Automatic Floating Weir Oil Skimmer-Separator

OPERATIONAL CONSIDERATIONS

Turbulence — The signals from the skimmer are “averaged” so as to screen out false signals caused by turbulence and the mass of the skimmer is great enough that is will not be tossed about. However, turbulence (and cross winds) should be minimized as much as possible as turbulence impedes the ability of oil droplets to float to the surface. This may push the floating material to one side of the sump where it will be held away from the skimmer. The floating skimmer is programmed to run two hours after the liquid level has subsided to reduce the effect of turbulence.

Debris — Debris is frequently a problem in skimming operations and we encourage customers to take steps to reduce the amount of debris that can get into the sumps. The model #800AWS has the following debris protections. There is a screen grid in front of the skimmer that allows the liquid surface to pass easily toward the skimmer, but larger items (bottles, cans, most wood chunks, gloves, etc.) will be kept out. These items will be attracted to the skimmer and if present, must eventually be removed. In the skimmer body is a debris collector basket of approximately two cubic feet of capacity. This is intended to catch debris that gets past the outer screen. Eventually this basket must be emptied, but it is conceivable that it could easily hold a year’s accumulation of cigarette butts. The detection system in the floating skimmer will give an indication when there is debris that is interfering with the oil skimming operation. Finally, the pump intakes are screened and the oil off-load pump has a “y” trap filter.

Maintenance — With the exception of debris removal, the floating oil skimmer system should be virtually maintenance free. The pumps have been selected because of their capability to run almost indefinitely in this application. It is possible, that some types of oils (example: salad oil) may solidify and interfere with some float switch operations; even though the system is designed to minimize this type of interference and programmed to detect it, it is advisable to clean the components on an annual basis.

The “Smart Skimmer” series skims both oil and water (and debris in some instances) and accumulates the oil in the skimmer body. When the accumulation of oil is sufficiently deep, it is pumped off. This skimmer can deliver oil with no water even if skimming sheen. It is extremely versatile, and can be adapted to virtually any oily water condition. Moving parts are limited to an oil accumulation switch and to a floating, hinged weir.

The fixed weir and the smart skimmer have been used by industry for more than a decade. Although we are somewhat bias, we feel that these skimmers deserve your inspection. Consider your current oil skimming problems including maintenance, and compare this to the Skimoil Inc. oil only weir skimmers and/or our other selective skimming technologies. We Love Oil!
