Operating Principle Biological Sewage Treatment System DVZ-SKA-“BIOMASTER“
The sewage, grey water (GW) and black water (BW) , is feed to the buffer tank by gravity
or vacuum pumps and will be delivered by transfer pump (P5) to STP. The pump (P5)
calibrat the volume flow so that the Membrane stage (BMSU) can smooth operate. The
capacity of BMSU is calculated for an operation time is 22 hours per day for treating the
daily total amond of sewage, with a 2 hours time buffer.
Sewage will be deliver from the transfer pump
(P5) via the inlet 01 into the pre-treatment
tank 11 , where intensive mixed with returne sludge (reject), by a pre-aeration tube,
placed on the under part of pre-treatment tank. The air (oxygen) will be delivered by the
blower
( 04 or G1) .
The system is ventilated to the open deck (chimney) via the air vent pipe (02) .
