These weeks, GN Solids Control has finished one batch of solids control equipment for an international oilfield service company, will get them delivered very soon. 
GN Solids Control has been providing the most cost-effective solids and liquid separation equipment for many years, in this batch GN provides the following equipment:

1.GN Shale Shaker
4 sets of GN shale shaker GNZS594F will be used to remove big particles (usually larger than 100 microns) from the drilling mud. GNZS594 is a linear motion shale shaker fixed with 4 pcs shaker screens. GN Solids Control is the only shaker manufacturer that can provide a full series of API RP 13C shaker screen report. 

2.GN Mud Cleaner
GN mud cleaner GNZJ594F-3S16N is a 3 in 1 unit with compact structure, 2 different sizes of cyclones fixed on the top of shale shaker. After treated by GN shale shaker, centrifugal pump feeds the drilling mud into 10 inch desander cyclones first before a second centrifugal pump feeds into those 4 inch desitler cyclones. 

3.GN Decanter Centrifuge
2 sets GN Decanter Centrifuges GNlW454ET-VFD are used after the mud cleaner. 454 is a 18 inch rotating bowl centrifuge, the first decanter centrifuge will be used to remove most of the solids by quantity, while the second decanter centrifuge will be used to remove most of the solids by sizes as they will be running under middle high speed and high speed separately. 
In case one centrifuge is broken and need to be repaired, another centrifuge can be switched to guarantee the working without disturb. 
GN Solids Control has provides many solids and liquid separation equipment to global clients for many years, with more and more successful projects running in different sites, GN Solids Control always able to provide the most cost-effective solution.

GN Solids Control has been providing slurry separation equipment for many years to global drilling contractors. Last week, GN Solids Control delivered one set of GNTBM-360 slurry separation plant to a pipe jacking engineering company. 
Several months ago, GN Solids Control also provided one GNTBM-240 to a South American client. Most of these systems have similar design, they mainly includes the following treating components:

1.Shale Shaker
Shale shaker is the first phase to remove big particles from the mud. GN coarse vibrating shaker is fixed with opening mesh polyurethane screens which last longer when remove different sizes of stones or aggregates. 
2.Desander
GN Solids Control uses 18 inch sizes cyclones to remove slurry after treated by coarse shaker, 2 pcs desander cones are fixed on the top of a finer shaker. 
After treated by the desander, slurry falls onto the screen panel, which vibrate under the liner force of min. 7 G. Here weaving shaker screens are used, all are made by GN Solids Control. GN is able to build over 8000 pcs per month, and screens are tested by USA 3rd party in order to have the ideal precise cut point and conductance area. 

3.Desitler
Multiple 4 inch desilter cyclones are also fixed on the top of a finer shaker, a feeding pump suck the slurry and pump into the 4 inch desilter cyclones where most of the solids larger than 25 microns can be removed. 
4.Feeding Pump
GN Solids Control provides different types of feeding pumps, such as centrifugal pump, submersible pump and vacuum pump etc. In this pipe jacking engineering, GN Solids Control used two slurry feeding pumps, which are wear-proof to transfer high solids content slurry. 

5.Compact structure with storage tank
A compact structure to hold all the above treating equipment, with necessary walkways, ladders or safety guide rails. Mud storage tank has level sensor to keep the slurry in a reasonable level by control the on or off of the slurry pump. Whole system is easy to move or transport. 

GN Solids Control this month finished manufacturing of one whole set waste sludge dewatering system for an environmental company, it mainly includes dewatering centrifuge, screw press dewatering machine and chemical dosing unit.
Solids and liquid separation or liquid and liquid separation is always the topic when you need to treat waste, either precious solids need to be recovered or valuable liquid need to be thickened, or harmful oil should be removed, GN Solids Control always have the right equipment for you.

1.GN Dewatering Centrifuge
GN decanter centrifuge is effectively used to dewater different kinds of slurry, among various types of GN centrifuges, the T series is especially used to dewater sludge such as oil and gas drilling mud, oily sludge, mineral water, municipal or industrial wastewater, sludge from chemicals manufacturing company such as soda white mud or salt mud dewatering.
With a half cone angle of 8 degree, the rotating bowl is made of duplex stainless steel 2205or 2304, centrifuge solids discharge ports are embed with long time last wear resistance tungsten carbide tiles.

2.GN Dewatering Screw Press
GN Dewatering Screw Press is one of the most cost-effective treating unit, compared to decanter centrifuge it is way low budget is a big lure for many clients. Dewatering screw press uses an economical way to press the liquid out from the sludge.
Same with the decanter centrifuge, a pretreating equipment is needed to remove big particles. Dewatering screw press can work continously and automatically, ideal for the sludge concentration of between 2,000 mg/l to 50,000 mg/l.

3.GN Chemical Dosing Unit
When there are too much finer particles, a chemical dosing unit is very necessary to provide polymer together with the feed slurry into decanter centrifuge and dewater screw press. GN Solids Control has standard chemical dosing unit, equipped with dosing pump, and convenient to control on the smart control box.
GN Solids Control always has the right solution for you on solids and liquid waste separation.

