The Screw screen is an ideal solutiesion for small to medium installation. One machine carries out the screening, transportation and compaction of the screenings. The fine filtration may be circular holes (2 to 6mm) or trapezoidal profile with spacing from 0.5 to 2mm.
The Screw screen can be provided for direct installation in a concreate channel or in a stainless steel tank withh effluent inlet pipe connection.
The principle of operation is as follows:
The semi-circular screen retains soilds as the liquid passes them. The solids clog the holes and cause a rise in the level of the effluent causing a differential between the level of the provides the auger start signal detects the increase in absolute or differential water level. As the auger rotates, brushes fixed on the lower part of the auger clean the screening profile. The auger then transports the screenings to the compaction area. Compaction is achieved byreducing the auger pitch. The compacted soilds exit the screen out the discharge chute.

SSW– Step Screen
The step screen is a viable solution for medoum and large plants. It is in fact a system that exploits the principle of fixed and moving lamellas equidistant between them. The distance between the lamellas represants the spacing of the screen itself.The step screen is installed
inside of a chhanel with an inclination from 45 to 55. The effluent liquid passes through the screen, while the soilds settele on the steps.
The eccentric motion of the moving lamells lifts the screenings that are desposited on the fixed lamellas. The movements of the moving segments is ensured by a transmission system (and cam shaft) connecyed to a geared motor unit. The distance between the lamellas and consequently the screen spacing in steps can be from 3 to 6 mm. As the screening profile is composed of bars (lamellas). the open area is importants and consequently the headloss is reduced. The screen height is adapted for the headloss is reduced. The screen height is adapted for the step screen to bbe installed in channels of considerable depth.
EFD - Rotary Screen
The efflient in to the headbox, designed to distribute effliuent meshes
may be circular holes (2 to 6mm) or trapezoidal profile from 0.25 to 4 mm.
The suspended solid particles are in contact with the drum. The slow
rotation motion of the drum then carries the particles to the outside
edge of the clrum, where a blade then removes the solids.
The fillered water enters inti top of the drum, only to exit again through the bottom,
thus acting as a from of wash water from the drum surface. A spay nozzle backwash system
is installed inside the drum to complete the washing
Filtration surface after every complete rotation is totally clean
(not clogged) and ready to repeat the cycle.
