dc.description.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 CKDuimpacted 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 highpressure pump was integrated with the BWRO plant drastically bringing 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 provide high-quality drinking water for the farming
community who could not have sufficient wealth to obtain safe drinking water on a
payment basis The solar-powered BWRO plant considerably reduces the
government overheads to reduce 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 |
