Bu çalışmada, evsel çamaşır makinesi gri suyunun fizikokimyasal özellikleri belirlenmiş ve laboratuvar ortamında granül aktif karbon (GAK) ile arıtım performansı değerlendirilmiştir. Farklı yıkama programları kullanılarak gri su örnekleri toplanmış ve pH, elektriksel iletkenlik, askıda katı madde, kimyasal oksijen ihtiyacı (KOİ), yüzey aktif maddeler, toplam fosfat ve toplam azot gibi temel parametreler açısından analiz edilmiştir. Farklı GAK dozlarında (0,5–4 g/L) ve 30–120 dakika temas süresinde yürütülen adsorpsiyon deneyleri, optimum koşulların 4 g/L GAK ve 120 dakika temas süresi olduğunu göstermiştir. Bu koşullarda KOİ giderimi %32, yüzey aktif madde giderimi %38 olarak saptanmıştır. Kinetik analizler pseudo-second-order modeline (R²=0,98) yüksek uyum göstermiş, izoterm çalışmaları ise Freundlich modelinin heterojen yüzey özelliklerini yansıttığını ortaya koymuştur. Sonuç olarak, GAK ile elde edilen düşük giderim oranları, çamaşır makinesi gri su arıtımında mevcut yöntemin yetersiz kaldığını ve daha etkili yeni filtre malzemelerinin tasarımına ve kullanımına ihtiyaç olduğunu göstermektedir.

Physicochemical Characterization of Domestic Washing Machine Grey Water and Treatment with Granular Activated Carbon

Öz

In this study, the physicochemical properties of domestic washing machine graywater were determined, and the treatment performance of granular activated carbon (GAC) was evaluated in a laboratory setting. Graywater samples were collected using different washing programs and analyzed for key parameters such as pH, electrical conductivity, suspended solids, chemical oxygen demand (COD), surfactants, total phosphate, and total nitrogen. Adsorption experiments conducted at different GAC doses (0.5–4 g/L) and contact times of 30–120 minutes revealed that the optimum conditions were 4 g/L GAC and 120 minutes of contact time. Under these conditions, COD removal was 32% and surfactant removal was 38%. Kinetic analyses showed a high fit to the pseudo-second-order model (R²=0.98), and isotherm studies revealed that the Freundlich model reflects heterogeneous surface properties. In conclusion, the low removal rates obtained with GAC indicate that the current method is inadequate for the treatment of washing machine graywater and that the design and use of more effective new filter materials are needed.
