GN 14in Decanter Centrifuge for Overseas WW Treatment

GN has completed another 14-inch sludge dewatering decanter centrifuge system for an overseas wastewater treatment plant. The package combines GN's decanter centrifuge with a chemical preparation and dosing unit, providing the customer with an integrated solution for sludge conditioning and mechanical dewatering.

This project also highlights an expanding capability within GN. Through our new chemical division, GN can now support customers with both the separation equipment and the treatment materials required for the process.

Combining Chemical Conditioning and Mechanical Separation

Effective sludge dewatering depends on more than centrifugal force. Fine and colloidal solids can be difficult to separate mechanically, making proper chemical conditioning an important part of many wastewater applications.

The dosing system allows treatment chemicals to be prepared, mixed, and introduced into the sludge prior to or during centrifuge processing. Proper conditioning promotes floc formation, helping the decanter improve solids capture and produce a cleaner liquid phase while working toward the desired cake dryness.

GN customers can begin an application inquiry through their GN representative. Feed characteristics and treatment objectives can then be reviewed with GN chemical engineers to determine an appropriate treatment approach.

GN can also supply the required process materials, including polymers, bentonite, and other chemical additives, based on the application and engineering evaluation.

By combining the centrifuge, dosing equipment, and chemical support within one process approach, GN can provide more than individual pieces of equipment. The objective is to help customers optimize the complete sludge dewatering system, from conditioning through final separation.
