Ship separator PureDry

fuel/water

PureDry ensures waste fuel oil recovery and sludge minimization. PureDry is a fully automated, modular system designed to treat and recover valuable oils found in sludge onboard ships and in power plants. The system separates the waste oil into three phases: cleaned oil, water and super-dry solids. Automated and modular Processes continuously at flow rates of up to 500 l/h Compact, modular system, install in any space Integrates with onboard systems Smart automation adapts process control to feed conditions No water consumption or additional waste generated Alfa Laval PureDry cuts your waste handling and disposal costs. The system eliminates your oily waste by removing water and concentrating solids to a super-dry sludge. Its efficiency allows you to reduce holding tank volumes, freeing up space. You can even achieve fuel savings of up to 2% if FO and LO waste is stored separately. How it works The PureDry system continuously processes oily waste. It has a pumping module with a dosing unit, a heating module, separator module and control unit. A positive displacement feed pump directs the waste oil into the system. The process liquid passes through a duplex strainer and goes into the pre-heater. A three-way changeover valve directs the waste oil to the separation stage. The separator bowl has a disc stack, an oil paring disc and a water paring disc. The disc stack rotates at high speed so solids accumulate at the bowl's periphery. Our patented XCavator device continuously discharges the solids into a container under the separator.
