In recent years, the screw press machine is more and more popular in the waste water treatment process and also in municipal sewage treatment along with the grille and sedimentation tanks. Comparing with the grille, the screw press can remove solids particles much more smaller, and comparing with sedimentation, the scree press in more compact in size and need less time. Of course, the three are still working together as a primary treating solution before future treatment as chemical or bio-treatments.

A screw press is also called a screw stacking machine, and it plays an important role in sewage treatment because of the features such as high efficiency, energy saving, and small footprint make it a commonly used equipment in the field of sewage treatment. Here are some reasons why it is more popular:

1. Efficient and energy-saving: The screw press has the characteristics of high efficiency and energy-saving, and its operating cost is much lower than that of traditional equipment. This is mainly because the structure is compact, occupies a small area, and does not require specialized staff.

2. Small footprint: Compared to traditional processing equipment, the footprint of the screw stacking machine is much smaller, which gives it greater advantages in some limited venues, such as urban center areas.

3. High degree of automation: Modern screw presses are equipped with an automation control system, which can achieve functions such as automatic feeding, dehydration, and unloading, reducing manual operation requirements and improving work efficiency.

4. Easy operation and maintenance: The screw stacking machine is easy to operate and maintain, reducing operating costs.

In a recent project for municipal sewage treatment contract in USA, the end user chose GN Separation as its supplier for a screw press with model GNDL303. It will soon be sent to the client’s project jobsite.
