USE: Oil separators are essential on public roads, petrol stations, parking areas, car washes, car repair shops and in locations where there is possibility of the spill of of light liquids (for example, oil, petrol, diesel oil, lubricants,and heating oil) into the environment. Because all of these substances have lower specific weight than water, they can be separated from water by means of gravity and an installed coalescent filter. Water-soluble and stable emulsions can`t be extracted – for such substances, chemical treatment processes have to be applied.
OPERATION: Water, containing the pollutants, is fed into a sedimentation tank where water current is steadied and solid particles are separated. Partially mechanically pre-treated water is then routed into the oil separator through specially constructed plates made of polyethylene (a ‘plate sedimentator’) which further steady the flow of water in such a way that the separation of sludge is further enhanced and major droplets of light liquids are separated from the water. These plates are well designed to prevent complete blockage of the system. Small droplets of the light liquids are separated out of the water with the help of a coalescent filter. As soon as the quantity of the separated light liquids inside the oil separator reaches a maximum level, a specially designed shut-off valve closes the outflow pipe. This is a sign that the entire quantity of separated oil has to be pumped out of the oil separator through an access shaft. Treated water is then discharged through the outflow pipe
INSTALLATION: The oil separator should be installed in close proximity of the polluted water source. Oil separators are usually installed underground but they can also be free-standing. Installation inside closed spaces is not recommended. Oil separators installed underground can be with or without vehicular access, depending on need and surroundings. They should be installed with easy access for maintenance and emptying. Uncontrolled discharge of oil from the oil separator should be prevented.
