SkimOil Automatic Floating Weir Oil Skimmer-Separator is a self-contained skimmer purposely built for specific jobs. Originally designed for hydro dams—to go down into very deep wells and automatically skim and separate oil from water and pump the oil up to the surface —automatically.
The Descriptions of OilSkim Automatic Floating Weir Oil Skimmer-Separator
With onboard pumps, controls, and monitoring, the automatic floating weir oil skimmer is fully programable The model #800AWS will remove 100% of free and floating oils from storm and wastewater. The Auto-weir floating skimmer will automatically detect, engage, accumulate, and offload oil.
What makes the Auto-weir floating skimmer automatic is a programmable PLC that controls the basic operation, monitors conditions, and initiates preventative maintenance. All functions can be customized for site-specific operations including reporting for compliance requirements. This system is also available as the dumb cousin—without the automation—it’s still a great way to skim oil without the hassle and risk of discharging or otherwise dealing with the water.
Applications of OilSkim Automatic Floating Weir Oil Skimmer-Separator
The Auto-Skimmer removes floating oils from pits, tanks, stormwater collection tanks, or sumps. Perfect for non-point source floating oil removal such as monitoring wells, bypasses, scale pits, runway runoff, maintenance yards, mining applications, and API separators or any still water surface. Operating conditions can be monitored remotely making this oil skimmer ideal for inaccessible locations.
AUTOMATION & OPERATIONAL CYCLE
Skimming Cycle — A typical skimming cycle for a stormwater run-off sump will begin with a rise in the tank water level indicating rain. The skimming will continue for a preset period to cycle the whole surface area and remove any oils, which are coming out of suspension. If the #800AWS detects a sufficient amount of oil has been collected in the skimming cycle, the oil will be off-loaded. The floating oil skimmer will stop when the oil has been removed.
Skim Capability — The system creates a flow of surface water and floating oils (a skim) into the oil skimmer, attracting floating material from the entire surface area. Floating oil accumulates in the skimmer body and the carrier water is returned to the source through vents in the bottom of the skimmer. Skimming is continual as long as oil accumulation is indicated. The gpm of both the skim and the oil off-load is variable.
Automation — All functions are controlled with a PLC. Operational parameters are factory-set for typical use but are easily modified for optimization for a specific installation. In addition to customizing operations the PLC will monitor oil skimmer functions, advise of failures; such as the need to clear debris or pump failure, and can even report on oil recovery cycles to help with compliance reporting. The auto-simmer may be linked to central controls or function independently.
Oil Off-Load — The system will assess the accumulation of oil and off-load when there is a sufficient amount of oil collected. An oil off-load cycle will initiate another collection cycle with the assumption that all free-floating oil has not yet been removed. Only when an oil skimming cycle has been completed without the need for an offload will the system go inactive, and wait for the next “start” activation signal.
Pumps and Instrumentation — The system uses two pumps, one for oil skimming and the other for oil off-loading. The pumps are selected to fit into the customer’s environment. The oil skimmer controller reacts to changes in the liquid levels in the skimmer. This information tells the controller if a “skim” is taking place, and when sufficient oil has been accumulated to trigger an oil-off load. An ultra-sonic level detector detects the liquid levels in the skimmer. This detector never touches either the water or the oil, and therefore will not stick in old oil as float switches do. Information regarding the oil skimming operation is also passed to the PLC so that minor problems can be automatically corrected without the need for intervention.
