This
DVZ-SKA ”BIOMASTER”
is type approved according to old IMO Resolution
MEPC 2.( VI). The
DVZ-SKA ”BIOMASTER”- Plus
system has been developed by using
the an additional
B

M
ass-
S
eparation-
U
nit (
BMSU
). In addition with the BMSU, the
arrangement SKA with BMSU is type – approved according to the new
IMO Resolurtion
MEPC 159 (55
) (see following P&ID).
Biological Part of Sewage Treatment Plant (STP):
Stage 1:
The STP is a biological sewage treatment plant with three compartments:
1. The
1
st
inlet – chamber is for mixing and conditioning the sewage,
2. The
2
nd
reactor – chamber is the biological reactor for treating process,
3. The
3
rd
outlet – chamber, collecting tank for biological treated water and pump
control tank,
The
1
st
-chamber which is the inlet chamber and it consists of an aeration-pipe and a
return sludge inlet (reject from BMSU).
A settling zone under the aeration pipe is considered beneath the first chamber for
collecting the solids. The aeration pipe supply the inlet sewage with oxigene and mixed
homogene incoming sewage with returne sludge.
The
2
nd
-chamber is the biological reactor (Aerated Submerged Fixed Film Unit). In this
chamber is located a submerged fix bed which rest on support and is considered as
settlement area for the microbes (immobilized). Forced by around air upstream, the
sewage will flow (circulation) over the fix bed.
The blower has to deliver the air for aeration the different chambers. After biological
treatment, the treated water passes the settling zone and over flows into the third
chamber (control chamber).
The
3
rd
chamber have two functions, collecting the biological treated water and control the
transfer pump (P5) and BMSU loading pump (P2).
