Said inlet (102) can be in the form of said reject or sludge can be processed by means of a screw (101) confined in a stationary screening device (104) comprising with a plurality of apertures (105) articulated on a periphery and having an even diameter without any change along the length of said screw (101) configured in order to allow water to pass from said apertures (105) and restrict any material with more size than the aperture (105) to pass from said screening device (104). In one of the embodiments said screening device (104) can be articulated in at least two parts (104a, 104c) configure with each other by means of ring (104c) at one end whereas the other end of said part (104a) can be configured with a sealing configuration (113) with respect to said inlet (102) and in case of said part (104b) the end opposite to configuration with said part (104a) can be configured with said ring (104c) and said ring (104c) can be configure with said ring (108c) respectively. Wherein said screw (101) can be supported in a bearing (111) confined in a housing (112) and rotated by means of a rotating means which include but not limits to the motor or any other rotating means in order to form a rotational assembly with said screening device (104) and generate the rotational force against said surrounding screening device (104) along the periphery of said screw (101) and said screening device (104). Further said screw (101) can include a plurality of flights (101a) fixed on the periphery with a variable pitch along the tapered base (101b) that gradually decreases in diameter, whereas the diameter of said screw (101) gradually increases along the length of said screw (101) in order to gradually reduce the peripheral effective area between said screw (101) diameter, said fight (101a) diameter with respect to said screening device (104) diameter in order to increase the effective pressure force from said inlet (102) end of said dewatering device (102) to an outlet (103) end of said dewatering device (100) in order to increase the dewatering percentage effectively under the action of said increased rotational force from said screw (101) to press said reject or sludge against said screening device (104) to release water if any from said apertures (105) of said screening device (104) and further increases squeezing of said material and provides the forward guide towards the inlet to said reject material from back force from continue input material in order transfer said reject or sludge material from said inlet (102) of the dewatering device (100) to said outlet (103) of the dewatering device (100) under the pressurized condition to release the water containing in said reject or sludge to perform dewatering action and get discharged under action push forward force to said outlet (103). In one of the embodiments the taper angle (A) of said base (101b) of said screw (101) can be in the range of 4° to 7°. In one of the preferred embodiments said taper angle (A) of said base (101b) can be at least 5°.
Further, in the second phase said already pressurized and dewatered sludge can be further pressed and pressurized in said compression zone (108) configured after said flights (101a) extending from said screening device (104) towards said outlet (103). Wherein said compression zone (108) includes a plurality of rings which include but not limited to a ring (108a), a ring (108b), a ring (108c), and a ring (109). In one of the preferred embodiments said compression zone (108) includes at least three rings (108a, 108b, 108c) in order to maintain the required pressure range area in said compression zone (108). Further, a gap (110) can be maintained between said compression zone (108) and a cone (107) in order to maintain the pressure, perform the dewatering, and extract the intended output dynamically from said outlet (103) of said dewatering device (100). In one of the preferred embodiments said gap (110) can be maintained at least 10mm.
