Oilsorb-Carbon Treatment Train for Water
1.) First, evaluate if the oil is mechanically or chemically emulsified (for instructions, contact biomin@aol.com). That will determine whether or not you need a pre-treatment tank to break the emulsion.
A.) Next, if the oil content is higher than 20 ppm, start with an oil-water separator.
B.) This is followed by a bag filter of 5 or 10-micron size (depending on flow rate, oil content, and type of suspended solids).
C.) Next, there will be a filter vessel filled with Oilsorb.
D.) Followed by another vessel filled with activated carbon. If heavy metals need to be removed, add another vessel filled with a media such as zeolite (Biomin’s EC-MCL) or hydroxy-apatite (Biomin’s EC-MB, works in hard water).
Precipitation of iron would be done in a tank after the oil-water separator. Get the oil out first.
2.) If you need to use an air stripper for removal of volatiles or ammonia, the procedure is the same, except: Place the stripper in between the Oilsorb organoclay vessel and the activated carbon vessel. The VOCs are removed with a vapor phase filtration vessel filled with coconut carbon.
Why use Oilsorb organoclay? : Because Oilsorb prevents fouling of activated carbon. Oilsorb organoclay, when used to remove oil from water, lasts 7-10 times as long as activated carbon, and saves 50% of operations costs.
