waste water treatment

In past couple years, besides the petroleum industry, GN also tried expanding the business to some other fields. The big bowl decanter centrifuge and dosing system are two of the main equipment that widely used in environmental protection for waste water treatment. The decanter centrifuge is used to remove the solid particles in the waste water, used together with the dosing system; the treated water could be discharged directly with national standard for environmental protection.

GN Decanter Centrifuge

Dewatering Centrifuge

By now, GN has already developed he big bowl decanter centrifuge for dewatering process. A very popular model GNLW553 in GN’s production line is the unit with 22 inch bowl diameter. The bowl length is over 3 times of the diameter. This is not the largest model GN can make. In near future, GN’s decanter centrifuge especially used for water treatment will be released. The model series would be 454 and even 554.
GN’s decanter centrifuge is VFD available for main motor, back motor and the feeding pump. All the electric components used come from worldwide famous brand. Operator could set the RPM on the HMI panel and monitor the machine running conditions.

The dosing system is designed containerized with all the components are installed inside the container. GN has both 20 feet and 40 feet model. Clients could choose high configuration that including automatic dosing system and acid/alkali mixing tank or simple polymer mixing tank.
The cured flocculation polymer is fed to the waste water and then the ultra fine solids will be gathered to become large size blocks for easy separation by the centrifuge.
