel olarak önemli farklılık bulunmamakla birlikte, en iyi filtreleme performansı, 15°C ve 25°C su sıcaklıklarında, U tipi UV filtreden sağlanmıştır (P>0,05). Ayrıca, sadece UV ünitesinin tasarımını değiştirerek bakım - onarım ve işletme maliyetlerinde %60 tasarruf yapılabileceği hesaplanmıştır.
