The rainwater from surfaced areas carries sand and finer-grained sludge. Most of the heavy metals occurring in traffic areas are bound to these solid particles.
In EuroHEK Sand and Sludge Trap the sand carried by the rainwater is separated. Thus, the sand and sludge trap contributes to the smooth operation of the oil separator and to lower running costs.
The water to be treated flows into the sand and sludge trap, which separates sand, sludge and further solids from the water. The solid-free water flows from the sand and sludge trap into the EuroPEK Oil Separator. According to the EN 858 standard, a sand and sludge trap is always a part of the oil separator system.
EuroHEK Omega 2000...5000 models are suitable e.g. for processing rainwater from a parking area.
SandSET-1000 Sludge Alarm controls the filling of the sludge storage space and indicates an alarm when the sand and sludge trap must be emptied (some 1/3 of the water capacity is filled with sand). The timely emptying of the sand and sludge trap ensures the proper functioning of the oil separator. In Omega models the SandSET-1000 is an accessory.
