THE FILTERABILITY OF SPRING WATER WITH DIATOMITE MEMBRANE FILTER

Year 2011, Issue: 024, 107 - 116, 15.04.2011

Abstract

The purified natural diatomite has high surface areas,
and thus the material used for membrane fabrication is advantageously for water
filtration. However, the diatomite membrane produced as deep-bed microstructures
did not high performance where the pores of the diatomite were clogged by the
filtered particles and thus the filtration rate was diminished. In membrane
technology, the recent studies are focused on the multilayer fabrication where
the filter easily cleanable by backflushing and thus produced long time usage. In
this study, the diatomite filter was fabricated using purified diatomite as a coating
material onto a silica substrate. Filtration testing of the present filter was performed
on spring water (located in Kütahya-Türkmendağ) which contained clay particles
being the mean particle sizes of at about 0.5
mm. The
filtration response of the membrane filter was tested in periodic pressure
filtration modes with the pressure of 5 bars. The feed water contained
sub-micron particles with the turbidity of two nephelometric turbidity units
(NTU). The filtration testing indicates superior filtrate clarity (0.1 NTU
turbidity) and the periodic filtration proved high separation capacity as 0.16
m3/m2.

KAYNAK SUYUNUN DİYATOMİT KAPLAMALI MEMBRAN FİLTRELER İLE SÜZÜLEBİLİRLİĞİNİN ARAŞTIRILMASI

Year 2011, Issue: 024, 107 - 116, 15.04.2011

Abstract

Doğal diyatomit, yüksek yüzey alanına sahip olması
sebebiyle membran filtre üretiminde yaygın olarak kullanılmaktadır. Su
filtrasyonu amaçlı üretilen bu filtrelerin çalışma prensipleri derin-yatak olup
filtreler zamanla tıkanmakta ve süzme işlemi durmaktadır. Son zamanlarda geri
yıkama ile temizlenebilen ve uzun süreli süzme sağlayan filtrelerin üretilmesi
konusunda çalışmalar yapılmaktadır. Bu çalışmada, silika altlık üzerine
zenginleştirilmiş diyatomit tozu kaplanarak üretilmiş membran filtre,
Kütahya-Türkmendağı’ndan çıkan kaynak suyunun süzülmesinde test edilmiştir.
Kaynak suyunda bulunan kil tanelerinin ortalama çapları 0.5
mm’dir. Süzme işlemleri 5 bar basınç altında yapılmış olup
filtrasyon periyodik olarak uygulanmıştır. Burada süzme periyotları 5 dakika
olup her süreç sonunda filtre geri yıkama ile temizlenmiştir. Bu testler ile
filtrenin süzme kapasitesi ve süzülen suyun berraklığı belirlenmiştir. Membran
filtre ile süzülen suyun bulanıklılığı 2 NTU değerinden 0.1 NTU değerine
inmiştir. Aynı zamanda filtre yüksek süzme performansı sağlamakta olup her
periyodik süreçte 0.16 m3/m2 süzüntü vermektedir.
