| Summary: | Desalination allows to pipe viable water supply from ocean, the largest water
resource, as potable water for drink and daily usage. The technology such as thermal
distillation and membrane separation technology requires intense energy source.
Almost all desalination plants using fossil fuel as their primary energy source, which
leads to many challenges. Marine-euryhaline Synechococcus sp. strain PCC 7002, on
the other hand, is one of the potential cyanobacteria that may contribute to the
development and advancement in water treatment field. These cyanobacteria are
able to generate a huge amount of biomass and producing fresh water (low-salt
saline water). Thus, this leads the study to investigate the influence of process
parameters on biodesalination by Synechococcus sp. PCC 7002 associate to growth
rate of the cyanobacteria. The results showed that temperature, light intensity and
pH play important role in sodium reduction. More than 50% of salinity reduction was
obtained at optimum condition. Interactive effects between selected factors
concluded that higher salinity removal was observed at temperature of 36oC with the
pH of 10 and light intensity of 3500 lux. However, the growth is contrast to
biodesalination. Interaction effect between temperature-pH, suggested that the
growth prefer near neutral condition regardless of the temperature. When
temperature interacts with light intensity, inverse relation of these two factors
resulted of higher growth rates. Further study is required to understand
biodesalination by Synechococcus sp. and its growth. Nevertheless, the study has
shown that biodesalination by Synechococcus sp. has the potential in biodesallination
process and integration with current technology for potable water source can be
further investigated. |
