Karahan, Selim; Karademir, Arif
Today, the increase of industry rapidly, water pollution was caused Especially, the pollution of nature with random industrial wastewater were affected all living and non-living organism. For the sollution of this problem, after treatment wastewater were purified by industrial mills used intensive water. The paper mills are also the one of the industries which use the water intensive. In these mills consisted of waste sludge. This sludge is left to nature with backwashing water. It is thought that it contributes to the national economy by evaluating the sludge in the waste way. In this way, waste sludge also by entering recycle will have transformed again a helpful case for both people and nature. In this study, waste sludge obtained from Kahramanmaraş Paper Mill (KMK), which processes wastepaper, was used. After various processes, clay, calcium carbonate, starch, resin etc. Were added to this slurry to produce the material. Then, press was applied to these materials. Then these materials were dried. Finally, laboratory tests were performed for all produced materials. As a result of the tests carried out with the waste sludge added to the wastepaper mixture in the specified ratios; breakage index value and burst index value of 5% of waste sludge participation max. has reached the value. On the other hand, cobb and air permeability values decreased while ash value increased.

Çalışmada, önce lazer baskı uygulanmış beyaz A4 ofis kâğıtları üzerinde hamurlaştırma işlemleri uygulanmıştır. Dahasonra ise hamurlaştırılan ofis kâğıtları üzerinde belirlenmiş oranlarda karışımlar hazırlanmıştır. Bu hamurlaştırma vekarışım hazırlama sürecinde ise farklı yüzde oranlarda kimyasal ve enzimden faydalanılmıştır. Kimyasal madde olarakoleik asit, sodyum hidroksit, sodyum silikat, kalsiyum klorür ve hidrojen peroksit kullanılmış ve enzim olarak iseselülaz, ksilanaz, amilaz ve β-gluktonaz kullanılmıştır. Çalışmada daha sonra ultrases etkisine bakılmıştır. En sonundaise hamur süspansiyonu yüzdürme yöntemi ile mürekkeplerinden uzaklaştırılması yapılmıştır. Tüm bu işlemler sonundaise atık su analizleri yapılmıştır.

In this study, pulp processes were carried out on office (A4), coated, corrugated board, NSSC (Neutral sulphide semi-chemical pulp), newspapers and blend papers. At the end of this process, beating followed by deinking. At the end of the process, some tests were made on the test papers obtained. For this purpose, sodium hydroxide, hydrogen peroxide, sodium silicate, oleic acid and calcium chloride were used according to the method of ingede.
