Evaluation of Detergent-Based Washing Machine Wastewater by LCA and EoL Analysis

Öz

Environmental pollution studies have shown that the detergent problem in the structure of wastewater is increasing rapidly all over the world. Washing machine wastewater, high concentration detergents, surfactant, phosphate, suspended solids, oil, colour, etc. It appears as a part of urban wastewater containing pollutants. In this study, in order to obtain reliable data on the release of detergents and to determine the possible environmental effects of washing machine wastewater, real-scale washing trials were carried out on clothes using a household washing machine. At the end of the washing process, wastewater was collected separately for two different detergents and analyzed. Thus, the environmental impact of the detergent with boron content was also examined. In addition, environmental assessments were made for detergents and washing machine wastewater on the basis of the life cycle and EoL diagrams. As a result, according to the wastewater analysis and EoL diagram, the detergent with boron content in terms of surfactant (104.1 mg / L) and phosphate (1.506 mg / L) compared to the other detergent (MBAS = 220.4 mg/L, phosphate = 8.863 mg/L) proved to be better.

Deterjan bazlı çamaşır makinesi atık suyunun YDA ve EoL analizi ile değerlendirilmesi

Öz

Çevre kirliliği çalışmaları, tüm dünyada özellikle atıksuyun yapısında yer alan deterjan sorununun hızla arttığını göstermiştir. Çamaşır yıkamadan kaynaklı atıksularda bunlardan biri olup çamaşır makinesi atıksuyu, yüksek konsantrasyonlu deterjanlar, sürfaktan, fosfat, askıda katı maddeler, yağ, renk vb. kirleticileri içeren kentsel atıksuyun bir parçası olarak karşımıza çıkmaktadır. Bu çalışmada, deterjanların salınımı hakkında güvenilir veriler elde etmek ve çamaşır makinesi atıksularının olası çevresel etkilerini belirlemek amacıyla, ev tipi çamaşır makinesi kullanılarak giysiler üzerinde gerçek ölçekte çamaşır makinesinde yıkama denemeleri yapılmıştır. Yıkama işlemi sonunda atıksular iki farklı deterjan için ayrı ayrı toplanıp analizler gerçekleştirilmiştir. Bu sayede bor içeriğine sahip deterjanın çevresel etki boyutu da incelenmiştir. Ayrıca, deterjanlar ve çamaşır makinesi atıksuyu için yaşam döngüsü ve EoL diyagramları temelinde çevresel değerlendirmeler yapılmıştır. Sonuçta, yapılan atıksu analizlerine ve EoL diyagramına göre bor içeriğine sahip deterjanın yüzey aktif madde (MBAS) (104.1 mg/L) ve fosfat (1.506 mg/L) açısından diğer deterjana (MBAS=220.4 mg/L, fosfat=8.863 mg/L) göre daha iyi olduğu ortaya konmuştur.
