ZYFM Series Oily Water Separators

It is constructed by The primary oil water separator, secondary emulsive oil separator, screw pump, electric control box, oily consistency detector, strainer, fine filter and 3-way valve (or solenoid valve), etc.. All of these are installed on a common seat. And if needed the primary oil water separator and electric control box may also be installed separately with secondary emulsive oil separator and oily consistency detector according to different engine room if necessary
The accessory pump does not directly draw from the oily water. Therefore, the emulsion of the oily water is avoided . And the device can gain high separating efficiency.
It use the combination of gravitational separation in vacuum and refined emulsified oil separation method. The oil drops conglomerate and float upward rapidly to the oil collecting room at the top of device when they pass through the tunnel of coalescing element in special degree and special speed. The coalescing element can backflushed it-self automatically, and there will be nearly no blockage happened. In long term usage, no replacement will be needed for coalescing element.
It has good automatic oil discharge control and safety precaution of accessory pump. And can automatically control the primary discharge process or change to the secondary discharge process by the character of the oily-water. Also can put the unqualified water back to bilge when the oil concentration in processed water is beyond the limit. The devicd is easy to operate and highly reliable, and its function accords with requirements for the 24h unattended engine rooms
It is proved that :
The effluence of the device are less than 10PPM when it treat the normal oily water (not emulsified) by using only the primary oil water separator.

The effluence of the device are less than 5PPM when it treat the emulsified oily water by using the primary and secondary separator.
