Oil Sludge Treatment System to Uganda

GN Solids Control have been in waste management business from the time we spent R&D, resource & found to develop the vertical cuttings dryer, which also make us get through the bad time, when the oil price hit the floor. Now more and more countries are strict on environmental protection, though we have done a lot of things wrong, now we are going to fix it.

Oil sludge treatment, soil remediation is this kind of project, a capricious dump when the old projects are done, now more hassels need to be fixed. Oil dumps, waste mud, damaged soil etc. As a pioneer for waste management, GN have spent 2 years on TDU, thermal desorption unit research and development, now almost done.

The oil sludge treatment is more a system work, with shale shaker, decanter centrifuge, flocculant unit, heating tanks etc, to separate the solids into different phase.

As most of the oily sludge is a mixture of oil, water and soil, this oily sludge treatment is always a 3 phase separation process. Rather than a 3 phase decanter centrifuge, GN proposed a series modular equipment to do this 3 phase separation job with high efficiency. GN oily sludge treatment system has followed 3 main functions: solids and liquid separation, demulsion process and oil water separation. All the functions are realized within different tank and skid module.

Well this is not the whole system, it is part of it. This time in Uganda, a Chinese service company have packaged GN equipment, and now it is running.

With more and more experience, and upated equipment, GN will be able to supply better and better solution for the environmental protection.

4panel Screens Shale Shaker to Russia

With help of our local partner, GN shale shaker is now more and more popular, GN Solids Control is a more and more famous brand, more and more screens also shiped to Russia. Though we also have the design for 3panels, 2panels, this 4panel is the most popular one. Big capacity, high efficiency, more than enough reason for client to choose this model, and according our client feedback, if compare this with US similar products, operating on same site, can not find difference, well if the client requires same color, you will never notice, only can realize these are good products. Shaker Screens are exchangable with Swaco Mongoose series, 585x1165, composite material, more and more suppliers are doing the same now, that is also why it is very important that find the right way to improve and approve the shaker screen efficiency. GN have compared GN shaker and similar US shaker in different sites, the result is always supprising people, well not anymore in future. Also to make it official, GN have tested the screens in independent 3rd party lab in US, and already have result for the screens. GN Composite Frame Screen Advantages: 1)Automatic Robot Welding of the steel frame to have better quality and consistency. High quality fiber glass to improve plastic quality and screen temperature resistant to 140 C degree. 2) Four side tension of API during the heat press to minimize the gap between the top screen and support screens, in a result extending the screen life. Our competitor normally do not use any tension for heat press. 3)GN 3 layer wire API for API 60 and above for longer screen life, our competitor normally use 3 layer only for API 120 and above. 4)GN wire API supplier is the same supplier for Derrick and MI Swaco. 5) GN high performance wire API configuration is compliant to API RP 13C with screen life to 300-700 hours. 6) GN comprehensive line composite frame screen for GN shakers,MI-Swaco Mongoose,MI-Swaco MD-3/MD-2,Nov Brandt Cobra, Venom, VSM-300,FSI screen,Derrick 2000. And we can customized the Injection mould for your screen dimension. 7)The composite frame screen is repairable to save cost. 8)Compared to metal frame, the composite frame useable area is 10% to 20 % larger. 9)Since the composite frame is covered by plastic, it is rust resistant for long time storage up to over 5 years. For shaker screens manufacturing, now all if possible, automatically manufacturing, welding, framing etc., we also do the injection by ourselves. Contact us for more information.

A Mud Recycling System to US

The first mud recycling system was used for construction project in UK, it was designed as a mobile unit to the construction site, to save hassle of dirty mud. Normally that was one way to do it, another way is more often happend in Singapore, with a vacuum truck, the mud is transported to a certain place, and all the mud will be handled there.

This is sort of  new business, as it happend because people now care more and more about the environment. 


