GDE performs: screening, sand removal. GDE/D performs: screening, sand removal, oil/fat removal.
Can be supplied in 2 models: • CLS sand classifier + FCP/C screw screen in tank, with perforated rounded or wedge wire profile.
• CLS sand classifier + GRR drum filter, with wedge wire profile. Based on the chosen model, it will be possible to get a different type of screening.
The sewage goes through the screening section for the solid parts removal. Then the sewage falls down a decantation tank where the particles go down. Here an extraction spiral removes them.
