Assessment and Optimization of Electrochemical Treatment of Typical Raw Water

Abstract

This article provides a brief report on electrochemical treatment of selected raw water. Raw water samples were collected from selected villages in Katsina and Osun states, Nigeria. These water samples were subjected to electrochemical treatment using statistical methods (orthogonal technique). Selected pollutants were monitored in term of water quality. Operational factors were optimized using steepest ascent technique and environmental engineering application of the ndings was provided. The study revealed that factor with signi cant effects on ef cacy of electrochemical treatment plant process at 99 .5 %con dence levels are sedimentation time, treatment time, chlorine added, and turbidity. Model equation for ef cacy of the process based on the selected factors can be expressed as 60.68-2.26Tu+1.30Cld+1.10Ts+0.66St- 0.22Db. Operating cost of the process in US dollar (USD) can be expressed as 0.016 Es, while size of the required sedimentation tank per unit volume can be expressed in relation to optimum treatment time as 6.538 Rt . It was concluded that the system is cost effective, economical and effective in removing selected pollutants.

Arıtılmamış Suyun Elektrokimyasal Muamele ile Değerlendirilmesi ve Optimizasyonu

Abstract

Bu makalede, arıtılmamış suyun elektrokimyasal muamale üzerine kısa bir bilgi vermektedir. Ham su örnekleri Nijeya’nın Katsina ve Osun eyaletlerindeki seçilmiş köylerden toplanıldı. Bu su örnekleri istatistiksel yöntemler kullanılarak elektrokimyasal muamelye tabii tutuldu ve su kalitesi bakımından değerlendirme yapıldı. Operasyonel faktörler en dik çıkış tekniği kullanılarak optimize edildi ve basit çevresel mühendisliği uygulamaları sağlandı. Çalışma, %99.5 güven seviyesinde elektrokimyasal proseslerin etkinliği üzerine sedimantasyon zamanı, muamele süresi, eklenilen klor ve bulanıklık gibi faktörlerin önemli bir etkiye sahip olduğunu gösterdi. Seçilen faktörler baz alındığında prosessin etkinliği için model eşitliği, 60.68-2.26Tu+1.30Cld+1.10Ts+0.66St- 0.22Db olarak ifade edilebilir. Seçilmiş kirleticileri kaldırmada sistemin ekonomik ve tasarru u olduğu sonucuna varılmıştır.
