Grit Classifiers

MAIND Grit Classifiers consist of a shaft-less spiral screw and conical hopper.
Effluent flows into the hopper where the grit and sand settles out. Settled grit is then conveyed, washed and dewatered by the screw, then disposed of into a container.
MN/FW Range: Grit Classifier with FW wash system
Model: MN/FW
Grit removal efficiency: ≥ 95% grain size ≥ 250 µm (0.25 mm)
VOC reduction: ≥ 97% (Organic content ≤ 3%)
Range: MN 30 FW & MN 80 FW
Flows: MN 30 FW ≤ 8 l/s, MN 80 FW ≤ 22 l/s

Grit and Sand Separators

MAIND Grit and MAIND Sand Separators consists of a shaft-less spiral screw and hopper.
Effluent flows into the hopper where grit and sand settles out. Settled grit is then conveyed and dewatered by the screw then disposed of into a container. “FILWASH may be installed to wash the sand and grit or to reduce VOC up to 60%
MN/FW Range: Grit Classifier with FW wash system
Model: MN
Grit removal efficiency: ≥ 80% to grain size ≥ 200 µm (0.2 mm)
Range: MN 30, MN 80, MN 100 & MN 130
Flows: Smallest unit ≤ 8 l/s, largest unit ≤ 36 l/s
