8 Sets Inclined Plate Clarifier and 6 Sets Decanter Centrifuge for mud treatment6 Sets Decanter Centrifuge for mud treatment

Recently GN separation completed 8 sets inclined plate clarifier and 6 sets decanter centrifuge, 8 sets inclined plate clarifier will be sent to overseas customers for industrical sludge treatment, 6 sets decanter centrifuge will be sent to the domestic major drilling company for driiling mud treatment.

In this order, the overseas customer choose the model of GNIPC-25A for inclined plate clarifier, GN IPC design incorporates inclined plate settling surfaces pitched at a 55° angle from the horizontal with uniform plate spacing. Due to plate angle the solids slide down the plates into the sludge hopper below the plate pack. Herewith pls find the following photo

Chemical like polymer pretreatment often improve solids removal effeciencies. The use of chemical flocculants with GNPIC inclined plate clarifier is depend on the efficiency of the system and so on.

In regards to these 6 sets decanter, customer choose the model of GNLW453-VFD with the bowl diameter 450mm and bowl length 1540mm, it equip with 2 motors(Main motor is 55KW and back drive motor 22KW) and VFD control cabinet.

GN decanter centrifuge

GN dewatering decanter centrifuge is T series decanter centrifuge with beach angle of 8.5 degrees. T series decanter centrifuge is generally used dewatering and thickening purpose.

Sludge Decanter Centrifuge are used for sludge dewatering without chemical conditioning, but when the sludge is conditioned with polymeric electrolytes, the solids retention rate and the quality of the liquid after centrifugation are significantly improved. The centrifuged liquid slopes back to the sludge thickener or initial settling tank. The water content of the sludge cake is approximately 70-80%. The sludge centrifugal dewatering centrifuge requires a smaller site area than a vacuum filter with the same production capacity and has lower capital costs.

The advance of the decanter centrifuge

1、Continuous automatic operation

Decanter centrifugal dewatering from pumping out sludge, injecting medicine, discharging sludge cake are automatically controlled, through the electronic control cabinet, and into the sludge pumps, dosing pumps, etc., linkage, do not need personnel to operate the equipment, the operation will not be clogging, filtering away from the bias or other phenomena affecting the safety of the process, the daily maintenance of maintenance simple, 24 hours can be continuous unmanned operation. The sludge dewatering continuous full-automatic operation is realised in the real sense.

2、Saving project investment

The decanter centrifugal dewatering machine itself has the function of sludge thickening, and it can directly deal with aerobic sludge in the aeration tank without thickening and storage unit, which reduces the overall space occupied by the sewage treatment facility and the construction cost.

3、Machine body is light and durable

Decanter centrifuge due to the direct use of mechanical centrifugal separation dewatering, without the need for large-scale body, so the machine is designed to be quite lightweight; almost all the body is made of carbon steel or stainless steel, with a long service life and durability.

GN BIG BOWL DECANTER CENTRIFUGE FOR OVERSEAS MINING TAILING DEWATERING PROJECTS

This week GN completed a big bowl decanter centrifuge for oversea mining tailing project. The decanter centrifuge will be installed in container for easy transportation. The system includes 2 containers installed up and down.

In this order, customer has choose the largest model GNLW764 of GN company, Which come with 30 inch bowl diameter for large flow requirement on site. Take the inner parts protection of the decanter centrifuge consideration, we choose tungsten material plate and bushing for the decanter on screw prospeller blade, which will extend the service life of the equipment.

This GNLW-764 decanter centrifuge is a solid-liquid separation equipment, which come with 131 inch bowl length, and Max speed is 2650RPM, the material of screw is duplex stainless steel 2205, we also choose the tungsten carbide tiles protection.

At the same time, the centrifuge equip with stainless steel VFD control panel, which can make the service life more longer. And the famous brand electric components make the after-sales more convenients. you Can buy them locally.

For more information on the mining tailing dewatering centrifuge, please feel free to contact GN Separation.

GN sludge vacuum pump

Recently GN completed 2 set sludge vacuum pump, they will be arrange to the oversea customer as soon as possible. This order is engaged in the cleaning service of Storage tank.

GN sludge vacuum pump is a fully pneumatic converying equipment that need to contact a air compressor. GN have 3 models for sludge vavuum pump, GNSP-40, GNSP-20, GNSP-10. For this order, customer have choose the biggest model, which with more suction distance up to 50 Meters, discharge to 500-1000 Meters. The transferred solids size maximum is 75mm, sludge solids content up to 80%.

The handling capacity of model GNSP-40B is 40M3/H(for clean water), it equip with 4” inlet/outlet size quick joint, the request of the vacuum degree is 85Kpa/25 inch HG(mercury Column), and the air demand is 17M3/Min(600CFM).

For the different material to process,we supply different material of the sludge vacuum pump, such as carbon steel and SUS 304 stainless steel and SUS316 stainless steel.

The control cabinet is Pneumatic Control, for GNSP-40B we have both Automatic and Manually, for more information, please contact GN.
