Kömür hazırlama tesis artıklarının koagülasyon ile susuzlandırılmasında farklı koagülant tiplerinin etkisinin araştırılması

https://orcid.org/0000-0001-6489-2229Bu çalışmada, kömür hazırlama tesis atık sularının koagülasyon ile çöktürülmesinde farklı tip koagülantların çöktürme verimi üzerindeki etkisi araştırılmış ve elde edilen sonuçlar birbirleriyle mukayese edilerek en uygun koagülant tipi belirlenmeye çalışılmıştır. Koagülasyon testlerinde koagülant tipi ve miktarı, ortam pH’sı, karıştırma süresi ve hızı gibi parametreler test edilmiştir. Her bir deney sonrası süspansiyonun türbiditesi ölçülerek koagülasyon verimleri hesaplanmıştır. Demir sülfat, alüminyum sülfat ve demir klorür ile yapılan koagülasyon deneylerinden elde edilen sonuçlara göre koagülasyon verimlerinin sırasıyla; %67.21, %88.71 ve %94 olduğu tespit edilmiştir. Deneyler sırasında koagülantların tüketim miktarlarından yola çıkarak işlem maliyetleri de tespit edilmiştir. Tüm bu sonuçlar ışığında demir klorürün diğer koagülantlara göre daha verimli ve ekonomik olduğu belirlenmiştir.

Investigation of the effects of different coagulant types for dewatering of coal plant tailings

In this study, the effects of different types of coagulants were investigated on the precipitation of coal preparation plant wastewaters and the results were compared with each other to determine the most suitable coagulant type. In coagulation tests, parameters such as type and amount of coagulant, media pH, mixing time and speed were tested. After each test, the turbidity of the suspension was measured and the coagulation efficiencies were calculated. The results of coagulation experiments with iron sulphate, aluminum sulphate and ferric chloride showed that the coagulation efficiencies were; 67.21%, 88.71% and 94%, respectively. During the experiments, the costs of the coagulants have been determined from the consumption amounts of the coagulants. All these results indicate that iron chloride is more efficient and economical than other coagulants.
