Unlike the arsenic limit for drinking
water, the permissible limits of arsenic can considerably differ
for industrial waste water discharges
It is of practical significance
that an adsorbent performs well in realistic wastewater conditions,
which always offer more challenging conditions that affect the
adsorption process
The intention was moreover to possibly reduce
the arsenic concentrations below 0.15 mg/l which is the industrial
wastewater emission limit (EU framework water directive) set by
the European Union
