Hydro Excavation Waste Slurry Treatment

What is Hydro Excavation?

Hydro Excavation is now popular in North America for excavating soil by High Pressurized Water. Then an air conveyance or vacuum is used to transfer the mixture of water, soil, large size trash and some other materials into a debris tank. This Hydro Excavation allows for a non-destructive to excavate soil and locate underground utilities.

How to deal with the Hydro Excavation Waste Slurry Treatment?

GN Solids Control provides One Stop, Turn Key Solution to recover water and discharge the soil suitable for environment. The process diagram is as below.

1. Waste Collecting and Washing Module – the waste slurry is delivered to site via the hydro truck and then discharged to a large size collecting hopper at which bottom there are valves to discharge the slurry onto a coarse screen for large size trash separation.

The liquid with fine particles is collected in the tank located under the coarse screen. The liquid is then pumped to GN high G force drying shaker for finer solids separation. Here the operator can also use pressure flushing device to wash the slurry. GN shaker is fixed with composite frame shaker screen for longer working time and better performance.

2. Fine Solids Hydro cycling Separation Module – GN desilter with hydro cyclone manifold is fixed on a washing tank for further separation of the fine solids. The under shaker of the desilter is same model with GN drying shaker for easy maintenance. The hydro cyclone is using centrifugal force and gravity to separate the liquid and solids. The slurry is pumped into the cyclone with high speed for effectively separation process.

3. Dewatering Centrifuge Module – in this hydro excavation waste slurry treatment system, a decanter centrifuge (bowl diameter is 9 inch, 220mm) is used to remove the ultra-fine solids in the slurry. A chemical dosing system can be connected to the dewatering centrifuge to increase the efficiency of the separation.

Sludge Vacuum Pump- Professional for Transferring Sludge

The liquid, sludge, and slurry are heavy, thick, and sometimes with big Solids Content, making them difficult to transfer with normal Centrifugal Pump or Sand Pump. And sometimes the fluid is abrasive and corrosive, so it is always a problem to make pump last, or remain cost effective when there is constant maintenance.

The transfer of solids-laden water encountered particularly in mining must be done efficiently and that requires the pump to be powerful, low maintenance and capable of standing up to the possibly aggressive nature of the pumped liquid.

GN Sludge Vcuum Pump, also named as solids transfer pump. It is a pneumatic slurry transfer vacuum pump for liquid, slurry, and solids transfer. With special structure design, it can be used at tough environmental for solids transfer, high working performance and less maintenance. The pump can transfer material with high gravity and high density, solids content max. up to 80%.

The Sludge Vacuum Pump can be widely used for industrial and Municipal Waste, such as sewage treatment plants, cement plants, steel mills, railroads, oil refineries, chemical plants, foundries and power-generating stations.

The discharge is completely customized, so the transferred material can be discharged directly into a containment unit on site or sent via pipeline to kilometers away. There are almost no moving parts on our units, making breakdowns and maintenance a problem for the competition to worry about.

Welcome to contact us, GN Solids Control, sharing with you the working video of the Sludge Vacuum Pump.

Where to Find the Qualified Replacement Shale Shaker Screen with Low Price?

Shale Shaker Screens are widely used for Shale Shakers and Mud Cleaners.

Generally the screens shall be changed every 300~400 working hours, but that depends on the detailed project information. It is a Big Cost for the drilling companies/contractors or Solids Control Companies to purchase Shale Shaker Screens, especially when they buy the Original Screens from those reputable famous brands.

GN Solids Control understands the cost-effective shale shaker screens are very important for the solids control equipment.

So GN keeps researching and developing the best technology for manufacturing the Top Quality shaker screens for our clients. Now one of the major business of GN Solids Control is Shale Shaker Screen, and GN is able to manufacture around 8000 PCs of shaker screens every month. With our distribution network and cost-effective products, GN Shale Shaker Screens are popular around the world.

Oil Sludge Cleaned and Recycle

The Oil Sludge from the Crude Oil Tank, Refinery Plant, or Drilling Waste is always a big headache for the operators, while it is economy to recycle the oil contained, and the solid shall be discharged suitable for environment.

The treatment for oil sludge cannot be achieved with just one or two equipment, it shall be a system.

Today we shall introduce a Reliable and Economy Oil Sludge System from GN Solids Company.

Oil sludge is a mixture consisted of oil water and solids.

To treat the waste oil sludge and recovery oil and water, the oil, water and solids must be separated. And also it is important to dispose of the solids inexpensively and recover oil as much as possible. GN decanter centrifuge and oil water separator and thermal desorption unit is to do the job.

Brief Introduction about Working Procedure,

Firstly, the Oil Sludge pumped into the Pre-Mixing Tank for heating and mixing with chemical material.

Secondly, the sludge feed into the shale shaker for removing the big solid.

Thirdly, the sludge feed into the decanter centrifuge for removing the find solid.

Fourthly, the sludge feed into 3 Phase Separation Module, including Inclined Plate Separator, Oil Water Separator.

Fifthly, the collect the clean water and oil separately, and the Solid would be discharged separately too.

The recycled water can be reused in the washing process, and the oil is clean enough to sell to the refinery company, the solids contain oil between 2%-5% which can be sent to biodegradation or thermal unit for final disposal.

(Attn, different areas and different clients has different oil sludge and final requirements for the oil sludge treatment, following questions are needed to be clear for GN to provide the best proposal for your oil sludge treatment solutions.)

What is the origin and geographic location of the waste sludge (drilling, refinery, other)?
What is the makeup of the oil sludge (percentage of oil, water and solids)?
