GN Solids Control can design and make waste water treatment systems. Oil water separator unit can be used together with inclined plate clarifier. The function is to settle down small content of soil and sands, separate oil and water for recycling and reuse. It can be used to replace skimmer on the oil field.
For example, GN oil water separators can “Run-off” water from the rig activities is directed by the rig drains and collected in the concrete pit under shale shaker. The contaminated water generated from the activities is then pumped into the skimmer tank or inclined plate clarifier (ICP) by using the vacuum sludge pump or diaphragm pump to facilitate the separation process by gravity between the water and any free oil contaminate.
There are many inclined plates inside the inclined plate clarifier (ICP) which increase the settlement area, accelerate the settle down of soil inside the oil slurry mixture liquid, and increase the waste water discharge capacity. Liquid will flow to oil water separator device next to the ICP for getting oil and water. There is a small auger and a small diaphragm pump underneath the inclined plate clarifier (ICP) to clean out the settle down soil at the tank bottom periodically.
Once the process has been completed, the oil is transferred to the oil tank in the oil water separator skid, likewise for the clean water which goes to water tank on the same skid; the separated oil and water are then pumped into the other oil or water tanks at rig sites or at job sites. There are level gauge with its control on oil tank and water tank for high / low level control. When the level is high, the gauge control will start the pump to transfer the oil / water outside. When the level is low, the gauge control will stop the pump.
The capacity of GN waste water treatment unit is 50 m3 per hour.
Finally, the water and oil are ready to be reused back into the mud and rig operations (cleaning, dilution, mixing, etc)
