This type of STP (DVZ-SKA ”BIOMASTER”- Plus (IT)) is similar to the
DVZ-SKA “BIOMASTER” – PLUS, but the hole STP tank and the control tank is
dimensioned in bigger size (See ( a ) in above schema). This additional volume will be use
as buffer function, so that a separate buffer tank is not necessary.
If the sewage, black- and grey water feed direcly in the first chamber of STP (gravity
system), it is necessary to use a macerator for cutting large particle.
In case of vacuum system which feed the “black water” directly in the first chamber of STP
and “grey water” drain by gravity to the first chamber STP, an additional mazerator is not
necessary, because the vacuum pumps already have a mazerator equipment.
If grey water is not aviable, it is necessary to add dilution water.
Notice: For the technical equipment for dilution water and the correct volume of dilution
water, please ask DVZ Company.
Notice: For sampling the outlet quality, the sample shall be taken on the sample valve
(S) , near permeate flow meter (FI 1) .
2.2 Permeate Lift (PL):
Notice: Please notice that the back pressure to permeate connection shall not be more
than 0,5 bar. In case of higher back pressure, to lift permeate over board, it is to
install a
DVZ-PL unit .
This permeate lift is designed as separate tank with a submerged pump
and controlled by level switches.
