İçme Suyu Arıtma Çamurlarının Geoteknik Özellikleri ve Faydalı Kullanım Alanları

Öz

İçme sularının arıtımı sırasında su içeriği yüksek (genellikle ağırlıkça %95’den daha fazla) çamur ortaya çıkmaktadır. Genellikle koagülasyon işleminden ortaya çıkan bu çamur, kullanılan koagülant türüne bağlı olarak alum ya da demir çamuru olarak adlandırılmaktadır. Katı madde miktarı az, su içeriği fazla olduğu için büyük hacimler oluşturan su arıtma çamurları arıtma tesislerinde işlenmesi ve bertarafı sorun oluşturan bir atıktır. İçme suyu arıtma çamurlarının çeşitli alanlarda faydalı kullanıma sunulması bu atıkların bertarafıyla ilgili problemleri de ortadan kaldıracağı için büyük önem taşımaktadır. Bu çalışmada, içme suyu arıtma çamurlarının genel özellikleri hakkında bilgi verilmiş ve geoteknik alanındaki faydalı kullanım alanları incelenmiştir.

The Beneficial Use of Water Treatment Sludges in Geotechnical Engineering

Öz

During the treatment of drinking water, sludge with high water content (usually more than 95% by weight) occurs. This sludge, which usually results from the coagulation process, is called alum or iron sludge, depending on the type of the coagulant used. Since the the amount of the solid matter in the sludge is low and the water content is high, the produced water treatment sludge constitutes large volumes, and therefore the treatment and disposal of water treatment sludges in the treatment plants cause problems. The beneficial use of drinking water treatment sludge in various fields is of great importance as it will eliminate the problems related to the disposal of these wastes. In this study, information about the general properties of drinking water treatment sludges were introduced, and the beneficial uses of these sludges in geotechnical applications were investigated.
