Construction Slurry Dewatering System Working in North America Company

Our Houston branch GN Solids America LLC just sold one dewatering system to local for construction slurry treatment. This system will be used to remove out solids from slurry and recycle water from sludge. The recycled waste will be used again as building material.

This system is not only applicant for construction slurry, but also hydrovac sludge treatment. It is a integrated system, which can sort out different size particle. The system include slurry catching hopper, mining shale shaker, mud cleaner, decanter centrifuge and also chemical dosing unit. The catching hopper has a steel filter in the surface, customer can directly dump waste into the hopper, the hopper will filter out big stone to avoid it damage separation equipment. slurry though the hopper drown into mining shake. It is a big shaker with large treating capacity, in this step. The grave and big size sand, these discharged can be used as building material. Discharged liquid will feed into mud cleaner. The mud cleaner include 10 inch hydrocyclone and 4 inch hydrocyclone. 10 in hydrocyclone is for removing particle size bigger than 60um, 4inch is to remove out bigger there 25um. Mud cleaner also mounted a bottom shaker with high mesh screen, it can separate the fine tiny.
In some project, the slurry after treating by mud cleaner is enough for reuse, but in some special project ,customer will require to get the liquid mucus cleaner much better. So we will feed liquid into Decanter centrifuge for finally separation. Different with shale shaker, it utilize centrifuge force generated in high rotated speed. Different density material under this high G force will be separate off. If the solids particle smaller than 5 um, flocculant will be feed through chemical dosing unit to combine tiny solids into bigger to help Decanter centrifuge to separate out these solids.
Actually, We had provided more than 15 systems in North America. Our system is very popular due to the good separation effect and high cost-effective. Every system is customized production according to client requirement. If you have demanded on our equipment, welcome to contact us.

GN Vacuum Pump and Dewatering Screw Press Delivery to Environment Company

Last week we shipped out 3 units GN vacuum pump and one screw press dewatering machine to our old client from environment industry. This customer almost purchase all dewatering equipment and pump from GN, The quality of our equipment satisfied client, they are a big fan to GN equipment.
GN Separation and transfer is one brand of ours. GN separation main focus on developing solids-liquid separate and also material transfer. Such our shale shaker, decanter centrifuge, disc centrifuge and screw press dewatering machine. according to the material situation, we can recommend suitable mode equipment to get the best treating result.
vacuum pump

GN transfer equipment include centrifuge pump, centrifuge pump, screw conveyor and also GN solids vacuum pump. All these equipment is widely sued in the world. Such as centrifuge pump, it is 100% interchangeable with MISSION Magaum, it is one kind high efficiency and stable machine. GN Solids vacuum pump is our most feature product, it is different with normal pump, which can transfer dry solids size smaller than 75mm, and also have good performance to transfer high solids content material and high viscosity material. The transfer distance can reach 1000 meters. GN is the only China vendor that can manufacture this kind pump. In some material transfer such as oil sludge , sand ,drill cutting, GN vacuum pump is best optional.

Screw press dewatering

Screw press dewatering

Screw press dewatering machine normal to dewater the material that solids content less than 5%, which is especially good at process the organic material and soft material. The discharged solids is very dry, comparing with other kind dewatering machine, screw press is low power consumption and continuous work, easily operate and maintain. In some tiny solids material, we also recommend mix with flocculant to combine small particle into bigger one to help the machine get better dewatering effect.

Not only equipment, GN also can provide whole set separate solution, we are a manufacture with full experience technical department. If you have demanded, welcome to contact us.

Tricanter centrifuge delivery to Africa

In most waste management project, the waste material normal include vary kinds material, not only water, but also oil. This week we delivered one unit tricanter centrifuge to Africa client for the oil tank sludge treatment. Different with 2 phase Decanter centrifuge ,tricanter is 3 phase separator for liquid liquid solids separation. Which principle is same with decant centrifuge. Through the high rotating speed generate the high G force, the different undissolved material will bear different G force due to their density is different. and then the different material will be in different layer. The high density solids will settle down to the bottom of Decanter centrifuge. And the lighter solids will be on the up layer.

Decanter centrifuge

The most application of tricanter centrifuge is for oil water solids 3 phase separation. It equipped a centripetal pump inside the centrifuge rotating bowl, and it will pump the oil out of centrifuge. The solids will be push forward and discharged from small end of centrifuge, water discharged from big end. In this Africa project, waste material from the bottom of oil sludge tank. Which include large crud oil ,water and solids. Customer want to separate out the solids , water. And get the clean crude oil.
These waste was flushed thorough high pressure water. And through screw press to feed it into 3 phase decanter centrifuge. Under the more than 2000 G force, water oil and solids will be separated. In some project, we may add the shale shaker to treat the material first to remove out the big size particle, and reduce the solids content. Finally feed it into 3 phase decanter centrifuge. The low solids content will improve the treating capacity of centrifuge and also get good separation performance.

GN can provide the customized solution according to client requirement. shale shaker, Decanter centrifuge , screw press, chemical dosing unit, all these equipment may be used for client project. If you have demanded on these equipment, welcome to contact us, we will be pleased to provide technical support.
