    Mill scale separation – Nordic Water. The mill scale contents processed often amount to a full 400 mg/l. This process is also relatively insensitive to oil emulsions and has proved to be very effective at separating them too. A lamella can be used to take care of the wash water from the DynaSand system, or a Sala thickener with a rate of 2 m/h.
