The Colchester flood sump has got alien growths in it due to anaerobic decomposition, as a result of the mineral oil film on the tank's surface. Big green snot bubbles as a technical expression.
So....back to the drawing board for separator. I realised the settling tank had to be deeper than first design, to allow oil time to separate and also the inlet needed to be below the surface of the coolant surface to prevent disturbing the coalescent film. This mockup actually works.
The outer bowl is the weir for coolant discharge height. The inner cylinder is the boom to hold the coalescing oil film, coolant passing under it into weir. The dip tube takes the fed coolant to below the surface film and elbow directs it to swirl coolant around boom cylinder. Oil floats, coalesces and as it depth increases flows out of the small inner weir pipe which is a few millimetres above outer weir height and into collection vessel (jamjar). Continuous process and certainly works. New sheet roller on order to produce cylinder(s). Circular construction is to minimise tilting issues. A slight tilt will not stop it working, as the levels drop together. Semi-self levelling.
