GN Company completed production of one complete set of Screw Press Dewatering System, including Screw Press, Sludge Feeding Pump, Polymer Preparation & Dosing Unit, and plan to ship to European client’s job site soon. The system would be used for sludge dewatering in a small municipal sewage treatment plant.

Dewatering Screw Press is a newly developed equipment of sludge dewatering equipment, and mainly used for sludge dewatering in wastewater treatment. Comparing with Filter Press or Decanter Centrifuge, it has obvious advantages of low investment, low operation cost, and low energy cost. It achieves dewatering by principle of screw extrusion, through the strong squeezing force, which is generated from the change of screw diameter and screw pitch, and the tiny gap between floating ring and fixed ring.

GN Company now has capability of manufacturing screw press with diameter 100mm, 130mm, 200mm …… 400mm, with per unit capacity of 0.1m3/hour to more than 100m3/hour. The wetted part, which is contact with sludge, is generally made of stainless steel 304, 316, and duplex stainless steel 2205 is also available, especially for sludge with high content of chloride, as duplex stainless steel has much better performance of corrosion resistance.

Besides supplying single unit of dewatering equipment, GN Company is also capable to manufacture and supply the supporting equipment, such as Sludge Feeding Pump (progressive cavity pump), Polymer Dosing Unit, Screw Conveyor (used to collect and transfer sludge cake), Tank, etc.

GN Technical Team is also capable to design and supply the whole system in containerization or on skid.

Welcome to contact GN Sales Managers, and they would offer specified solution based on clients’ projects.

GN Company is a professional manufacturer of Solid Liquid Separation Equipment, including 2/3 Phase Decanter Centrifuge, and 2/3 Phase Disc Separator. Recently GN Company arranged shipment of two units of high G-force Disc Separators to client in Middle East, which is used for coolant clarifying in the fabrication of aluminum beverage cans.

This Middle East client purchases 3-Phase Disc Separator, which is used for light phase (oil), heavy phase (water), and solid separation. 3-Phase Disc Stack Separator is a high speed, stable and automatic slag discharge centrifuge machine. The sludge material is feed into the bowl of the Disc Separator and clarified in the disc group. Through the very narrow disc compartment, the liquid is divided into thin liquid layers, and the settling displacement is reduced to a minimum. The clarified liquid is squeezed to the center of the drum and then flows to the holder cavity, where the light liquid will pass through the holder and be discharged without foam under pressure. The solid particles will be accelerated to move toward the underside of the disc, and flow out into the slag cavity, and the separated ash will be periodically discharged through the slag outlet.

3-Phase Decanter Centrifuge can also be used for light phase, heavy phase, and slag separation. While its separation performance, especially the clarity of light phase is not as good as decanter, as separate has much higher speed of rotation, thus stronger centrifugal force.

Welcome to contact GN Sales Managers, and they would offer one stop turnkey solution based on clients’ project.

GN Company is professional manufacturer of Decanter Centrifuge and Disc Separator for over 10 years. Recently GN Company completed fabrication of one complete set of Oil Sludge Treatment Package for domestic environmental solution company. The capacity is about 15 cubic meters per hour, and the system includes 2-phase Decanter Centrifuge, 3-phase Disc Stack Separator, Polymer Preparation Unit, Sludge Feeding Pump, and supporting pipelines, etc.

2-phase Decanter Centrifuge is used for solids and liquid separation. Because of high viscosity and density of oily sludge, GN Engineers suggest doing pre-treatment on the sludge, including heating and adding demusfier. Sometimes if the solid content percentage in the sludge is high, it is better to mixture with water, to reduce solids content to about 20%. Thus the sludge is fluid bale and can be pumped to GN system. The client chooses GN a big model of Decanter for this project, with bowl size about 550mm, and length vs width ratio reaches about 4.1. All the wetted part is made of Duplex Stainless Steel 2205, which has great corrosion resistance than common stainless steel 304 or 316L.

The liquid phase discharged from Decanter Centrifuge would be feed into 3-phase Disc Separator, which is use for solid/liquid/liquid separation, and the light phase (oil) would be more purified, because of the stronger centrifuge force of Disc Separator than Decanter Centrifuge, as it has much higher speed. The light phase (oil) discharged from Disc Separator has water & solids content less than 3%, and it can be resell to refinery plant for energy.

Welcome to contact GN Sales Managers, and they would offer One Stop Turnkey solution based on clients’ requirement.
