Since the introduction of the IMO resolution MEPC 107 (49) all new vessels must be fitted with bilge water separators capable of breaking up emulsions according to the test rule. The B + V Turbulo bilge water separator gives the optimum balance in terms of function, capital cost, size and maintenance costs. It operates as a pressure system with a helical rotor pump on the inlet side. The initial process of this two-stage bilge water separator utilises a gravitational separator supported by oleophilic coalescer inserts. The second ‘breaking stage’ utilises mechanically-working hydro-carbon separating elements working as a coalescer to separate mechanical emulsions in accordance with the IMO resolution. These elements are highly efficient and high oil concentrations can be processed without substantial pressure losses. It is protected by a special reusable cartridge which is fitted with double bag system, ‘TORC’. ‘TORC’ works as an upside-down/inside out deep filtration unit.
With this system it is possible to extend the lifetime of the top element, thus considerably reducing maintenance costs.
The popularity of the Turbulo-MPB bilge water separator is evidence of the success of this approach.
