dosing system

GN Solids Control was firstly known as a manufacturer of drilling fluids recycling equipment that are used to remove the solids in the drilling fluids, thus the drilling fluids could be reused. In China, there are several this kinds of manufacturers who can fabricate the traditional solids control equipment like shale shaker, mud cleaner, agitator and mud tanks.
Keeping improving is one of GN’s features. In the past few years, GN has invested a lot on upgrading the traditional solids control equipment to make it easier for operation. Moreover, GN has developed many new products that keep GN a leader in the solids control industry. In the year of 2016, GN released the system for hydrocarbon recovery. It is an effective solution to treat the waste oily sludge.

Oil Sludge Recovery

GN’s hydrocarbon recovery system is a three phase separation system. It includes primary coarse solids separation shaker package, fine solids separation centrifuge package and oil & water separation package.
The working principle of GN hydrocarbon recovery system is to remove the solid particles step by step from the oil sludge. The high G force drying shaker unit is equipment with hot water spraying system for better washing performance, this process will remove most of the oil content on the solids.
Decanter centrifuge is equipped with chemical dosing system for fine solids separation after demulsification process. GN’s dosing system could be used in all kinds of dewatering system for ultra fine solids separation.
The liquid discharged from the decanter centrifuge flows into the oil water separator package. Here an inclined plate clarifier is installed for further removing the remaining silt in the liquid for clarifying the oil and water mixer. Then the liquid mixer flows into the micro bubble separation for oil and water separating.
GN’s hydrocarbon recovery system makes GN a real separation solution provider other than a solids control equipment manufacturer. GN would like to communicate with all the clients on this hydrocarbon recovery system.

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.

Features of GN Waste Water Decanter Centrifuge
1. Speed adjustable as per treated waste water condition
2. Humanized HMI operation for easy operation and reducing of manpower
3. Low consumption on polymer and energy comparing with filter press
4. Considerable protection for solids discharge port and scroll for longer lifetime

GN will release more models of decanter centrifuge for environmental protection waste water treatment. Any questions, please feel free to contact GN know.
