Sewage Treatment Plants
Catalog Overview
Sewage Treatment Plants
Marine sewage treatment plants process wastewater from onboard sanitary systems. Depending on the design, treatment can combine biological processes, separation and disinfection. Maintaining the plant’s treatment functions supports hygienic onboard operation and the vessel’s arrangements for managing sewage discharge.
Restoring treatment performance requires parts that suit the installed plant. ATOZ checks sourcing for the technical team’s maintenance or repair requirement, helping crews prepare the equipment for operational checks and inspection while coordinating parts arrival with the available service period.

Frequently Asked Questions

What is a marine sewage treatment plant used for?
A marine sewage treatment plant processes wastewater generated on board before permitted discharge or transfer to a holding arrangement. Depending on the system, treatment may include biological processing, aeration, separation, filtration and disinfection.
What regulations apply to marine sewage treatment plants?
Requirements for preventing pollution by sewage from ships are addressed by MARPOL Annex IV. The applicable plant approval, discharge requirements and certification depend on the vessel, operating area and administration, so these details should be confirmed for a replacement project.

What information is needed to identify sewage treatment plant parts?
Provide the manufacturer, model, serial number, part number, treatment capacity, number of persons served, process type, electrical data and required quantity. Nameplate photographs, system drawings and manual pages help confirm compatibility.
Can ATOZ supply a complete replacement marine sewage treatment plant?
ATOZ can review complete replacement plants as well as individual spare parts. Provide the required treatment capacity, process and discharge requirements, approval details, installation space, piping connections, utilities and electrical specification.
Can ATOZ source parts for older sewage treatment plant models?
ATOZ can review requirements for older and difficult-to-source sewage treatment plants through its supplier network. Complete equipment details, part numbers, drawings and photographs help identify available options.
