GN Solids Control HDD mud recycling system helps Hong Kong Airport to stock airplane oil. Last year, GN Solids Control provides one set of 1500GPM mud recycling system to one Hong Kong HDD construction company. They use GN Solids HDD mud recycling system to treat the mud during HDD machine working.
The Hong Kong Airport oil stock project is pretty complicated, it was meant to build one undersea pipe to connect with the airplane. During the HDD working, the local government asked not to pollute the water and make any effect the natural environment. This is one the largest reason that GN Solids Control HDD mud recycling system is used.
This HDD mud recycling system is composed by 2 sets 1000GPM mud systems, it includes the following treating equipment:
1. GN Shaker
Each 1000 GPM mud system is fixed with 2 sets shale shakers. GN Solids Control also manufactures shakers screens for GN shakers. GN Solids Control is using GN made shaker screens. GN Composite Frame shaker screens are much more cost-effective than traditional metal frame shaker screens. GN Solids America LLC also has over 6000 pieces screens.
2. GN Desilter
GN desilter is the shaker fixed with 4inch hydroclones.
3. GN Mud Tank
All GN shakers and GN desilters are fixed on the top of mud tank. GN desilters feeding centrifugal pumps are also located on the side of the mud tank.
4. GN Screw Conveyor
Between these 2 mud tanks there is one screw converyor, which is used to collect all the solids discharged from shakers and desilters.
GN Solids Control mud recycling systems helped the Hong Kong HDD project work successfully and also protect the environment.
Now GN Solids Control has many sets of shakers, desilters, mud cleaners and decanter centrifuges stocking in Houston warehouse. Welcome to check these solids control system in Houston, USA. GN Solids Control is good at providing turnkey solutions.

GN Solids Control product line covers all the most used treating equipment like shale shaker, desander, desilter, mud cleaner, centrifuge, cuttings dryer. GN Solids Control is especially good at providing turn-key solutions for solids control and waste management systems.
Oil and Gas industry is one of the largest one for GN. While these years, GN Solids Control also working on to providing mud/ slurry treating systems to some other industries such as HDD, Mining, Diamond Drilling etc. Last week, GN Solids Control just delivered another shaker for one USA construction client.
GN Solids Control manufactures shale shaker, 10 inch desander treating equipment, 4inch desilter treating equipment as well as mud cleaner. Besides those above standard treating equipment, GN Solids Control also provides turnkey solutions, such as 200GPM mud system, 500GPM mud system and 1000GPM mud system.
Usually shaker is located on the top of one mud tank. For this USA construction client, they have some tanks in their site so we can only provide the shaker and shaker screens.
GN Solids Control shale shaker is only using 2 brands vibration motors: one is USA Martin and he other is Italy OLI. All the shakers delivered to USA are just shaker deck without any motors. GN Solids America will assembly USA made vibrators in USA and do some testing before deliver to customers.
This is one 4 panels shaker that GN Solids Control provided. G force up to 8.0G or 7.5 G. It’s especially good at separating water based sludge. When you choose different API nos. shaker screens, you will have different particles separated out.
Actually, the largest advantage to use GN shakers is GN Solids Control provides the most cost-effective shaker screens. GN Solids Control has over 6000 pieces screens stocking in Houston. GN Screens now has been providing to over 72 countries and regions.

As one of the famous solids control and waste management equipment manufacturers and turn-key solution provider, GN Solids Control has provided hundreds of customized solids and liquid separating systems, one of the most popular systems is GN Oil Sludge Treating System.
Last year, GN Oil Sludge Treating Systems were sold to USA, Kuwait, Qatar and Uganda etc.
In order for everyone has a better understanding, we’d like to pick up some of the questions our customers asked before:
On the Mixing Tank that feeds the second decanter centrifuge, we will want to add another 3 inch connection to the tank bottom to supply our Reactor. Another example, on the V-Bottom Tanks with screw conveyor, I will want to add an overflow weir to skim oil. This means that we will want to add some our Innovation custom design modifications. After we place the order, I would like to visit you in Houston and we would spend a day together marking up your standard design drawings with our needed modifications.
The piping connections between the mixing tanks and pumps, and pumps to decanters, are those hard steel pipes or are they flexible heavy duty hoses? Most of them are flexible hoses, not sure if they are heavy duty; few of them are hard steel pipes.
The Vacuum Transfer Pump is very impressive but 17 cubic meters per minute high pressure air consumption is too much and too expensive for this small system design. I am thinking of adding another Wilden T4 AODD pump. I don't like that the Wilden T4 pump only passes < 5mm solids. Do you have a better suggestion for the first pump to feed the Pre-Mixing Tank?
As you mentioned the solids content is around 30%, which is very hard to transfer by the other types pumps, only vacuum pump can transfer the high density and large viscosity oil sludge. However, screw conveyor might be used, but you will use one excavator to fill into a catching box of the conveyor. Obviously it's not the best option.
We will add the 20 foot Electrical Distribution Center to our system. I assume all piping connections on the various tanks will include valves? Do you use butterfly or knife gate valves? Yes, we use butterfly valves. If you have particular demands, we can modify our system. GN is especially good at providing tailored oil sludge treating system.

GN Solids Control will participate in OE Expo 2018 in Shanghai China. As one of the leading solids and liquid treating equipment manufacturer, GN Solids Control equipment are widely used in over seventy-two countries. GN Solids Control treating equipment before are largely using in oil and gas area, but now more and more GN equipment are using in environment protection area.
This year, GN Solids Control will participate in OE Expo 2018. OE Expo is one of Asian Leading trade fair for environmental technology solutions, mainly focus on water, air and soil. This show is from May 3rd to May 5th in Shanghai New International Expo Center. GN Solids Control booth no. is W2 566 in.
GN Solids Control will exhibit one decanter centrifuge and vacuum pump in OE Expo 2018.
1. GN Decanter Centrifuge
GN decanter centrifuge has several different models, include 9inch, 14inch, 18inch and 22inch size rotating bowl. GN Solids Control will exhibit one 14inch size rotating bowl decanter centrifuge in this show.
GN Solids Control rotating bowl is made of duplex stainless steel. The inside screw propeller is fixed with tungsten carbide tiles, which can be replaced after use for a long while. GN Solids Control provides turnkey treating systems includes centrifuge stand and feeding screw pump.

2. GN Sludge Vacuum Pump
GN Sludge Vacuum Pump is an effective pump to transfer high content solids. GN sludge vacuum pump doesn’t need to use electricity; all you need to do is provide the air source. The longest transfer distance is 1000m. Max solids contents can reach to 80%.
Besides GN decanter centrifuge and GN sludge pump, GN Solids Control also provides some other environment treating equipment, such as shaker, dosing unit.
Welcome to visit GN Solids Control booth to check GN decanter centrifuge and sludge vacuum pump.
