Low vibration and low acoustic noise
The noise is less than 80db at side of the machine.
Low vibration does not require quakeproof foundation work.
Operate 24 hours / 364 days
GRS drains solid bodies from the aperture at the bottom to avoid obstruction.
ื It is not necessary to be stopped except yearly periodic inspections.
Reduce the setting area
GRS can cut down most ancillary facility through its ability to separate and recover solid with low water content and to purify water.
Because of the vertical structure of GRS, the setting space requirement becomes about 1/3 compared with the conventional horizontal structure.
