OPERATIONS
Valuable
resource
Sustainable dairy
operations involve the
responsible use of water.

W
hile water is essential to all functions of
life, it is also a scarce resource. In dairy
processing, a substantial amount of water
is used for operations, cooling and cleaning. As a result,
processors are implementing innovative solutions to
minimize water use throughout processing while also
recovering wastewater for reuse.
OPTIMIZED TECHNOLOGY
Optimizing water use upstream is key to reducing
wastewater as plants take in a significant amount
of water to clean equipment, said Andrew Smits,
corporate account manager with Saint Paul,
Minn.-based Ecolab. To that end, the company has
automated solutions to analyze the water coming
into a facility so processors can use it in an optimal
manner.
" We have ways to computer model water so we can
determine the chemistry that's required, " Smits said.
" We can tell when we're going to be putting your system
into too much stress, where we could potentially
reduce asset life or reduce efficiency to operate just
below these limits. "
Making sure boilers, cooling towers and chilled
water systems are being managed optimally is
important, as well, and automation also plays an
important role in these processes.
Nalco Water, an Ecolab company, offers 3D TRASAR
technology for wastewater, allowing companies
to automate chemical treatment of water in realtime
while also allowing for remote monitoring and
alarming. The technology was implemented at a
Nestlé milk plant in Brazil, allowing for the reuse of
condensate organic water steam generated during
powdered milk production. When the solution was
combined with other pre-treatment and heat recovery
technology, the plant was able to save more than
175,000 cubic meters of freshwater and eliminate 25,000
cubic meters of wastewater effluent.
" When we get all that data, we can tell you how
much water you use per clean-in-place, how much
chemical you use per clean-in-place, how much that
one unit operation costs and how much water was
consumed, " Smits said. " We can go down to that
granular level to be able to help optimize a program
within a facility. "
