FAQ – Frequently Asked Questions
Q1: What is the typical oil removal efficiency of this equipment?
A: Under normal conditions, our system can achieve an oil content in the effluent of less than 5 ppm, corresponding to a removal efficiency of over 99.9%. Actual performance depends on the inlet oil concentration and flow rate.
Q2: Can the equipment handle emulsions or dissolved oils?
A: Yes, our design includes chemical dosing and coalescing media to break emulsions. For dissolved oils, an optional activated carbon or ultrafiltration unit can be integrated. Please provide your water analysis for a customized proposal.
Q3: What is the mill test report and why is it important?
A: The Mill Test Report is a quality assurance document that contains material certifications (e.g., steel grades), welding test results, and hydrostatic pressure test records. It verifies that the equipment meets design specifications and is traceable to raw materials. This is important for regulatory compliance and asset management.
Q4: How often does the equipment require maintenance?
A: The coalescing cartridges should be inspected every 3-6 months, depending on usage. The system is designed for easy cartridge replacement. Routine checks on pumps, valves, and sensors are recommended. We provide a maintenance manual with each shipment.
Q5: Is the equipment automatic or manual?
A: Standard models are equipped with an automatic PLC control system that manages the separation process, oil discharge, and alarms. Manual overrides are also available. Remote monitoring can be added as an option.
