The importance of disposing of waste emulsions

The impact of waste emulsion treatment in the mechanical manufacturing industry is very important. Metal cutting processes use a large amount of emulsion for lubrication and cooling. After a period of use, the emulsion will become wastewater and be discharged. Next, let me give you a detailed introduction to the treatment of waste emulsion: The emulsion mainly contains engine oil and surfactants, which are prepared by diluting the emulsified oil with water as needed and adding emulsifiers. In order to improve the rust resistance of the emulsion used in machine tool cutting, sodium nitrite and other additives are also added. At present, demulsification is carried out in the oil collecting tank of the original acid-base system. Sodium humic acid is used as the demulsifier. The wastewater after demulsification is sent to the acid-base system pre sedimentation tank for oil-water separation. Due to the short residence time and natural separation, the separation effect is poor, resulting in high oil content in the sludge precipitated by the acid-base system, which often causes blocking of the inclined plate of the sedimentation tank and the filter cloth of the filter press, seriously affecting the normal operation of the sedimentation tank and the plate frame filter press; At the same time, due to the high concentration of oil in wastewater, it poses a great threat to the stable and efficient operation of detection instruments and water treatment systems in wastewater treatment stations. The above problems in the demulsification system not only bring many troubles to the operation and management of the cold rolling wastewater treatment station, but also cause serious pollution to the water system. Therefore, it is urgent to renovate the existing waste emulsion treatment system. We will wholeheartedly provide users with excellent waste emulsion treatment services, create more perfect services, and sincerely hope to work together with friends from all walks of life to create prosperity.

Disposal method of waste emulsion

The methods for treating emulsion wastewater include chemical demulsification, chemical electrolysis, activated carbon adsorption or ultrafiltration (or reverse osmosis), salting out, coagulation, acidification, and composite methods. The commonly used method is salt precipitation coagulation mixing, which removes surfactants and other substances from water quality purification. Electrolytes are added to the emulsion, and the ions of the electrolyte undergo a strong hydration effect in the emulsion, which is called water competition. This reduces the free water molecules in the emulsion and dehydrates the oil droplets, thereby damaging the hydration layer of the emulsion oil droplets, neutralizing their electrical properties, and damaging their double layer structure, As a result, the oil droplets lose their stability and produce condensation phenomena (electrolytes are generally divided into bivalent and trivalent salts such as calcium, magnesium, and aluminum). Mixed method demulsification pretreatment+micro electrolysis+catalytic oxidation+composite biochemical process Green Water Machinery uses high-temperature catalytic oxidation technology combined with membrane treatment systems, and has advanced technology in the industry in the disposal of waste emulsions. Since its establishment, our company has focused on the disposal of hazardous waste HW09, adhering to the concept of seeking development with integrity and survival with quality, and solving problems for the vast number of enterprises. Has a good reputation in the industry. Jiangyin Green Water Machinery Co., Ltd. sincerely welcomes more enterprises to visit and cooperate with our company!
