The second tank separates oil residue from the water. The water distribution system once more ensures the oil contaminated water is evenly distributed. Due to their low density, the larger oil drops rise immediately to the surface. The smaller droplets coagulate, massing inside the separator’s filter system and eventually rising to the surface.
The water exiting through the second separator is free of oil and sludge and can be safely released into the environment. Oil residue and sludge are easily and quickly removed and further processed by outside waste managing companies.
a. Contaminated water enters the separator. Due to the patented Pipelife water distribution system, the water and oil are evenly distributed. The larger oil drops will rise to the water surface due to their low density.
b. Smaller droplets will coalescence and thus increase in size in the filter, and they will eventually rise to the surface.
c. Water leaving the lower outlet is free from oil.
