AWD is used to reduce the water content in sludge prior to burning in an incinerator.
Water content of 80-90% in oily sludge mixture from purifyers and bilge drains consists of up to 80-90% of water. Incinerator burns well up to 20-30% of water, higher content of water makes the incinerator inefficient.
AWD removes up to 80-90% off free water from the sludge. A safe Automatic Drain Process gives a low risk of draining oil to the bilge system. A small investment, easy to install on incinerator settling tank.
A gravitational settling device and a oil detection system separates free water from sludge and ensures that if some oil is directed with the water, oil detection system stops the drain process.
Focus has been on a cost effective soloution to separate water out of sludge. No focus on the quality of the water, OWS and/or bildge water separators will treat the water further.
