KAMBAS wastewater and sludge treatment system
designed by ENVICARE.KAMBAS is a member of
The European Rendering Industry Association.
The
Objective
The wastewater and sludge treatment system
is on of the activities KAMBAS has introduced
in order to fulfil the environmental policy
of KAMBAS.
The
Existing WWTP
KAMBAS build this activated sludge plant
in 1980. It is a to channel system with
surface airation. The flowsheet of the plant
can be seen on the following page. Through
out the plants lifetime, the preformance
has been improved radical. The plant has
been extended with pre-accumulation tank,
sandtrap and post-accumulation tank.
Design
Treatment
of reject from the sludge mineralisation
process. The average outlet flow of reject
water from the mineralisation cells is 10
m3 per day. The reject will be rich of nitrogen
in form of ammonia.
Post-treatment
of 300m3 wastewater per day from activated
sludge plant at the factory.
Wastewater is pumped from the wastewater
pump station alternated to one of the two
vertical gravel filters. One filter is loaded
in seven subsequent days followed by a rest
period of seven days. The purpose of the
vertical filter is to nitrificate the ammonia
and to reduce the suspended solids. After
the aerobic treatment the water is lead
to the horizontal gravel filter. The first
part of the filter is an anaerobic/anoxic
zone and the last part, after the artificial
aeration, provides an after-nitrification
process.
After
treatment in the horizontal filter, a part
of the water can be recycled to the wastewater
pump station. Discharge to the recipient
is lead through a measuring station, where
the flow is measured continuously and samples
can be collected.
