In this study, experiments were conducted on feed water and distill
water generated from simple solar still and from elix technology;
water quality analysis was done in laboratory to check the contaminants
removal efficiency from raw water samples. Changes in the
water quality may causes error in the compromised experimental
results, contaminated reagents and also may change the accuracy of
the equipment. The quality of water used in the laboratory is critical
for the success of the tests performed. Water quality parameter such
as pH, EC, TDS, COD, total alkalinity, total hardness, free residual
chlorine, sodium, turbidity, chloride, sulphate, floride, Total and
Fecal coliform and heavy metal like Pb, Zn, Cu, Fe, Mn, were analysed.
Distilled water is one of the essential components for chemical and
biological analysis in the field of analytical and medical testing. Many
distillation methods are available but they are either energy intensive
or use renewable (solar) energy like conventional solar still. In this
study, performance analysis was conducted for Non-conventional
(reverse osmosis and electro-de-ionization hybrid) and conventional
(solar still) distillation units. The values obtained were within the
standard range and it was concluded that the results of Elix water
testing from processing unit were found more promising for research
purpose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
