Water purification and potential applications using hydrate gel filtration system

iltration plays a crucial role for provision of clean drinking
water. However, many people still lack access to clean
drinkable water and suffer from preventable water-borne
diseases. Filtration through a low-cost ultrafiltration-range
separation technology using hydrate gel had been developed
which enables simple and high flux production of filtered water.
This research focuses on the application of this new filtration
technology using a gelatinous layer of aluminium hydroxide
polyhydrate. Filtration using aluminium hydroxide hydrate gel
allows efficient removal of suspended particles and microbial
contaminants of 10 nm or larger in size, while small water-
soluble molecules remain in the filtrate. The filter can also have
potential applications in separate hydrophobic compounds
such as oil, milk proteins and beta carotene effectively. In
particular tests are required with the prototype prior to official
certification. Flux and microbial testing have been conducted to
evaluate the filtration efficiency. Analysis of filtered water with
turbidity, UV254 and NPOC/TN analysis demonstrated that the
hydrate gel layer worked well when increasing the gel volume
and thicknesses. Among different gel types that havebeenused,
autoclaved and aged gel showed highest flux rate and greatest
filtration performance. More effort is needed to develop
different prototypes and to discover possible applications to
enable production of affordable, clean and safe water.
