Oil Skimmer Care
The Dragonfly™ Micro Oil Skimmer is designed to skim oil and other floating materials from the surface of liquids. It is best to limit the amount of water crossing the floating weir in order to increase the concentration of contaminant recovered. It is also desirable when skimming water to use pumps that draw water smoothly. Pumps like double diaphragm or helical rotor are best. Ideally the capacity of the pump should be about 5.3 to 6.6 gallons per minute (1200 to 1500 liters per hour). if the pump to be used is over-sized then a by-pass can be introduced along the house to limit the amount of water crossing the weir head. When the skimmer is at rest in the water the floating weir should be just barely breaking the surface of the water. Adjustments can be made if needed. Raise or lower the whole central assembly by loosening the stainless steel bolts holding teh floats, then lower or raise the floats as required.