As one of the leading water treatment show in the world, WEFTEC 2021 has thousands of exhibitors participated. Due to COVID, there are not that less exhibitors and visitors this year compared before, but GN Solids America witnessed a fast recovery of US economy and is so glad to be part of it.
The WEFTEC 2021 was held in Chicago from Oct.16th to 20th. GN Solids America LLC participated in this show and exhibited one vacuum pump and one waste water decanter centrifuge. Along with some posters and a TV to play some working videos GN did.
Hundreds of professional visitors came to GN booth, and had a hot & friendly discussions on GN vacuum pump, GN decanter centrifuge, GN dewatering screw press as well as some other solids and liquid separation solutions.

1.GN Vacuum Pump
GN Solids Control exhibits one 20 m3/h vacuum pump, besides this pump GN Solids Control also manufactures 5 m3/h, 40 m3/h pumps. Vacuum pump is particularly designed to move heavy density and larger viscosity materials, as long as the material is flowable, GN Solids Vacuum Pump can move it in a proper way.
An air compressor must be equipped with the vacuum pump to provide driven force. Vacuum pump can not working continuously due to the air need to suck and discharge every once a while. The working period can be adjusted easily by two switched on a control box. GN Solids Control also offers automatic mode and manual mode to control the on/off of the pump.

2.GN Decanter Centrifuge
Decanter centrifuge is widely used in various solids and liquid separation, GN Solids Control exhibits one 9 inch bowl decanter centrifuge GNLW224. In fact, GN Solids Control made centrifuge has different beach angles to working as dewatering, clarifying, and thickening.
We’d like to thanks for those visitors came to GN booth during this great WEFTEC show, and we are looking forward to meet you next year in New Orleans.

Construction slurry comes from many activities, such as hydrovac excavation, horizontal directional drilling, tunnel boring, piling drilling etc. Usually this slurry is mixed with solids and liquid, which need to be delivered to liquid waste management company for further treating.
Before it might be OK to dig a pit and pour inside without doing anything, but not suitable or allowable under the new environmental protection rules. GN Solids Control has been helping thousands of client treat their slurry in an economical way and varies on the treated material sometimes GN helps client to set up a new business line with satisfying profit.

GN Solids Control has been providing construction slurry dewatering system globally for many years, today we’d like to share one hydrovac slurry dewatering sytem that we provided to a North American client.

In the old days, hydrovac slurry need to be driven by fleet to a liquid waste company, and most of the treating equipment either takes too much energy or too large to treat, and need high maintenance. While by using GN hydrovac slurry dewatering system, hydrovac contractors find a cost-effective way to treat the slurry and recover sellable aggregates, sands, silts as reusable water.
Here are the main treating equipment in GN hydrovac slurry dewatering system: GN Coarse Shaker, GN Double Deck Shaker, GN Desilter Cyclone, GN Decanter Centrifuge, GN Chemical Dosing Unit and GN Mud Tank.
As we know thousands of clients have thousands of needs, everyone is special and deserve a tailored solids and liquid treating systems. When GN Solids Control provides a hydrovac slurry system, we send experience engineers to clients working sites and communicated thoroughly on all details. GN compact design hydrovac slurry dewatering system always meet clients’ demands. With more and more systems GN provided, we are more confident to provide a successful solution.
‘Before it is waste, now it is treasure. Nobody can imagine this before’, says one of hydrovac waste management CEO.

GN Solids Control is a leading slurry treating plant solution provider. With more and more hydrovac excavation activities, a high demand on the construction slurry treating by hydrovac contractors and fleets.
GN Solids Control has provided many successful dewatering equipment to the world, such as US, Canada, Australia and New Zealand. As for this construction slurry dewatering equipment, it will be delivered to Australia very soon. It is mainly includes the following main treating components:

1.Dewatering Coarse Vibrating Screen
Primary coarse vibrating screen is the first phase dewatering process, all big stones, branches, gloves etc are blocked on the top of the hopper, slurry fall through an automatic valve into coarse vibrating screen where opening mesh screens are fixed.

2.Dewatering Fine Shale Shaker  
A double deck shaker is used as the dewatering fine vibrating screen. Two sizes of solids removed from the slurry. Flushing nozzles and anti-spraying cover are optional components to keep the shaker deck from blocking after long time working.

3.Desilter Cleaner 
Desilter cleaner is shaker fixed with hydrocyclones, feed by sumbersible pump although sometimes centrifugal pump can be also used.
4 inch cylones can remove most of the solids larger than 25 microns. Usually after treated by GN dewatering fine shaker and desileter cleaner, we can get clean and dry sands and silts. As the hydrovac truck can carry solids and water at a very large different ratio, GN Solids Control also provides vacuum drying screen unit (GN ViST) to remove more water from slurry.

4.Big Bowl Dewatering Centrifuge
Centrifuge is the key treating equipment in this whole hydrovac slurry dewatering system. Centrifuge rotating bowl and screw propeller running at high rotating speed but at different direction, push the dry solids and recover clear water.
A chemical dosing unit is used to provide flocculant into the centrifuge, most of the solids larger than 2 microns can be removed by GN decanter centrifuge.
