The Solution
Woodlands
Dairy
Anaerobic Resource
Recovery Facility
W
oodlands Dairy, 1000+ people, is
one of the largest manufacturers of
UHT milk in South Africa, marketed under
the brand FIRST CHOICE®. Woodlands Dairy
is a local, Eastern Cape processor of farm
fresh milk, who produces and packages high
quality dairy products. Dairy farming methods
should not only have a minimal impact on
the environment but should also be animal
friendly and boost public support for dairy
farming.
The challenge
Veolia Water Technologies South Africa (Pty)
Ltd was awarded the contract by Woodlands
Dairy (Pty) Ltd to provide a viable processing
solution for their growing process effluent
stream. The facility contains a milk sterilisation
and packaging plant as well as a cheese
factory. All process effluent is sent to a
combined effluent sump.
Veolia Water Technologies proposed a resource
recovery plant (RRP) capable of processing 1.5
MLD, which will later be upgraded to 2 MLD.
The RRP will make use of Biothane’s state of
the art Memthane® technology, capable of
removing >95% of effluent COD.
A piloting study was performed to provide an
effluent specific treatment facility, ensuring
product performance and client satisfaction. �
