How to Install an Oil Water Separator for Efficient Separation

Installing an oil water separator is essential for effectively removing oil and other hydrocarbons from wastewater, thereby protecting the environment and ensuring compliance with regulations. Proper installation is crucial for the separator’s efficiency and longevity. This guide provides a step-by-step approach to installing an oil water separator , from site preparation to final testing.

Step-by-Step Installation Guide

 Site Assessment and Preparation

1.1 Assess the Site

  • Evaluate the Location: lift shaft oil  a location that is easily accessible for maintenance and inspection. Ensure the area is well-ventilated and away from any sources of ignition.
  • Space Requirements: Verify that there is enough space to accommodate the separator, including any necessary clearance around it for maintenance and operation.

1.2 Prepare the Site

  • Clear the Area: Remove any debris or obstacles from the installation site.
  • Level the Ground: Ensure the ground is level and stable to support the weight of the separator.

 Select the Appropriate Separator

2.1 Determine Requirements

  • Flow Rate: Calculate the maximum flow rate of wastewater that the separator needs to handle.
  • Oil Concentration: Assess the type and concentration of oil in the wastewater.
  • Regulatory Compliance: Ensure the selected separator meets local and national environmental regulations.

2.2 Choose the Separator

  • Type of Separator: Based on your requirements, choose the appropriate type of separator (gravity, coalescing, or centrifugal).
  • Capacity and Size: Select a separator with the correct capacity and size to handle your specific wastewater characteristics.

 Gather Necessary Tools and Equipment

  • Tools: Wrenches, screwdrivers, pipe cutters, measuring tape, level, and any other tools specified by the manufacturer.
  • Materials: Pipes, fittings, gaskets, sealants, and any additional materials required for the installation.

 Install the Separator

4.1 Position the Separator

  • Placement: Position the separator at the designated location, ensuring it is level and stable.
  • Anchor the Separator: Secure the separator to the ground or foundation to prevent movement.

4.2 Connect Inlet and Outlet Pipes

  • Inlet Pipe: Connect the inlet pipe to the wastewater source. Ensure the connection is secure and leak-free.
  • Outlet Pipe: Connect the outlet pipe to the designated discharge point. The effluent should flow to a safe and compliant location.

4.3 Install Ventilation

  • Vent Pipes: Install vent pipes as specified by the manufacturer to prevent the buildup of gases and ensure proper airflow.
  • Check Valves: Install check valves if necessary to prevent backflow.

 Electrical and Control Systems

5.1 Electrical Connections

  • Power Supply: Connect the separator to a reliable power source. Ensure all electrical connections comply with local electrical codes.
  • Control Panel: Install and configure the control panel for monitoring and operating the separator.

5.2 Sensor Installation

  • Level Sensors: Install level sensors to monitor oil and water levels within the separator.
  • Alarm Systems: Set up alarms to notify operators of high oil levels or any system malfunctions.

 Initial Testing and Calibration

6.1 Leak Testing

  • Pressure Test: Conduct a pressure test on the system to check for any leaks in the pipes and connections.
  • Seal Inspection: Inspect all seals and gaskets to ensure they are properly installed and not leaking.

6.2 Calibration

  • Sensor Calibration: Calibrate the sensors and control systems according to the manufacturer’s specifications.
  • System Check: Run the system and check all operational parameters to ensure everything is functioning correctly.

 Final Adjustments and Commissioning

7.1 Adjust Settings

  • Flow Rate: Adjust the flow rate settings to match the operational requirements.
  • Oil Skimmer: Adjust the oil skimmer settings to ensure optimal oil removal efficiency.

7.2 Commission the System

  • Full Operation Test: Run the system under normal operating conditions and observe its performance.
  • Record Data: Document the initial performance data and make any necessary adjustments.

 Training and Documentation

8.1 Operator Training

  • Training Program: Provide comprehensive training for operators on how to use and maintain the oil water separator.
  • Safety Procedures: Ensure operators are aware of safety procedures and emergency protocols.

8.2 Documentation

  • Installation Report: Prepare a detailed installation report, including all settings, adjustments, and initial performance data.
  • Maintenance Schedule: Establish a maintenance schedule based on the manufacturer’s recommendations and operational needs.


Proper installation of an oil water separator is critical for achieving efficient oil separation and ensuring compliance with environmental regulations. By following this step-by-step guide, you can ensure that your separator is installed correctly, operates efficiently, and requires minimal maintenance. Regular monitoring and maintenance will further enhance the performance and longevity of your oil water separator, contributing to a cleaner environment and safer operations.
