goals with biosurfactants
the use of digital
technologies for
water monitoring
is providing a
lot of benefits for
chemical processors,
especially
those with distressed
or variable
feeds. " There's a
real
challenge
to
treating distressed
water, which is frequently
the case
due to the increase in water reuse and recycling, " he
says. " The water source can change from day to day or
hour to hour and processors want the ability to observe
what's happening in their assets so that they may react
appropriately by pulling back on treatment when possible
or treating more aggressively when needed. "
Taking it a step further, says Evoqua's Kozlowski, is
the addition of technologies such as machine learning,
which can be used to more effectively provide alerts
to potential or active maintenance issues, allowing for
faster repair or adjustment before there is a significant
impact to operations. And, according to Kurita's Wombray,
digital twins can be used to replicate an entire
process so that chemical processors may try different
water-related variables to see what impact they will
have on the process and sustainability efforts before
making changes to the live process.
" These types of digital technologies, wireless solutions
and Industry 4.0 principles, including water monitoring
and analytics, as well as smart water management
practices, are increasingly prevalent, " says IDE's
Porat. " These technologies provide real-time data, remote
monitoring capabilities, predictive maintenance
and optimization of water treatment processes, resulting
in improved operational efficiency, reduced costs
and enhanced overall performance. "
" Most processors are trying to embrace sustainability
in all aspects of their business, " says Kurita's
Mowbray. " And there's a lot of new, updated water
treatment technologies that can help them lower
water use and freshwater use, reduce greenhouse
gas emissions and lower energy use overall, but the
key is coming up with a customized solution that
works for their individual water treatment needs, sustainability
goals and budget. What works for one facility
may not provide value for another. "
