The inclined lamella coalescer is used to separate tramp oil and solid particles from liquids.
The coalescence separator can be made of steel (e.g. for cooling lubricants) or stainless steel (e.g. for decreasing baths).
The effluent is aspirated from the water- / emulsion-surface via a float gauge and pumped into the separator.
The soiled medium flows through the inclined lamellas. As tramp oil is lighter than water or emulsion, it floats on the top, whereas solid particles settle to the ground due to their weight.
Fine oil droplets deposit on the bottom side of the plates, join to form larger drops and finally ascent to the surface due to their buoyancy. The oil drops accumulate in the separator tubes, whereas the solid particles settle onto the top of the lamella and slide down into the sludge funnel.
Coalescers offer the following advantages:
- no risk of blockage through dirt particles due to inclined plates
- no chemical changes of the medium due to a purely mechanical
- bypass operation possible
- no break-down of emulsions, therefore suitable for the treatment of
- pumps rotate at slow speed to protect against dry-running and wear
- increased life of the cooling lubricant
- increased operating life of membrane systems due to pretreatment of
