Catalog Overview

Oily Water Separators

Marine oily water separators remove oil from machinery-space bilge water through separation and filtration stages. Oil-content monitoring and discharge controls form part of the overall installation. Keeping these functions serviceable supports the vessel’s arrangements for managing bilge water and preventing oil pollution.

When maintenance or inspection identifies a separation or monitoring issue, repairs need to suit the installed system. ATOZ checks sourcing for the specified components, helping crews prepare the equipment for testing and inspection before returning it to the intended operating duty.

Frequently Asked Questions

Oily Water Separators Supply & Support

What is a marine oily water separator used for?
A marine oily water separator treats machinery-space bilge water by separating oil from water before any permitted discharge. The system is used together with monitoring and control equipment to prevent discharge when the oil content exceeds the applicable limit.
What is a 15 ppm bilge alarm?
A 15 ppm bilge alarm or oil-content monitor measures oil content in the treated discharge. It works with the separator’s control arrangement to activate an alarm and stop or divert discharge when the permitted threshold is exceeded.
Which oily water separator spare parts can ATOZ supply?
ATOZ can assist with coalescer elements, filter cartridges, separator modules, pumps, motors, monitors, sample cells, sensors, valves, solenoids, automatic stopping components, control panels, heaters, seals, gaskets and overhaul kits. Availability depends on the manufacturer and model.
Can ATOZ supply a complete replacement oily water separator?
ATOZ can review complete replacement units as well as monitoring equipment and individual spare parts. Provide the treatment capacity, separator stages, pump data, piping, electrical specification, installation space and required approval or certification.
Can ATOZ source parts for older oily water separator models?
ATOZ can review requirements for older and difficult-to-source separator systems through its supplier network. Providing the manufacturer, model, serial number, part number, system drawings and photographs helps identify available options.
How quickly can ATOZ prepare a quotation?
Quotation time depends on the separator model, required components, monitor and certification requirements, supplier availability and delivery location. Complete technical information and documentation help ATOZ prepare the quotation more efficiently.
Can ATOZ assist with separator servicing and 15 ppm monitor checks?
Depending on the project scope and vessel location, ATOZ can coordinate inspection, cleaning, filter or coalescer replacement, pump and valve work, monitor checks, calibration support, testing and commissioning. Send the equipment details and service scope for review.
Can oily water separator equipment be delivered during a port stay or dry-dock project?
ATOZ can coordinate delivery according to the vessel’s port call or dry-dock schedule, subject to availability and logistics. Include the port, ETA, ETD, required delivery date, equipment weight and local receiving arrangements in your enquiry.
