Disinfection without
handling chemicals
Molkerei Hainichen-Freiberg modernises
its water treatment system
Molkerei Hainichen-Freiberg has modernised its water
treatment system: by implementing electrolysis systems
from ProMinent, it no longer needs to handle
dangerous chemicals it previously used for disinfection.
Instead, innovative systems use harmless cooking salt to
produce a disinfection solution on site. The benefits for the dairy
include a vast improvement in health and safety, lower operating
costs and consistently low water consumption.
Reduced water consumption
Every year Molkerei Hainichen-Freiberg turns 150m kg of milk into
yoghurt, blancmange, cheese and milk powder for babies. The
high consumption of fresh water for various applications, such as
rinsing centrifuges, used to be an undesirable cost factor for the
company.
Thanks to a chlorine dioxide system, the dairy has already managed
to considerably cut costs for fresh and waste water in the
past. The vapour water produced in the production process, which
contains aromas and other ingredients that promote germ growth,
is disinfected and then reused. This saves Hainichen-Freiberg
around 60,000 m³ of drinking water annually.
Increased safety
Treating water with chlorine dioxide involves the use of hydrochloric
acid and sodium chlorite. These chemicals can be dangerous
during transport, storage and handling. This is why Molkerei