Lots of this kind of projects in other place also, such as Australi, and this time US. This client have their own exist mud system, to extend their business, they need one more system. The desin principle is mud similar as the one they already have. 

 For this one, shale shaker with a small tank as scalping unit, then the mud cleaner sitting in a bigger tank beside this unit, as next stage. After the desilter cleaning, the mud goes to the centrifuge, for better separation, whilst the polymer will be added, to help dosing the small particles. Then most of the solids bigger than 5micron can be separated.

Well normally the cut point of the shaker is 400 micron, the desander would be 75micron, desilter 25micron, decanter centrifuge is 2~5 micron. It is separated stage by stage. 


A small dosing unit also included in this system, for chemical enhancing, GN have several different modular design, one is put all into a 20ft container, as dewatring container; then like this one, just keep it simple, a stand unit; also can put all chemical dosing, and centrifuge in one big container. Either way have the same purpose.

Solids Control Equipment to India

Our business have been driven by repeated orders, that is also why we focus on top quality products from the first moment. When people realize the good quality price balance, they will come back. When the client finally get a chance to visit us, though they knew us from the old factory, they said this is a good company, with proud, my answer is, we are supported by good customers. It was a nice trip, since we have many projects on going, and also have all the equipment they are interested in stock. Easy for them not only check the photoes, but also the equipment itself, to feel, to touch, to test. Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since solids control is vital in keeping down costs associated with the drilling fluid. The basic design consists of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shakes or vibrates the drill cuttings, commonly shale shaker, across and off of the screens as the drilling fluid flows through them and back into the drilling fluids processing system, often called a mud system. This separates the drill cuttings, often called solids, from the drilling fluid so that it can be recirculated back down the well bore. In oilfield industry,linear motion shale shaker are widely used for drilling mud solids cotrol of oil gas well drilling for rig. As regarding this client, they use our products directly and indirectly, for quite a while they purchased a few mud systems directly from us, then they also tried package from rig companies. No matter which way, they are supprised to find our improvment, better design, more user-friendly, higher efficiency. Since they do have a lot of different shakers, no wonder for big companies, after visited our screen factory, they also very interested in buying more shaker screens, to replace their existing screens. After visited a few other suppliers, our big and well orgnised factory is also impressed all their team. After this visit, their first order is shale shakers, jet mud mixers etc., more under discussion. The latest shale shaker have the composite frame shaker screen, stainless steel shaker screen support frame, ratchet wheel screen reomover etc. Freely to contact us, visit us.

Mining Dewatering System to Vietnam

After grinding mill, need dewater the solids, with strong acid. That was the situation we had, then cooperated with client, we worked together to find a solution. For shale shaker feeding, we choose vertical Netzsch pump, after the shale shaker, the fluids to a small intermediate tank, sucked by a horizontal Netzsch pump, feeding to the GN decanter centrifuge.

To achieve higher capacity, and higher G force, this time we choose a 18in decanter centrifuge, which is GNLW453, with varible speed, the model: GNLW453-VFD, this model is equipped with a variable frequency control panel to realize the different rotary speed. By adjusting the speed, feeding rate, liquid level inner the bowl, the operator could adjust dryness of the discharged solids and clarity of the effluence. The shaker and decanter centrifuge need to be seated on a mud tank so that the liquid discharged could be collected properly. The tank is divided into 2 compartments for collect the effluence respectively from shaker and centrifuge. A mono pump is also fixed on the tank skid for transferring the sludge from tank #1 to centrifuge for further process. For this system, GN have required the materil from Vietnam to the real testing inside factory, before shipment, doing which to make sure the result is as expected. Before getting into this separation system, the operator would have a pit to collect the flushing sludge and then use a pump transfer to the shaker unit. GN’s equipment are widely used in many industries for solids and liquid separation like drilling fluids recycling, dredging slurry separation, crude oil storage tank bottom flushing water recycling etc. Welcome different applications wherever need solid / liquid separation, GN is ready to help.
