Oil-water separator

Common methods include gravity separation chambers, which utilize the density difference between oil and water to allow oil to float on the surface for initial separation; coalescers, which use special coalescing materials to combine tiny oil droplets into larger ones, accelerating oil flotation and separation; and some skids are also equipped with membrane separation components, which utilize the selective permeability of semi-permeable membranes to further separate small particles and dissolved substances from oil and water.

Introduction

Structural Composition

Separation Unit: Common ones include gravity separation chambers, which utilize the density difference between oil and water to allow oil to float on the surface, achieving preliminary separation; there are also coalescing separators, which use special coalescing materials to coalesce tiny oil droplets into larger droplets, accelerating the upward separation of oil; some skids are also equipped with membrane separation components, utilizing the selective permeability of semi-permeable membranes to further separate tiny particles and dissolved substances in oil and water.

Filtration Unit: This usually includes coarse filters and fine filters. Coarse filters are used to remove large particulate impurities and suspended solids, protecting subsequent equipment; fine filters can remove smaller impurities and oil droplets, improving the quality of the effluent.

Pump and Piping System: Pumps are used to transport oily wastewater to various processing units, ensuring the flow and circulation of wastewater within the skid. Pipes connect the various components, forming a complete processing flow, and are equipped with valves to control the direction, flow rate, and pressure of the water.

Control System: This generally consists of a control cabinet, sensors, and instruments. Sensors monitor water quality, flow rate, pressure, and other parameters in real-time, transmitting data to the control cabinet. The control cabinet, based on preset parameters and logic, automatically controls the start and stop of pumps, the opening and closing of valves, and the operation of the chemical dosing system, achieving automated operation and running.

Application Areas

Petrochemical Industry: Used to treat oily wastewater generated during petroleum extraction, refining, and chemical production, such as oilfield produced water, refinery wastewater, and chemical plant wastewater.

Metal Processing Industry: Can treat oily wastewater generated during metal cutting, grinding, and stamping processes, recovering cutting fluids and lubricating oils from wastewater to achieve resource recycling.

Food Processing Industry: Used to treat oily wastewater generated during food processing, such as oil refining wastewater, meat processing wastewater, and fried food wastewater, removing oil from wastewater to prevent environmental pollution.

Pharmaceutical Industry: Treats oily wastewater generated during pharmaceutical production, such as raw material production wastewater and preparation production wastewater, ensuring that wastewater meets discharge standards while recovering valuable substances such as organic solvents from wastewater. Shipping Industry: Treats oily wastewater such as ship engine room wastewater and ballast water, meeting ship emission standards and protecting the marine environment.
