Abstract

The huge amounts of sludges originate from different sources such as wastewater treatment plants of municipalities and industries. The ‘sludge’ is one of the wastes that have to be treated by various methods. The water content of the sludge increases required areas of storage and makes the processing difficult. Also, pathogenic contents of some sludges hinder their handling and their usage for various purposes. Dewatering characteristics of sludges are improved by conditioning methods. The major sludge conditioning methods include thermal conditioning, chemical conditioning and freeze-thaw. A hygienically safe and also dewatered sludge is obtained by thermal conditioning.

Özet

Belediyelerin ve endüstrilerin atıksu arıtma tesisleri gibi farklı kaynaklardan büyük çamur miktarları çıkmaktadır. ‘Çamur’ farklı metotlarla arıtımı gereken atıklardan birisidir. Çamurun su içeriği ihtiyaç duyulan depolama alanlarını arttırır ve işlenmesini güçleştirir. Aynı zamanda bazı çamurların patojenik içerikleri muamelesini ve farklı amaçlarla kulanımını engeller. Çamurların susuzlaştırma karakteristikleri şartlandırma metotlarıyla geliştirilirler. Temel şartlandırma metotları termal şartlandırma, kimyasal şartlandırma ve donma-çözülmeyi içermektedir. Hijyenik olarak güvenli ve aynı zamanda susuzlaştırılmış bir çamur termal şartlandırma ile elde edilmektedir.
