API Separator - Wastewater Treatment

Dissolved oil forms a true ,molecular, solution with water and cannot be removed by gravity separation. Dissolved oil removal requires biological ,treatment,. The ,API separator,, shown in the graphic below, has become the generic name for “conventional oil-water separators.” Conventional oil-water separators can only remove free oil.

national standard GB-4482-2006 “water ,treatment, agent ferric chloride”, 2 ferrous chloride molecules were added into the system. According to the concentration of the solution, the whole ,simulation, system consisted of 3765 water molecules, 70 Fe3+ ions,2Fe2+ ionsand214Cl ions(atotalof4051particles), which were placed in the box of 5 nm 5nm 5 nm.
