Recently GN Company received orders from two Indian Companies for different models of Screw Press, used for different projects. One project is used for municipal sewage treatment, and another project is for oil sludge treatment.

Sludge dewatering Screw Press is a new type of sludge extrusion dewatering equipment, and its working principle is screw extrusion, through strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between floating ring and fixed ring, to realize solid liquid separation.

Comparing to Filter Press and Decanter Centrifuge, Dewatering Screw Press has advantages of low power cost (Electricity), small footprint, less investment, and operation cost, etc. It is more suitable for clients in Africa and India, where power (electricity) supplying is limited.

GN Company is capable to supply material for wetted parts based on Stainless Steel 304, 316, and Duplex Stainless Steel 2507 can be customized.

Besides supplying De-watering Screw Press, GN Company also supplies Chemical Dosing Unit (it can be suitable for either Powder or Liquid chemical) and Sludge Feeding Pump for Screw Press.

GN has rich experience in supplying integrated system solution, and GN technical team has also developed customized system with screw press and polymer dosing unit installed on Truck, so it is much more convenient to transport the equipment around different job sites.
