Selective Chemical Extraction (SCE™) is a multi-step treatment process customizable to meet any effluent quality including oil and grease removal, H2S stripping, VOC and semi-volatile removal, ion-specific removal and lamella clarification.
The core of SCE is ion-specific induced precipitation utilizing proprietary chemistry plans. Chemically induced reactions with targeted ions forms low solubility components. Divalent ions (Ca, Mg, Ba, Sr, SO4, CO3), trivalent ions (Fe, Al), as well as dissolved silica and boron can be economically removed by this method.
SCE is operated in the oilfield today by Gradiant producing various grades of clean brine at low costs and with minimal operator interference.
