EQ CLASS I

(with sand-sludge)

EQ SM class I oil trap with internal sand-sludge separator NS X 100

Since precipitation carries solid particles in the form of sand and sludge to a greater or lesser extent, standard EN 858 specifies that any oil trap system must be provided with a sand-sludge separator. Sand-sludge separation consists of giving the water, mixed with suspended particles, an extra time to stand still for a moment and allow the solid particles to sink. The sand-sludge separator inside the trap is suitable for places where there are fewer solid particles and for the separation, the NS x 100 sand-sludge separator is sufficient. If there is a lot of sand and sludge, a sand-sludge separator in a separate tank must be used.

OIL SEPARATOR SIZING CALCULATOR:

Certificate

Rainwater flow rate in l/(s*ha)which corresponds to the actual conditions on site. In case there is no data available, use 80 l/(s*ha) for Estonia.
Area (ha)from which water flows into the trap

Calculation result (NS)to be rounded to the nearest highest number. For example, in the case of the calculation result where NS=8.8, EQ class I oil trap NS10 Taavis can be used.
