GREASE trap ST
Concrete fat separator GREASE trap ST is a grey water pre-treatment for domestic or similar wastewater (especially kitchen), restaurants, fast foods, canteens and food industries containing organic fat and oils.
Grease separator limits all problems relevant to the presence of organic oils, fats and scum in channels and treatment plants. Its installation, typically located on the grey water line, upstream of a small treatment plant or, as often required by law, upstream to sewer connection preserve pipeline from clogging and increase plant efficiency.
Concrete GRASE trap ST is made of a single prefabricated reinforced concrete tank.
Nominal size (NS) is the main dimensional parameter according to European standard EN 1825-1 and EN 1825-2.
The system is equipped with sludge trap to hold the heavier material and stainless steel baffles to create calm areas and grease accumulation zone.
It works only by gravity. In domestic effluent, oils and fats rise on surface by flotation and then they are accumulated and periodically removed with cleaning operation.
Concrete GRASE separator ST is a mono-bloc (single unit) reinforced concrete tank for underground and aboveground (available on request) installation.
Available for vehicle access (light or heavy), with concrete, stainless steel or cast iron manhole cover (available on request).
Three category available: B125, C250 or D400.
GREASE ST line is available from NS 2 up to 25, gross dimension are shown in table as follow.
NOTE: sizes can be changed without notice.
The letters in figures and table have the meanings set out below:
NS – nominal size according to EN 1825-1 and EN 1825-2
DN – inlet and outlet pipes nominal diameter
B – total gross width
L – total gross length
H – total gross height (excluding cover)
