COMPARATIONATKINS AEROINŽENJERING
OIL SEPARATORS at least 5 objects of the capacity (660+590)/5 = 225 l/s, or 4 with by-pass capacity of 250 l/s
Max 2 capacity of 20l/s
Concrete bed of 20 cm
120 m2, 30 m3 10 m2, 2.5 m3
Excavation 600 m3 440 m3
Superstructure, ponds,
none 60 m3, 6 tone of reinforcement
Equipment 2 pumps FLYGT 5 m, 10 l/s and 2 kW, d. c. i. of 2 tones
CONCLUSION
Proposed solution of the oil separator installation to be just above the ground instead of large excavation and 5 m depth of covering.
Easier approach for oil suction and also silt disposal.
Negligible higher expenses due to energy consumption for pollution water pumping.
