Zinc ion removal from aqueous solution using ion exchange process

Industries such as electroplating, dyes manufacturing, metal plating facilities and
other similar industries produce heavy metal which are highly toxic for human and the
environment. Zinc is one of the heavy metals discharge from above mentioned
industries and need to be treated according to the regulation limit imposed by
Malaysian government. There are several methods for removing heaving metals from
wastewater. Ion exchange process using resin have many advantages compared to
other methods hence will be used in this study. The extent of the project work are
conducting experiment to determine the influence of different operating parameters on
the zinc ion removal process specifically effect of initial concentration (50ppm,
lOOppm & 150ppm) and effect of pH (3, 5 & 7), determine the effect of regeneration
on the resin's performance and analyze the experimental data using Thomas model.
Results from this project work will be useful in designing wastewater treatment
system in the industry.
