Solids and Sludge vacuum pump for thick sludge at drilling waste pit

GN Solids Control makes Solids and Sludge vacuum pump to suck and transfer various types of waste material. It is popular to use before GN oil sludge treatment system to suck the oil sludge from the waste pit and feed to the separation system.
Some client want the vacuum pump is strong enough to suck thick sludge.

It is no problem to use GN sludge vacuum pump suck the upper layer oil sludge in the pit. On the upper layer, the liquid content is higher, the sludge is flow. So vacuum pump can suck it. At the bottom, the solids content maybe much high. If the fluidity is poor or unable to flow, the vacuum cannot be sucked.

It is difficult to confirm slush up to what solids content can be evacuated. It also depends on the viscosity and density.
Clients are normally suck it in 2 ways.

1) vacuum pump to suck the liquid sludge at upper layer, and separated by shale shaker, centrifuge, etc… The liquid recovered is dirty. They transfer the dirty liquid to waste pit to dilute the bottom solids waste.

2) they use vacuum pump to suck the liquid sludge at upper layer, use excavator to take the bottom solids, or they use the excavator machine for all the sludge waste.

This video is showing clients use both vacuum pump and excavator machine to suck the sludge and waste.

Another purpose of clients using GN Solids Control vacuum pump is to remove slush from Skips and drop in a pit. They are collecting the oil slurry in skips and taking them to our site for treatment and disposal. At the site we remove slurry from Skips, and treat them in TDU
