| dc.description.abstract | Abstract: The government of Sri Lanka has
established a Community-Based Organization
(CBO) to supply safe drinking water on a payment
basis through the application of electrically
driven Brackish Water Reverse Osmosis (BWRO)
plants in CKDu-impacted areas. Due to major
drawbacks such as cost, issues in regular
maintenance, membrane clogging, lack of
expertise to rectify the defects encountered in
electrically driven BWRO plants, etc. In this
design, a multistage centrifugal high-pressure
pump was integrated with the BWRO plant and
drastically, bring down the manufacturing cost.
Then, evaluate the performance of the Brackish
Water Reverse Osmosis system powered by solar
electric energy under Sri Lankan weather, and
environmental circumstances, and enhance the
recovery ratio up to 75% through an automated
mixture. The novel design of the solar-powered
BWRO plant can be manufactured locally at a low
cost, and hence it would be the ideal replacement
for imported BWRO plants to access high-quality
drinking water for the farming community who
could not have sufficient wealth to obtain safe
drinking water on a payment basis The solarpowered BWRO plant is considerably reduced the
government overheads to subsidize the water
purification cost up to 90% of the existing
expenses. Further, it leads to protecting the
environment by reducing Green House Gas (GHG)
emissions with a more than 75% of recovery ratio.
Further, cost comparison of SLN manufactured
BWRO vs imported BWRO in a similar capacity
revealed that the SLN-manufactured BWRO plant
was 7fold cheaper than that of the imported
BWRO plant. | en_US |
