Hemodiyaliz Dünyanın Suyunu Tüketiyor: Ters Osmozdan Atılan Suyun Analizi ve Kullanılabilir Olması / Hemodialysis Consumes the World's Plenty of Water Water: the Analysis of Water Discharged from Reverse Osmosis and Usefulness
Amaç: Hemodiyaliz (HD) su sisteminde ham su; şebeke veya artezyen suyunu, saf su ise; konsantre HD çözeltilerinin seyreltilmesinde kullanılan arıtılmış suyu tanımlamaktadır. Saf su üretilirken ters ozmoz (RO) cihazından açığa çıkan ve çoğu kez kanalizasyona atılan “reddedilen su” ile tedavi sonrası hasta kanı ile temas etmiş HD atık suyu terim olarak karıştırılmaktadır. Çalışmada amacımız reddedilen suyun kalitesini göstererek atılmasını engellemektir. Gereç ve Yöntem: Hemodiyaliz dünyanın suyunu tüketiyor isimli çalışma için Manisa Celal Bayar Üniversitesi Etik Kurulundan onay alınmıştır. Suyun yüksek basınç altında yarı geçirgen zardan geçirilerek içindeki zararlı ve kirletici maddelerden filtrelenme işlemi RO sisteminin temel prensibidir. Çalışmamızda RO su arıtma sisteminde çıkan ve kanalizasyona giden suyun mikrobiyolojik ve kimyasal yönden analizi yapılmıştır. Bulgular: Merkezefendi Devlet Hastanesi HD ünitesinde su sisteminin farklı noktalarından tekniğine uygun şekilde su örnekleri alınarak Afyonkarahisar Halk Sağlığı Laboratuvarında mikrobiyolojik ve kimyasal testler yapılmıştır. Ters Osmoz su sisteminde giriş, arıtım sonrası, tanklar arası ve reddedilen su bölümleri olmak üzere 4 farklı noktadan alınan su örneklerine yapılan analizler sonucunda bu bölümlerin tamamı mikrobiyolojik yönden (Enterocuc/Fecal streptococ, E.Coli, toplam coliform) steril, Alüminyum ve Demir düzeyleri sıfır bulunmuştur. Amonyum sırasıyla 0.15, 0.13, 0.12 ve 0.13 mg/L; kondoktivite ise 540, 546, 492, 623 mS/cm, koku bulanıklık ve renk açısından uygun, pH 7.50-7.70, aynı zamanda Türkiye ve ABD EPA standart aralığında değerlendirilmiştir. Sonuç: Bu çalışma ile RO sisteminde reddedilen suyun her türlü amaç için kullanılabilir olduğu gösterilmiştir. Dünyada su kaynaklarının giderek azaldığı dikkate alındığında, kanalizasyona giden, ekonomiye ve doğal çevreye yük olan bu durumun önüne geçilerek bu durumda, suyun tasarruf edilebilir olmasını gösteren ulusal anlamda ilk çalışmadır.

Hemodialysis Consumes the World's Plenty of Water Water: the Analysis of Water Discharged from Reverse Osmosis and Usefulness
Introductıon: In hemodialysis (HD) water system; raw water describes mains or artesian water, pure water means the purified water used for dilution of concentrated HD solutions. During pure water production, the term “rejected water” is often misconstrued. This water is released from the reverse osmosis (RO) device and is typically discarded into the sewer. It is different from HD wastewater, which has come into contact with a patient's blood post-treatment. Our study aims to assess the quality of this rejected water and explore ways to repurpose it rather than disposing of it. Materıal and Method: Approval was obtained from Manisa Celal Bayar University Ethics Committee for the study titled Hemodialysis consumes the world's water. The basic principle of the RO system is to filter the water from harmful and polluting substances by passing it through a semi-permeable membrane under high pressure. In our study, microbiological and chemical analysis of the water coming out of the RO water treatment system and going to the sewer was made. Results: Microbiological and chemical tests were carried out in Afyonkarahisar Public Health Laboratory by taking water samples in accordance with the technique from different points of the water system in the HD unit of Merkezefendi State Hospital. As a result of the analyzes made on the water samples taken from 4 different points in the reverse osmosis water system, namely inlet, post-treatment, inter-tank and rejected water sections, all of these sections are microbiologically sterile (Enterocuc/Fecal streptococ, E. Coli, total coliform), Aluminum and Iron levels zero was found. Ammonium 0.15,0.13, 0.12 and 0.13 mg/L, respectively; and the conductivity was evaluated as 540, 546, 492, 623 mS/cm, suitable in terms of odor, turbidity and color, pH 7.50-7.70, also within the standard range of Turkey and USA EPA. Conclusion: With this study, it has been shown that the water rejected in the RO system can be used for all kinds of purposes. Considering that the world's water resources are decreasing, this is the first national study showing that water can be saved by preventing this situation that goes to the sewerage, which is a burden on the economy and the natural environment.
