KOS-B Oil Skimmers are generally applied to the removal and recovery of floating oils from the surface of water and solution. For best skimming results, oils as well as greases and fats should be immiscible and in a free-flowing state. Meanwhile, the water surface needs to be calm and oil droplets emulsified mechanically in the water require appropriate time to freely rise toward the surface before the water carries them out in the effluent.

 How it works |
|
The motor-driven oleophilic belt rotates two pulleys going in and out of the surface oil layer. Oils stick to both sides of the rotating belt and get wiped out as the belt passes between bisymmetric wiping blades. Wiped oils flow down to the oil trough and then to the built-in oil/water separator. Virtually water-free oils and oil-free water discharge through respective outlets of the separator.

| Features |
|
* Rugged steel construction, simple installation, least
installation space
*Various models: meet different hourly peaks of oil influx
regarded as model selection standard
* Built-in gravity O/W separator: provides additional
separation of even small quantity of water mixed together
with in the oils when skimmed, and is easy to remove
accumulated sludge.
* Adjustable wiper blades: closely contact with both belt
sides
* Uninterrupted skimming function regardless of fluctuating
water level
* Pulley yoke with chains: prevents a tail pulley from
deviating or falling down
* Belt: endlessed and made of chemical resistant poly
material. Heat resistant belts for hot liquids over 60°C are
an option.

»Pre-installation considerations: hourly peak of oil influx, oils(floating, free-flowing), tank(aboveground
or underground), height of skimmed oil holding container, lowest water level, water temperature, electric voltage, etc.
»Support stand for installation: ordinarily excluded from the scope of supply, unless otherwise expressed in writing.
