Dewatering presses ARK

Screw press type dewatering machine ARK is designed as an easy and compact equipment saving footprint and easy to maintain. Screw press is ideal for increasing profitability as a consequence of the possibility of a fully automatic operation while minimizing human intervention. Basically dehydrator body is divided into two parts - the thickening and dewatering. In the area of thickening of the sludge contained in the necessary body condition for dehydration by adding flocculants. Next thickened sludge is fed into the dewatering zone, where the screw is pushed in the direction of diminishing the discharge of dewatered cake long spiral auger. The housing consists of a tube which is formed by closely setting fixed and movable rings are mounted on the shafts. Inside this tube set screw with decreasing lead turn. The liquid escapes through the gap between the rings, and the solid particles continue to move the screw and at the same time pressed sludge decreasing pitch screw. When moving the rings themselves purified gap between the fixed and movable rings. Part of the liquid leaves flocculating sludge by gravity, the residue is pushed into the upper section of the dewatering zone by reducing the pitch of the screw and finally pressed adjustable pressure plate.

1. The sludge is fed into the tank flocculation slurry feed pump.
2. Flocculation tank linking reagents are added and slurry entering them into reaction generates floccules. After the slurry is fed into the flocculation zone and then thickening and dewatering.
3. The thickened sludge is continuously moved to the exit zone undergoing condensation, in which the liquid is separated by gravity enters the dewatering zone.
4. Turning to the sludge dewatering zone is compressed by reducing the pitch of the screw and finally further squeezed completely adjustable pressure plate. The separated filtrate is returned to the beginning of the process, so it contains a quantity of suspended particles.

The working part consists of a rotating screw and the filter portion of a movable ring, which move during rotation of the auger. Mobile and fixed with a screw ring formed uniformly distributed in the filter slot of the corresponding screw threads. in suspended particles.

The distance between the rings in the filter portion gradually decreases (0,5-0,3-0,15mm) toward the exit cake. Also it decreases and pitch screw threads. As a result, the pressure inside the cylinder of the rings increases and squeeze any excess fluid. Also, the pressure inside the cylinder increases due to the pressure plate.

Screw thickener for thickening low concentrated sediment formed in the process of wastewater treatment, household, industrial, agricultural and other.

	It is used for sludge treatment before being fed to a belt press and digester.
	Installing sediment thickens humidity 99 - 97% humidity to 94 - 92%.
	The thickened sediment is stable. Selection of suspended particles is 95-99%.
	Thickener is designed in such a way that does not require rinsing water at all.
	The design of the installation is very simple and does not require regular maintenance.
	Installation works automatically and does not require permanent attendance.
	If you use a screw thickener with belt filter presses, the performance of the filter press will increase significantly. Also screw thickener can work in tandem with him.
