Hydraulic fracturing in oil and gas fields generates massive flow-back wastewater. The fracturing reverse fluid contains emulsified crude oil, residual polymer additives, suspended solids and high salts. Surfactants form stable oil-water emulsions, making natural separation difficult. Many oilfield sites struggle with high oil content in effluent, which blocks subsequent treatment and prevents wastewater reuse or discharge. A professional fracturing reverse fluid demulsifier is critical for reliable oil-gas field flow-back water treatment.
The stable interfacial film formed by surfactants is the main barrier for oil-water separation. Fine solid particles and high salinity further lock tiny oil droplets. Ordinary gravity sedimentation can only remove free oil. Air flotation and membrane filtration have high operation costs and are prone to fouling. General demulsifiers often fail under high-salinity oilfield conditions, requiring targeted oily wastewater demulsification chemicals.
Shanmei Environment’s fracturing reverse fluid demulsifier breaks the emulsion interfacial film and aggregates micro oil droplets into large flocs. It can work together with PAC and PAM to accelerate oil flotation and solid sedimentation for fast phase separation.
This demulsifier maintains stable performance in high-salinity wastewater. It fits existing sedimentation and flotation tanks without large equipment upgrades. It reduces oil load for downstream processes and helps sites achieve qualified discharge or water reuse. It is widely used for fracturing flow-back liquid and other industrial oily wastewater.
Start with jar tests using on-site water samples to confirm optimal dosage and pH. Add demulsifier under fast stirring to break emulsions, then add coagulants and flocculants. Keep static settlement and adjust dosing rate based on water quality changes.
An oilfield wastewater station faced persistent emulsified oil exceeding limits when treating fracturing reverse fluid. After adding Shanmei fracturing reverse fluid demulsifier, obvious oil-water separation was observed in settling tanks. The supernatant oil content dropped significantly with original facilities unchanged.
Does the demulsifier replace physical separation equipment? No. It serves as chemical pretreatment and still needs sedimentation or flotation units. Is it suitable for high-salinity fracturing flow-back liquid? Yes, jar tests verify its stable demulsifying capacity under high salinity.
Oilfield sites troubled by emulsions in fracturing reverse fluid can rely on this oil-water separation chemical. Contact Shanmei Environment with your water sample data for jar tests and custom dosing recommendations. Email: info@san-mei.com
