Abstract

Vacuum fitration was applied at different temperatures and filtration pressures to determine the average specific cake resistance of mud obtained from the constant pressure filtration of 1st carbonatation sludge obtained from sugar factory. Average specific cake resistance as highly dependent on the filtration pressure, which indicates that 1st carbonatation sludge forms compressible cake. The cake compressibility coefficients at 70 °C, 80 °C and 85 °C were calculated as 0.45, 0.45 and 0.50, respectively. Perlite was used as filter aid to increase filtration efficiency. The effects of the amount of precoating and body feed concentration on average specific cake resistance were also studied. The lowest average specific cake resistance was obtained with precoating-body feed technique.

Özet

Şeker fabrikasının 1. karbonatlama çamurlu şerbetinin sabit basınçta süzülmesi ile elde edilen çamurun ortalama spesifik kek direncini belirlemek amacıyla çeşitli sıcaklık ve süzme basınçlarında vakum fıltrasyonu uygulanmış, süzme işlemi sırasında kek diren¬cinin basınçla çok değiştiği ve kekin sıkıştırılabilen bir kek olduğu anlaşılmıştır. Sıkıştırılabilme faktörleri 70 °C, 80 °C ve 85 °C için 0.45, 0.45 ve 0.50 olarak hesaplanmıştır. Süzme işlemini kolaylaştırmak amacıyla süzme yardımcı maddesi olarak perlit kullanılmıştır. Ortalama spesifik kek direncine önkaplama miktarının ve çözeltiye katkı konsantrasyonunun etkileri de incelenmiştir. Önkaplama ve çözeltiye katkı tekniğinin birlite uygulandığı deneylerde daha düşük ortalama spesifik kek dirençleri elde edilmiştir.
