How does the Extractive Liquid ORZ high-efficiency oil removal treatment achieve deep removal of oil from the extract?
Publish Time: 2024-12-25
Extractive liquid ORZ high-efficiency oil removal treatment is a specially designed process for deep removal of extracts containing oil for purification and recovery purposes. This process usually involves multiple steps and technologies designed to maximize the removal of oil impurities while maintaining the effective components of the extract.1. Physical separation methodGravity sedimentation: Utilize the density difference between oil and water to make oil naturally float or sink, and separate by gravity.Centrifugal separation: Generate centrifugal force through high-speed rotation to accelerate the oil-water separation process and improve separation efficiency.Filtration: Use filter screens, filter paper or other filter media to intercept larger oil droplets and suspended matter.2. Chemical treatment methodDemulsifier: Add demulsifier to destroy the oil-water emulsion system and promote oil-water separation.Flocculant: Use flocculant to aggregate tiny oil droplets into larger particles for easy sedimentation or flotation.Surfactants: Specific surfactants can change the surface properties of oil droplets and promote their separation from the water phase.3. Adsorption methodActivated carbon adsorption: The porous structure of activated carbon is used to adsorb oil substances, which is suitable for removing trace oil pollution.Diatomaceous earth adsorption: Diatomaceous earth has a large specific surface area and can effectively adsorb oil and other organic pollutants.4. Membrane separation technologyMicrofiltration (MF): Intercept larger oil droplets and particles through microporous membranes.Ultrafiltration (UF): Remove smaller oil droplets and soluble organic matter.Nanofiltration (NF) and reverse osmosis (RO): Further remove trace oil and ionic impurities.5. Flotation methodDissolved air flotation: Dissolve air in water and then release it under reduced pressure to form tiny bubbles, which adhere to oil droplets and rise to the water surface to achieve separation.6. Electrochemical methodElectrocoagulation: Flocculants are generated through electrolysis to promote the aggregation and sedimentation of oil droplets.Electroflotation: Use electric field to generate microbubbles to help oil droplets float and separate.7. Biological treatment methodAerobic biological treatment: using microorganisms to degrade oil substances, suitable for biodegradable oils and fats.Anaerobic biological treatment: under anaerobic conditions, microorganisms decompose organic matter, suitable for high-concentration oily wastewater.8. Comprehensive treatment processMulti-stage treatment: combining the above methods, designing a multi-stage treatment process according to the nature and concentration of the oil pollution to achieve the best oil removal effect.In practical applications, Extractive liquid ORZ high-efficiency oil removal treatment The choice of which method or combination depends on the specific characteristics of the extract, the type and concentration of the oil substance, the scale of treatment, and economic feasibility. The goal of high-efficiency oil removal treatment is to remove not only visible oil droplets, but also tiny oil particles and soluble oil substances to ensure that the quality of the extract meets the standards for subsequent processing or discharge.
